The major concerns in the usage of phyto-based cosmeceuticals are lower penetration and high compound instability of various cosmetic products for sustained and enhanced com- pound delivery to the beauty-based skin therapy. To overcome these disadvantages, nanosized delivery technologies are currently in use for sustained and enhanced delivery of phyto-derived bioactive compounds in cosmeceutical sectors and products. Nanosizing of phytocompounds enhances the aseptic feel in various cosmeceutical products with sustained delivery and enhanced skin protecting activities. Solid lipid nanoparticles, transfersomes, ethosomes, nanostructured lipid carriers, fullerenes, and carbon nanotubes are some of the emerging nanotechnologies cur- rently in use for their enhanced delivery of phytocompounds in skin care. Aloe vera, curcumin, resveratrol, quercetin, vitamins C and E, genistein, and green tea catechins were successfully nanosized using various delivery technologies and incorporated in various gels, lotions, and creams for skin, lip, and hair care for their sustained effects. However, certain delivery agents such as carbon nanotubes need to be studied for their roles in toxicity. This review broadly focuses on the usage of phytocompounds in various cosmeceutical products, nanodelivery technologies used in the delivery of phytocompounds to various cosmeceuticals, and various nanosized phytocompounds used in the development of novel nanocosmeceuticals to enhance skin-based therapy. Keywords: nanodelivery technologies, skincare, nanophytocompounds, nanophytocosmeceu- ticals, nanotherapy Introduction Cosmeceutical research is a rapid growing area in personal care sectors, which extends from facial products to skin and body products.1–3 A forecasted report suggested that by 2018, the global market for cosmeceuticals will reach ~42 billion dollars and lead to a great demand in near future.4 Even though various synthetic compounds are cur- rently available in the world market, human toxicity is increasing with cosmeceutical interference in certain treatments.5–8 Alternatively, plant-derived natural, bioactive compounds show enhanced beauty roles, along with health benefits against diseases.9–15 Plant-derived bioactive compounds have been used for centuries in cosmeceuticals for a wide variety of beauty treatments for the skin, face, lips, hair, and nail care with beneficial actions against photoaging, inflammation, hair loss, lip care, psoriasis, and ultraviolet (UV) toxicity.13–21 Further, UV radiation causes skin tanning and endothelial cell necrosis and suppresses immunological functions. Some natural phytobioactive compounds can prevent these deleterious effects with skin care.20,22–25 Correspondence: Dong-Kug Choi Department of Biotechnology, College of Biomedical and Health Science, Konkuk University, Chungju 380-701, Republic of Korea Tel +82 43 840 3610 Fax +82 43 840 3872 email choidk@kku.ac.kr Journal name: International Journal of Nanomedicine Article Designation: Review Year: 2016 Volume: 11 Running head verso: Ganesan and Choi Running head recto: Phyto-based nanocosmeceuticals for skin therapy DOI: http://dx.doi.org/10.2147/IJN.S104701 In te rn a tio n a l J o u rn a l o f N a n o m e d ic in e d o w n lo a d e d f ro m h tt p s: // w w w .d o ve p re ss .c o m / b y 1 2 8 .1 8 2 .8 1 .3 4 o n 0 6 -A p r- 2 0 2 1 F o r p e rs o n a l u se o n ly .

These qualities depend on the solubility and size of the active phytocompounds.40,42 This leads us in search of novel, highly promising technolo- gies for enhanced skin health efficiency of cosmeceutical products. Nanotechnology solves most issues with higher protec- tive and skin health-enhancing efficiency. Various nano- technology methods are involved in active roles in beauty enhancement, such as nanoemulsions, liposomes, solid lipid nanoparticles, smaller sized nanoparticles, hydro- gels, and dendrimers.4,43,44 Commercially, many synthetic compounds are used in nanocosmeceuticals that cause toxicity and skin health concerns. Natural phytocompounds are in a greater demand.45–47 Nanoscale phytocompounds used in cosmeceutical products are gradually increasing among products such as sun screens, antiaging, and UV protectants.47–56 Fewer phyto-based cosmeceutical nano- products available in the market are reviewed, namely, vitamin E in acne lotion, tea extracts in nanoshampoo, green tea extracts in the ageless skin care miracle kit, and vitamin E and aloe in UV protection moisture lotion. These phyto-based cosmeceutical nanoproducts contribute to the higher efficacy of the products mentioned for skin-based nanotherapy.57,58 Recent studies suggest that phyto-based nanocosme- ceuticals will play a greater dual role in the near future for their enhanced protective, beauty, and health benefits.4,43,44,59 Therefore, the current review focuses on the different types of nanosized cosmeceuticals, current nanotechnol- ogy usage in the development of nanosized compounds or carriers for the delivery of phytobioactive compounds, and various nanosized phytobioactive compounds used in cosmeceutical therapy for their enhanced skin therapeutic applications. Phytoconstituent-based nanocosmeceuticals for skin therapy Nanoantiaging Aging is the critical factor that causes skin collagen to lose its physical appearance in many ways such as oil production decrease, dry skin, texture loss, age spots, and loose skin. Aging causes skin thinning, and the end result is wrinkle formation.60,61 This is not limited to the aged population; younger individuals exposed to various harsh environmental conditions such as infrared and ultraviolet rays, chemical pollution, and other physical stresses can also be affected.62,63 Currently, various synthetic and natural antiaging creams using nanosize technology are available on the market with enhanced skin protection to moisturize, lift, and whiten skin.64–68 Recently, Lohani et al4 reviewed some nanoproducts produced by few companies for enhanced beauty, such as Hydra Zen Cream, Revitalift, and Skin Caviar Ampoules that contain phytocompounds, using various nanotechnologies. Nanosized phytobioactive compounds, such as curcumin and vegetable oils, show enhanced skin appearance by various antioxidative mechanisms. The aforementioned products prevent skin aging due to oxidative stress and premature aging.69–73 The combination of polyphenols with retinols enhances skin protection. Other than nanosizing, few delivery systems have been used to develop nanoantiaging creams and lotions for the enhanced activity of bioactive compounds to deeper layers of skin. Recently, a nanoemulsion system was constructed using Eysenhardtia platycarpa leaf flavanones with 70 nm nanoparticles that enhanced antiaging activity. Polymeric nanoparticles of E. platycarpa leaf flavanones with the particle sizes between 156 nm and 202 nm also showed the enhanced antiaging effects.74 In addition, coencapsulation of resveratrol and curcumin showed enhanced delivery of phytocompounds for disease treatment with their antioxidant activities and thereby delays aging effects.75,76 Nanomoisturizers Skin dehydration can be prevented by moisturizers, which support skin beauty and enhance skin flexibility by maintain- ing moisture.77 A moisture-preventing barrier on the skin is the stratum corneum, which maintains the skin moisture. Dehydration results in the abundant loss of water from the skin.78 Moisturizer creates a thin film on the outer surface of the skin maintaining skin moisture and can be effectively achieved by various nanotechnological systems.79 Currently, nanoemulsions, nanoliposomes, and solid lipid nanocarriers are effectively used in moisturizer formulations with active In te rn a tio n a l J o u rn a l o f N a n o m e d ic in e d o w n lo a d e d f ro m h tt p s: // w w w .d o ve p re ss .c o m / b y 1 2 8 .1 8 2 .8 1 .3 4 o n 0 6 -A p r- 2 0 2 1 F o r p e rs o n a l u se o n ly .

Among them, safranol was used in the devel- opment of solid lipid nanoparticles with enhanced moistur- izing effects, along with UV protecting activity. In this system, the minimum nanoparticle diameter was 100 nm.80 Similarly, rice bran oil nanoemulsions were also developed with enhanced moisturizing effects to improve various skin diseases, including atopic dermatitis and psoriasis.69 Opuntia ficus-indica (L.) extract mill nanoemulsions were developed with varying particle size from 92 nm to 233 nm and had enhanced moisturizing effects.79 Currently, various vegetable oil nanoemulsions were studied for their potential use as a moisturizer product. In the future, vegetable oils will be a great alternative for enhanced moisturizing effects for dry skin-related diseases.69 Nanoskin cleanser Skin cleanser plays an active role in maintaining skin health.81,82 A thin hydrolipid film covers the skin containing cellular debris from the decomposition products of corneo- cytes and secretions from eccrine, sebaceous, and apocrine glands. Hydrolipid films on the skin surface may attract undesirable microorganisms, which in turn accelerate the odor production with the metabolized products from the sweat glands.83 Skin cleaning directly promotes the removal of skin surface bacteria, which reduces odor production. Currently, skin cleaning products are available on the market from macro- to nanosize containing both synthetic and natural products.84,85 Research is being performed on several phyto-based nanocompounds for enhanced skin cleaning. Recently, phyto-based extracts used in cleansers showed enhanced skin cleansing activity by reducing pore size and skin oil content. However, they are only in the budding stage. The effectiveness of using phyto-based compounds in skin cleansing and related to skin disease such as acne86 is well studied. Similarly, nanosized liposomal lauric acid was constructed in the size range of 113 nm and showed enhanced antimicrobial activity against the acne.87 Another study, using niosomes by combination of lauric acid and curcumin, showed enhanced antimicrobial activity against acne-caused skin infections.88 These studies suggest that phyto-based nanotechnologies show enhanced effects on skin cleanser activity on skin disease. Further, phyto-based nanotechnologies will pave the way for the development of skin cleanser products with phytocompounds with enhanced skin cleaning activity. Nanosunscreens Sunscreens protect the skin from the harmful sun rays exposure.89 Commercially, sunscreens available are in the forms of creams and lotions that contain synthetic compounds, which act as a barrier when the harmful rays hit the skin. Sunscreens prevent deep UV ray penetration and inhibit irritation and other consequences. However, synthetic sun- screens have disadvantages, including formation of a chalky layer, greasiness, smelliness, decreased appeal, and toxicity.90 A few of the mentioned disadvantages are overcome by use of natural phyto-based active ingredients. Recently, Bulla et al91 studied the usage of phyto-based bioactive compounds derived from Schinus terebinthifolius Raddi in sunscreens and found that they enhance antioxidant and sun blocking activities. Similarly, bioactive-rich dried extracts of Brazil- ian Lippia species showed higher photoprotective activity.92 Even though phytobioactive compounds show increased sunscreen effects, their stability and skin protective effects were greatly enhanced by using nanotechnology delivery systems in the sunscreen cream and lotions.73,93,94 Recently, saffranol was constructed using solid lipid nanoparticles and had enhanced sun screening activity in the size range of 103–233 nm.80 Similarly, nanostructured lipid carriers were constructed using rice bran oil and raspberry oil and had enhanced sunscreen activities with higher antioxidant and UV protective activities.95 In another study, phytoflavanoid- encapsulated poly(lactic-co-glycolic) acid nanoparticles were constructed with the particle size of 90–100 nm that had enhanced sunscreen activity along with increased antioxidant activity. In another study, a pomegranate seed oil nanoemul- sion was constructed with various nanoparticle sizes and showed increased skin protection against photodamage with enhanced antioxidant activities.96 The same research group also studied the effect of pomegranate seed oil nanoemulsions on human erythrocytes and found increased photosafety of lipid skin membranes.97 The earlier research suggests that the development of novel nanosized phytocompounds will enhance sunscreen products with fewer toxic effects. Nanohair care Hair care is the most promising cosmeceutical sector. People of all ages are concerned about their hair. Hair loss may occur at any age. Hair loss conditions are associated with scalp In te rn a tio n a l J o u rn a l o f N a n o m e d ic in e d o w n lo a d e d f ro m h tt p s: // w w w .d o ve p re ss .c o m / b y 1 2 8 .1 8 2 .8 1 .3 4 o n 0 6 -A p r- 2 0 2 1 F o r p e rs o n a l u se o n ly .

Along with hair growth, the phyto-based bioactive compound mixture protects from hair loss and breaking. Recently, a nanocosmeceutical-based approach of promoting hair growth was achieved using delivery tech- nologies, such as niosomes and liposomes, to hair follicular cells.106–113 Curcumin-based liposomes were constructed and had 70% enhanced penetration of the curcumin to the hair growth, irrespective of liposomes type in the size range of 213–320 nm.114 Similarly, a curcumin-based cyclodextrin complex also showed enhanced follicle penetration and hair growth enhancement.115 In addition, the combination of polyarginine and oleic acid-modified nanoparticles in size range of 140–143 nm showed enhanced skin penetration of follicular or nonfollicular cell pathways.116 These studies confirm that higher penetration of bioactive molecules from the plants can be enhanced by nanotechnology to develop better hair growth, disease treatment, and beauty therapies. Nanonail care Nanonail care is a promising novel cosmetic and health care sector. Nanonail care particles are developed using synthetic particles and show increased protective effects against nail infections. This treatment increases nail glow and toughness in mammals.43,44 However, the use of synthetic nanoparticles has a decreased market impact compared to natural products. Therefore, the demand of phyto-based nail care products is gradually increasing. Natural, plant-based pigments mostly consist of phytobioactive compounds and have various therapeutic effects. Bioactive compounds from plants are rich in color such as carotene (orange color), chlorophyll (green), and curcumin (yellow), lycopene (reddish orange), anthocyanin (red/purple), and annatto (yellow/orange). These compounds were used in the traditional practices of mixing colored extracts with honey, ghee, or coconut oil for skin and nail care.117,118 These bioactive compounds have antibacte- rial, antifungal, antiviral, and antioxidant health enhancing effects. Even though these compounds are used in foods and cosmetics at the macro- or microlevels, the use of the natural pigments at the nanolevel is limited. Recently, asynthetic nanoemulsion was developed with enhanced antifungal activity against nail infections.119 Turmeric and henna are rich in phytobioactive compounds, and their role in the nail care is well known. However, the role of nanosized turmeric and henna bioactive compounds remains unstudied. Further, during nanosizing, the colors and their effects may enhance or change, which will give future researchers a broad range of the nanonail care cosmetics to study. Nanolip care Nanolip cosmetics are another growing nanosector. Cur- rently, various synthetic and metal particles are used at the nanosize for effective lip protection, enhanced color. These products last longer and have a homogenous distribution.4 The use of nanometal particles enhances the even distribu- tion of pigments over the lips to increase protection. Since lips are most vulnerable skin-type, caution is necessary when using synthetic and metallic nanoparticles. Generally, phytoconstituents are used in the lip care at the macro- and microlevels such as coconut oil, curcumin, and other bioac- tive compounds that have increased protective activity.120,121 Recently, plant betalains, a novel dietary-colored indole- derived pigments, were efficiently used in the lip care prod- ucts and the extraction of those compounds and their encapsu- lation enhances storage stability122–124 and applications. Bixa orellana was used as a colorant for lip jelly and was found to have higher organoleptic lipstick properties. Similarly, propolis was also used in the development of a novel lipstick. However, the use of nanotechnology in phyto-based lipstick development is still in the budding stage. Phytoconstituent-based nanodelivery systems in cosmeceuticals for beauty and health care Limitations of synthetic bioactive ingredients used in cosmeceuticals increase the demand of nanosized phyto- based bioactive ingredients that can be applied by nano- delivery systems.64,69,80,93 Nanodelivery systems enhance the solubility of the active phytobioactive compounds and penetrate through the skin. Penetration enhancement of active phyto-based ingredients was achieved through suit- able nanodelivery techniques that led to increased cosme- ceutical effectiveness.50,51,96,110,125,126 In addition, phyto-based bioactive ingredients solve most skin diseases, and thereby, nanotechnology enhances the therapeutic value of dual role In te rn a tio n a l J o u rn a l o f N a n o m e d ic in e d o w n lo a d e d f ro m h tt p s: // w w w .d o ve p re ss .c o m / b y 1 2 8 .1 8 2 .8 1 .3 4 o n 0 6 -A p r- 2 0 2 1 F o r p e rs o n a l u se o n ly .

Further, nanoparticle formulation increases retention of the product on the outer skin layer. Various nanodelivery techniques used in the formulation of cosme- ceuticals are of solid lipid nanoparticles, nanostructured lipid carriers, liposomes, phytosomes, nanoemulsions, nanonio- somes, nanocapsules, and nanolipospheres.4,57,70 Solid lipid nanoparticle-loaded resveratrol showed enhanced permeation in the porcine skin.127 Similarly, colloidal silica emulsion loaded with quercetin also showed enhanced human skin per- meation owing to the nanosizing of the compounds.128 Even though various nanotechnology systems enhanced deeper penetration of phytocompounds that are currently available in cosmeceuticals, technology usage depends upon the type of bioactive ingredients, such as hydrophilic or hydrophobic, gel or emulsion, size, degradability, and toxicity. In this section, we discuss the type of nanotechnology delivery techniques used for the development of phytobioactive compound-based nanocosmeceuticals. Solid lipid nanoparticles Solid lipid nanoparticles are among the nanotechnologies exten- sively used in both pharmaceuticals and cosmeceuticals.45,48,49 Commercially, many cosmeceutical companies produce cosmeceuticals using this technology to enhance beauty and therapy. This nanoparticle system developed from micro- emulsion systems using solid lipids such as stearic acid, cetyl, and palmitic acid along with plant-derived phytocompounds such as flavonoids, phenolic acids, and other active com- pounds. Solid lipid nanoparticles have advantages in stability, higher production, and long-term storage compared to other conventional and nanodelivery techniques.44,50,80,110 Solid lipid nanoparticles also boost the cosmeceutical efficiency by enhancing properties that includes hydration, lower uptake of the systemic circulations, therapeutic values, prolonged, and sustained release in the skin and hair. Recently, sesamol- loaded solid lipid nanoparticle was constructed with the par- ticle size of 127 nm for usage in skin cream, which increased the apoptotic nature of the skin.129 Vitamin A-loaded solid lipid nanoparticles were constructed with the particle size of 200 nm and increased skin moisture retention and skin occlusive effects in porcine skin.130,131 Similarly, curcumin, another bioactive compound, was constructed using solid lipid nanoparticles with the particle size of 210 nm. This packaging of curcumin showed enhanced activity in hydro- gels prepared for inflammation treatment of porcine skin.132 However, some solid lipid nanoparticles showed a higher particle size with the addition of quercetin, an average of 574 nm. This size can be reduced with the addition of silica, decreasing the average size to 483 nm causing enhanced skin penetration of quercetin with higher photostability and skin protection.128,133 In another study, caffeine-loaded solid lipid nanoparticles were constructed, with a particle size of 182 nm and enhanced skin permeation of the bioac- tive compound with higher skin protection.134 Similarly, resveratrol-loaded solid lipid nanoparticles with a particle size of 180 nm showed higher skin permeation with enhanced protection.135,136 Lutein-loaded solid lipid nanoparticles with the various nanosizes showed increased skin protection from the UV light and antioxidant activity retention, thereby prolonging skin health.137 From the earlier research studies, solid lipid nanoparticles made with plant-based bioactive compounds suggest that cosmeceutical efficiency and health benefits are increased. Solid lipid nanoparticles may promote this sector with further development of phyto-based solid lipid nanoparticle formulations with multiple applications in therapy-based nanocosmeceuticals. Nanostructured lipid carriers Nanostructured lipid carriers are another important delivery technology used in cosmeceuticals to deliver natural and synthetic bioactive ingredients with increased efficiency.138–140 This technology has more advantages than other nanotechnologies in bulk production, increased sta- bility of the carriers, and is different from solid lipid nano- carriers with the use of liquid lipids such as oleic acid. In addition, nanostructured lipid carrier has different structures such as imperfect type with different lipid structures, form- less type with lipid preventing crystallization, and multiple type with the lipid oil containing bioactive compounds thereby limit the expulsion of bioactive compounds, which is a major drawback in solid lipid nanoparticles. Several phytobioactive compounds are highly used in the prepara- tion of nanostructured lipid carriers with high efficiency in the topical applications, thereby protecting the skin and enhancing beauty. Okonogi and Riangjanapatee141 recently developed a nanostructured lipid carrier for topical deliv- ery of lycopene with particle size ranging from 150 nm to 160 nm. Similarly, a lutein-nanostructured lipid carrier with particle size of 166–350 nm was constructed and tested for UV protection in the pig ear skin studies. These studies confirm that the lutein nanoparticle formation and their skin protective effects vary with nanocarrier type. Solid lipid nanocarriers showed higher lutein photostability followed by nanostructured lipid carrier and nanoemulsion. Moreover, the stability of all three types of nanocarriers showed better photoprotection of the skin.137 In te rn a tio n a l J o u rn a l o f N a n o m e d ic in e d o w n lo a d e d f ro m h tt p s: // w w w .d o ve p re ss .c o m / b y 1 2 8 .1 8 2 .8 1 .3 4 o n 0 6 -A p r- 2 0 2 1 F o r p e rs o n a l u se o n ly .

This quercetin product enhances the beauty of the skin from preventing oxidative stress.138 Similarly, nanostructured lipid carrier was con- structed using phenylethyl resorcinol with a particle size of 218 nm and showed enhanced photostability and water stability, which may be applied as a whitening agent in the near future.142,143 Resveratrol was also constructed using nanostructured lipid carrier systems in the size range of 110 nm and showed enhanced skin protection with higher antioxidant activity, than solid lipid nanoparticle-loaded resveratrol.144 Further E-resveratrol greatly protects skin through the lipid-based nanoparticle system, under UV radiation.145 In certain studies, some bioactive compounds, such as squalene, promote drug absorption to the hair fol- licles, for example, a squalene-enriched nanostructured lipid carrier with a particle size of 208–265 nm is used to treat hair follicles of individuals suffering from alopecia areata.146 From these recent research studies, we confirm that nanostructured lipid carrier systems will open a gateway for phytobioactive compounds to enhance beauty and personal care. Nanosingle or multiemulsions Single or multiple nanoemulsions are currently used in various cosmetic products for their specific application using sizes between 10 nm and 300 nm with enhanced activity.69,147,148 The major advantages of using nanoemulsions in cosmetics are their unique size, which can enhance the bioactive activity of both hydrophilic and lipophilic types. However, this method has limitations in cosmeceutical production due to instability of emulsions during storage.149–158 Further, the emulsion core compounds direct whether a single or multiple nanoemulsions can be formed based on their number of core compounds in the nanosized emulsions.159,160 Multiple emulsions have advan- tages over single emulsions, due to their wider applications in cosmeceuticals, which can further reduce cosmeceutical cost. Several plant-derived bioactive compounds are used in nano- emulsions, such as flavonoids and polyphenols. Their bioactive role enhances cosmeceutical value with lower toxicity.161–164 Recently, quercetin-rich nanoemulsions, in the size range of 200–300 nm, were prepared from the ethanolic extract of Achyrocline satureioides and showed increased skin retention of bioactive compounds with enhanced antioxidant activities in porcine skin studies.164 In another study, genistein, a soy bioac- tive compound, coloaded with tocomin, acts as multiple nano- emulsions with the particle size of 173–208 nm and showed enhanced skin protection from UV damage. This treatment will be useful in the sunscreen lotion production.165 Similarly, retinyl palmitate was used in the production of nanoemulsions in the size range of 275 nm and showed enhanced skin penetration with increased inner skin protection.166 Similarly curcumin nanoemulsions were developed using a self-nano- emulsifying method with the mean particle size of 85 nm and showed enhanced transdermal availability with high perme- ability and without degradation.71 This might be useful in the skin care sectors for developing novel skin cream emulsions. In another study, lutein was successfully encapsulated into nanoemulsions in the size range of 150–350 nm and increased the release of the active compound compared to other lipid carriers. It showed comparatively better protection than corn oil suspended lutein.137 Nanoemulsions are highly used in skin-based beauty therapy. Achyrocline extract nanoemulsions show enhanced protection against herpes virus infections.161 Even though these phytocompound-rich single or multiple nanoemulsions showed better protective effects in various cosmeceuticals compared to commercial macroformulations, the stability of nanoemulsions is a big issue in the production and commercialization of these delivery technologies in the cosmeceutical sectors. Lipid-based nanocapsules Lipid-based nanocapsules show promising effects in bio- medical applications along with cosmeceuticals.59,167–169 These delivery systems have enhanced effects in the delivery of phytobioactive compounds in oral therapy, which boosts the cosmeceutical sectors for the development of cosme- ceuticals with enhanced activity by topical application. However, synthetic compounds are extensively developed using this technique,170 and phytocompounds used for cos- meceuticals are limited. Recently, resveratrol and curcumin were constructed using lipid core nanocapsules at 201 nm with an increased retention of polyphenols in the skin and increased skin protection.59 This confirms that coencapsula- tion enhances the bioavailability compounds in the skin and promotes skin protection against physiological environments. This technology will be potentially useful in the near future of the cosmeceuticals sectors. Similarly, an individual phyto- compound of resveratrol was constructed using lipid-derived nanocapsules at 207 nm that enhanced skin protection with higher bioavailability of those bioactive compounds under UV radiation.145 Chitosan hydrogels combine nanocapsules with the active compounds of capsaicinoids and enhance skin protection by the control release of those compounds.171–173 The same research group studied the effects of capsaicinoids In te rn a tio n a l J o u rn a l o f N a n o m e d ic in e d o w n lo a d e d f ro m h tt p s: // w w w .d o ve p re ss .c o m / b y 1 2 8 .1 8 2 .8 1 .3 4 o n 0 6 -A p r- 2 0 2 1 F o r p e rs o n a l u se o n ly .

Nanophytosomes Phytosomes are another novel technology, particularly for plant polyphenolics, which enhance bioavailability of phyto- bioactive compounds to the skin5 and in other therapeutic applications174–177 for skin beauty and health care. The greater advantage of these techniques involves chemical bonding between the polyphenolics and the lipid bilayer and thereby enhances the physical stability of bioactive compounds, which prolong the compound’s effectiveness.178,179 Phytosomes are extensively used in cosmeceutical sectors for their beauty and therapeutic applications with the phyto-derived crude extracts or with the individual bioactive compounds.179,180 Recently, extracts from the Citrus auranticum and Glycyrrhiza glabra were used for the construction of phytosomes and for the skin aging studies. The researchers confirmed that phytosomes enhance the bioavailability of those compounds in cream and thereby protect skin from aging.181 Further, nanosizing of those phytosomes increases the bioavailability of those compounds for beauty and health care applications.182,183 Gold nanoparticle-bound phytosomes containing phytoextracts rich in quercetin were constructed and had enhanced querce- tin efficiency at a particle size of 100 nm.184 Similarly, rutin- based phytosomes were developed with enhanced compound bioavailability and antioxidant activity.185 Nanoliposomes Liposomes are effective in carrying phytobioactive compounds in cosmeceuticals. Products containing liposomes increase skin protection and beauty qualities.43,186–189 Generally, nano- liposomes are spherical, have a uni- or multilamellar struc- tures, and are a few nanometers in size. Liposomes have high efficiency in phyto-based compounds delivery to the dermal layer. Nanoliposomes are used in cosmeceutical products such as antiaging cream, sun block cream, hair cream, and skin moisturizer, which contain synthetic as well as phytobioactive compounds.43,187–189 The major advantages of nanoliposomes are their unique size, they can encapsulate hydrophilic and hydrophobic bioactive compounds, UV absorbing lipids can protect the skin and the bioactive compounds without further degradation.43,187 Figure 1 shows the possible nanoliposome mechanism in reducing skin wrinkles. Among nanoliposomes that contain phytobioactive compounds, curcumin was studied with enhanced stability and prolonged activity of transdermal application.190 Recently, curcumin-loaded 80 nm nanoli- posomes were constructed and showed skin protection.191 Figure 1 Nanoliposome-based delivery of antioxidants for skin wrinkles in antiaging treatment.

Phytocompound-encapsulated liposomes will be an innovative technology in the near future for application in therapy-based beauty. Nanoniosomes Niosomes are extensively used in cosmeceutical sectors since it has multiple advantages over liposomes such as higher stability, enhanced skin penetration, low toxicity, and higher protection of the bioactive compounds.194–196 Niosome sizes vary from nanometer to micrometer, the lower the size greater the efficiency. Nanoniosomes are smaller, unilamellar structures in the size range of 10–100 nm.197–200 Niosomes are extensively used to deliver antioxidants such as ascorbic acid, resveratrol, and ellagic acid through skin and are used orally to treat diseases.196,201–207 Even though commercially many cosmeceutical creams and lotions contain niosomes with synthetic compounds, phyto-derived bioactive compound usage is a new sector in the development of nanoniosomes. Recently, Tavano et al202 produced a slightly larger niosome in the size range of 471–565 nm containing phyto-derived anti- oxidants such as resveratrol, alpha-tocopherol, and curcumin. This product showed enhanced antioxidant activity to the skin with increased skin permeation activity for cosmeceuti- cal applications. This study confirmed that phyto-derived compounds can be effectively used in noisome formulation for cosmeceutical applications without change in bioactivity and enhanced skin protection. However, the size is a big factor, and reduction to nanosize with alteration in produc- tion methods may enhance their activity with a broad range of applications in cosmeceutical sectors. Recently, individual phytocompounds, such as curcumin, were developed using nanoniosome methods in the size range of 91 nm and showed enhanced skin protective activity.208–215 From the earlier studies, phytocompound-containing nanoniosomes may be useful for both cosmeceuticals and pharmaceutical sectors. Nanoethosomes, glycerosomes, and hyalurosomes Ethosome, glycerosomes, and hyalurosomes are modi- fied liposomes, named based on their compounds used in the phospholipids, such as ethanol, glycerol, or sodium hyaluronate. They are modified for the enhanced delivery of the active ingredients to the skin and exclusively used in cosmeceutical sectors for their therapy and beauty treatments.216,217 Further, nanosizing of vesicles with incorpo- ration of phytocompounds showed enhanced protective and beauty activity.218–221 Recently, quercetin glycerosomes were developed in the size range of 80–110 nm with a unilamellar structure and showed enhanced skin protective activity.222 This may be used in the future for the production of antioxi- dant skin cream. Ethosomes nanovesicles in the size range of 128 nm were prepared with polyphenolic extracts of Fraxinus angustifolia leaf and bark and showed enhanced wound heal- ing and skin protection activity.223 Similar to the ethosomes, nanosized hyalurosomes of liquorice extract were prepared in the size range of 100 nm and enhanced skin beauty.224 The same research group also developed curcumin-based nanohyalurosomes with a minimal particle size of 112 nm and showed enhanced skin beauty-based therapy.193 From these studies, extracts can be used to develop nanovesicles, which could be efficiently used in the cosmeceutical sector, and it will give a broader scope of research and development for cosmeceutical products with multiple efficiencies. Fullerene Fullerene is yet another novel technology made of carbon atoms of 1 nm size, consisting of even numbers known as C60, which is used in the cosmeceutical sectors to carry phy- tocompounds. Fullerene itself acts as an antioxidant and pre- vents premature skin aging.225–229 Fullerene delivers vitamins to effectively enhance the skin. Recently, some researchers developed a fullerene nanocapsule with ascorbic acid and vitamin E. It showed enhanced skin protective activity against premature aging by its antioxidant activities.230,231 Further, skin protection was also enhanced by the fullerenes with some modifications.232–234 Fullerene-based photodynamic therapy was used for skin-based disease treatment with the bioactive compounds, such as curcumin.235,236 However, further study on the application of various phyto-derived bioactive com- pounds with fullerenes in cosmeceutical-based skin therapy has yet to be carried out. This will give way for the develop- ment of the new cosmeceutical products with better protective activity by the carrier and bioactive compounds. Carbon nanotubes Carbon nanotubes are a novel technology currently used in the cosmeceutical sectors particularly for the skin care. Similar to fullerene, carbon nanotubes alone act as an antioxidant at 100 nm in size.237,238 In addition to their uses in In te rn a tio n a l J o u rn a l o f N a n o m e d ic in e d o w n lo a d e d f ro m h tt p s: // w w w .d o ve p re ss .c o m / b y 1 2 8 .1 8 2 .8 1 .3 4 o n 0 6 -A p r- 2 0 2 1 F o r p e rs o n a l u se o n ly .

However, a study on the application of carbon nanotubes with phytocompounds in skin care and cosmeceuticals is yet to be done. Phytoconstituents in nanosize cosmeceuticals and skin therapy Nanosize phytoconstituents are gaining popularity among the active ingredients in the cosmeceuticals, as they enhance beauty and have therapeutic roles in diseases such as antiaging, UV protection, and prevention of skin-related diseases.190,243–246 Increased skin protective activity of bio- active compounds is related to polyphenol content along with their reduced size. Compounds vary from macro to nano and with skin penetration using different delivery techniques.193,247–251 Recently, resveratrol encapsulated in the solid lipid nanoparticle showed enhanced skin uptake with increased protection and antioxidant activity.144 Solid lipid nanoparticles were compared nanostructured lipid carrier systems and found similar efficiencies with increased reten- tion in the skin. Nanodelivery technologies also enhance the compound bioavailability not only to the skin but also to the brain to treat disorders such as Parkinson’s disease.252 Further modification of bioactive compounds along with the nanodelivery technologies can enhance skin bioavailability to increase protection.145 Similarly, quercetin encapsulated into a solid lipid nanoparticle system showed increased skin reten- tion of quercetin with greater antioxidant activity.138,253,254 Genistein-loaded nanoemulsions were incorporated into hydrogels in the size range of 250 nm and enhanced delivery of the bioactive compound to the skin for a beauty-based therapy. In addition, coencapsulation of resveratrol and cur- cumin with lipid core nanocapsules increased delivery of the resveratrol to the skin.59 Further, several other phytobioactive compounds were efficiently encapsulated into various nano- delivery systems to enhance beauty and therapy applications. Specific compounds, their skin protecting activity, and beauty applications are discussed in the following sections. Some of the nanophytobioactive compounds and its role in beauty and skin therapy are listed in Table 1. Nano Aloe vera Aloe vera consists of several active constituents such as proteins, minerals, carbohydrates, and vitamins from the inner portions of the leaf, which are widely used in the skin care and the medicine.255–259 Aloe gel greatly enhances mois- turizing activity and antiaging by enhancing the synthesis of collagen and elastin fibers. In addition, it also helps in the wound healing.257–263 The higher moisture, bioactive compound, and mineral content of aloe gel enhance the moisturizing effects and skin protection. Therefore, aloe is often used in cosmetic products such as creams, lotions, and gels.189,264,265 However, for their enhanced bioactivity of the aloe compounds, nanodelivery techniques are recently used in the cosmeceutical sections. Further, the use of nanosize A. vera in the preparation of cosmeceutical products is now in early stages. Few nanotechniques enhanced skin care activities. A. vera gel extract liposomes were constructed, with the particle size of 200 nm, that enhanced skin collagen synthesis and growth of skin cell lines, which confirm that it may be used to enhance skin care products.189 Similarly, some researchers patented nanoemulsion technology varying the nanosize containing A. vera extract. The resulting prod- uct caused skin rejuvenation and had antiwrinkle activity. In addition, coencapsulation of A. vera with curcumin enhances phytocompound delivery to the skin and protects antioxidant activity.266 From the earlier studies, nanosiz- ing bioactive compounds from A. vera enhances beauty applications. Further development of various nanodelivery techniques is a good research opportunity. Nanocurcumin Curcumin is the active compound in turmeric, which is native to India and other Asian countries. Turmeric is widely used in cooking, medicine, beauty, and health products.267–273 Turmeric as a crude extract or tuber powder normally used for skin care among South Indian women in their daily rou- tine owing to its multibeneficial activities such as antiaging, moisture retention, antioxidant activity, and natural beauty products with yellow pigments.274–281 Although turmeric has multiple beneficial activities, its bright yellow color and instability under certain environmental conditions make researchers look for alternative delivery technologies for skin care and beauty applications. Nanodelivery techniques such as solid lipid nanocarriers, nanoliposomes, nanonio- somes, and nanoemulsions solve most of their difficulties with turmeric and enhance the bioavailability of its polyphe- nolic compounds in cosmeceutical product.4,43,44 Curcumin nanotransfersomes, nanoethosomes, and nanoliposomes were prepared and studied for the skin hydration and UV protec- tion activity. Three nanodelivery technologies enhanced the delivery of curcumin to the skin with greater hydration and UV protective in cream containing the nanoformulations.

They also varied in size from 167 nm to 262 nm.219 In another study, curcumin nanoethosomes were prepared with particle sizes of 216 nm and enhanced antiwrinkle properties. Further, skin permeation of the curcumin-loaded nanoliposome with particle sizes of 82–92 nm showed higher skin protection.191 Similarly, nanohyaluronosomes with particle sizes of 112–220 nm enhanced curcumin bioavail- ability to the skin and will potentially be used for beauty- based therapies in near future.193 Similarly, curcumin-loaded niosomes were prepared with enhanced bioavailability in the skin.282 In addition to the individual compounds, coad- ministration of curcumin with resveratrol in the lipid core nanocapsules increased delivery of the phytocompounds to the skin with better antioxidant potential and skin care.59 Likewise, codelivery of curcumin with resveratrol in the nanosized niosomal formulations enhanced skin beauty with increased antioxidant activity.202 Nanovitamin e Vitamin E is heat stable fat soluble compound most com- monly used in cosmeceuticals for skin protection properties such as antiwrinkle, enhanced skin moisturizing, and preven- tion of skin disease.283 Since most cosmeceutical products contain the precursor of active tocopherol and its cleavage products in the skin is minimal, which leads to a decrease in skin protection. Even though vitamin E is naturally present in human skin, most of it is not active due to prolonged solar irradiation. Nanodelivery techniques solve issues with suf- ficient delivery along with prolonged and sustained release of vitamin E associated with enhanced beauty. Vitamin E nanoemulsion was prepared using nanoemulsion techniques and enhanced bioavailability of the vitamin compared to microsized emulsions.284 Vitamin E was also prepared using Table 1 Nanosized phytocompounds used in cosmeceuticals S no Phytocompounds Nanodelivery methods Size (nm) Applications References 1 Rice bran oil Nanoemulsion 69 Moisturizers Bernardi et al69 Antiaging Skin care Skin care 2 Rice bran and raspberry seed oil Lipid nanocarriers Sunscreens Niculae et al95 3 Lavender extracts Polymeric poly(lactic-co-glycolic) acid (PLGA) nanoparticle 301–303 Antiaging Pereira et al350 Antioxidant 4 Rosemary extracts Solid lipid nanocarriers 57 Antioxidant (skin) Lacatusu et al351 Nanostructured lipid carriers 68 Antioxidant 5 Aloe vera extract Nanoliposome 200 Skin care Takahashi et al189 6 Saflower extracts Nanostructured lipid carriers 100 Hair care Kumar et al352 7 Lutein Nanostructured lipid carriers and nanoemulsion 150–350 Skin care Mitri et al137 8 Quercetin Nanostructured lipid carriers 215 Skin care Guo et al353 9 Ganoderma triterpenoids Nanostructured lipid carriers – gel 179 Skin enhancement Shen et al354 10 Hinokitiol Poly(epsilon-caprolacton) nanocapsules 223 Hair care Hwang and Kim355 11 Hinokital Bilayer vesicles Hair growth Yang et al356 12 Curcumin Nanoencapsulation 190 and 276 Skin care Suwannateep et al357 13 Tocopherol Nanostructured lipid carriers (NLCs) and nanoemulsion (Ne) 67 and 576 Skin care Abla and Banga358 14 Resveratrol Solid lipid nanoparticles versus nanostructured lipid carriers 287.2 and 110.5 Skin care Gokce et al144 15 Resveratrol Niosomes 299 Skin care Pando et al196 16 Resveratrol and curcumin Lipid care nanocapsules 202–209 Skin care Friedrich et al59 17 Resveratrol, alpha-tocopherol, and curcumin Niosomes 471–565 Skin care Tavano et al204 18 d-Limonene Nanoemulsions 54 Skin care Lu et al359 19 Aqueous propolis and lycopene Nanoemulsions NA Skin care Butnariu and Giuchici360 20 Lycopene Transfersomes 124 Skin care Ascenso et al208 ethosomes 154 Skin care Ascenso et al208 Abbreviation: NA, not available.

Further, solid lipid nanoparticle vitamin E preparation enhanced vitamin E delivery for cosmeceutical-based skin therapy.285–290 Teo et al291 reported that vitamin E-enriched palm oil nano- emulsions with particle sizes of 94 nm enhanced product stability and may be useful for their novel nanosized cos- meceuticals. In near future, vitamin E will be delivered with suitable nanodelivery technologies in therapy-based cosme- ceuticals for enhanced activity, stability, and beauty care. Nanovitamin C Vitamin C is a vitamin abundant in plants and has multiple roles in the beauty and health care, involving collagen synthesis.292,293 Vitamin C readily undergoes degradation when exposed to harsh environments and UV radiation. A continuous supply of vitamin C compounds enhances the skin’s beauty. Nanodelivery techniques help sustain vitamin C supplementation without changes in its biological activity after applying to the skin. Recently, several nanotech- nological approaches have been published using vitamin C for skin health and beauty, such as solid lipid nanoparticles and nanostructured lipid carriers.294 Vitamin C-encapsulated solid lipid nanoparticle was prepared with a particle size of 200–225 nm. Solid lipid nanoparticle enhanced the carrier of the vitamin against apoptotic effects.295 Similarly, nanolipo- somes were constructed using vitamin C that enhanced skin permeation activities with different particle sizes, ranging from 66 nm to 130 nm.296 In addition, vitamin C nanolipo- somes had enhanced stability and higher antioxidant activity compared to ordinary liposomes after 60 days of storage.297 In another study, a vitamin C and gold-loaded nanofiber mask were prepared for the effective delivery of vitamins to the face. The liposomal preparation delivery of vitamins through mask enhanced facial beauty.298 Therefore, vitamin C can be delivered to the skin using nanodelivery technologies for enhanced skin beauty-based therapies. Nanoresveratrol Resveratrol is another polyphenolic compound with multiple beneficial roles in quenching free radicals and protecting skin against harmful environmental conditions.299 Polyphenolic compounds inhibit oxidative mechanisms and UV-induced radiation. They are widely used in functional foods for skin care and health.56,300–304 In comparison to other antioxidants, resveratrol shows higher efficiency of skin protection against UV-B radiation.305,306 However, resveratrol stability and beauty effects are limited due to compound degradation under harsh environmental conditions. To overcome this, nanodelivery techniques such as solid lipid nanoparticles, nanoemulsions, and transfersomes showed enhanced res- veratrol stability and delivery to the skin.136,307,308 Recently, microemulsions were constructed using resveratrol with particle sizes of 66–68 nm that enhanced resveratrol bioavail- ability to the skin to protect against UV radiation.309 Recently, three different nanodelivery techniques, such as solid lipid nanocarrier, nanostructured lipid carrier, and nanoemulsions, were studied for resveratrol delivery efficiency to the skin. Among them, the solid lipid nanocarrier preparation has the most enhanced resveratrol delivery to the skin.310 Analyzing resveratrol nanodelivery studies, we conclude resveratrol may be highly protective through nanodelivery techniques and may be used in the preparation of natural nanocosme- ceutical products to enhance beauty. Nanoquercetin Quercetin is another phytoactive flavonoid compound having efficiency in multiple aspects such as skin care and beauty through antioxidant activities; thereby, it enhances skin beauty and personal care.311–314 In comparison to other fla- vonoids, quercetin showed higher skin protecting efficiency and enhanced beauty due to its abundance of OH groups. This leads many researchers to analyze the multiple efficiencies of quercetin in cosmetics. However, the major drawback of quercetin applications is its stability and penetrating effi- ciency, which is solved by nanodelivery techniques. Solid lipid nanoparticle and nanostructured lipid carrier nanode- livery systems were compared for the effective delivery of the quercetin to the skin. The nanostructured lipid carrier showed higher quercetin retention in the skin membrane with a particle size of ~282 nm.138 The same research group also suggests that quercetin in the solid lipid nanoparticle prepa- ration has increased skin protection against UV radiation of human skin.253 Nanoglycerosomes were also prepared with particle sizes between 80 nm and 110 nm that enhanced skin delivery of quercetin along with its photoprotective effects against oxidative damage.222 Similarly, quercetin-rich nano- emulsions and A. satureioides nanoemulsions were prepared with nanoparticles ranging from 200 nm to 300 nm. This preparation had higher skin retention of the phytocompounds with increased skin protecting activity.164 In another study, quercetin-loaded nanocapsules were constructed with a par- ticle size of 228 nm for sustained delivery of quercetin to the skin to increase antioxidant activity.315 From these studies, we conclude that quercetin may be used in the preparation of various nanosized cosmeceuticals products with increased In te rn a tio n a l J o u rn a l o f N a n o m e d ic in e d o w n lo a d e d f ro m h tt p s: // w w w .d o ve p re ss .c o m / b y 1 2 8 .1 8 2 .8 1 .3 4 o n 0 6 -A p r- 2 0 2 1 F o r p e rs o n a l u se o n ly .

Nanogreen tea Natural green tea extract is rich source of bioactive com- pounds, such as catechin, epigallectocatechin, epicatechin, and epigallecto-3-catechin, which are powerful antioxidants widely used in skin care and beauty treatments.316–320 The individual potential of these compounds also varies in usage for development of cosmeceutical products. Green tea com- ponents have multiple skin care roles such as antiaging and prevention of UV-induced photoaging.316,320–323 The bioactive compounds readily undergo functional group loss during the exposure to environmental conditions and decrease the stability of the compounds, which limits the application of these compounds in cosmeceutical products. Nanodelivery techniques enhance the bioavailability of these compounds in cosmeceutical products, thereby enhancing their usage in the novel development of green tea-based cosmeceuticals. Recently, Montenegro324 listed group of phytocompounds usage in commercial products. Among them, green tea catechins were used in antiaging cream preparation with fullerene as the delivery agent. Fang et al325 also prepared green tea catechin liposomes with nanoparticle sizes of 130–268 nm that enhanced antioxidant activity in the skin. In another study, green tea liposomes, with a reduced particle size of ~138 nm, enhanced green tea catechins by ethanol incorporation into the liposomes for enhanced transdermal delivery.326 Similarly, green tea polyphenol nanoliposomes were developed using milk fat globule membranes and soy lipids to enhance antioxidant activity in the cell model.327 These studies suggest that green tea polyphenols can be sufficiently nanodelivered to various skin care products for their sustained beautifying effects. Nanogenistein Genistein is one of the major isoflavones found in many cereal plants and has skin protecting activities, including antioxidant, collagen synthesis, UV protection, and antiag- ing benefits.328–333 Even though genistein has skin protecting activity and enhances beauty, its sustained effect is still limited due to lower stability in cosmeceutical products. In order to enhance stability and prolong activity, nanosized delivery technologies have greater impact in cosmeceutical sectors. Genistein-loaded nanoemulsions were prepared with 250 nm sized nanoparticles and enhanced delivery of isoflavones to the skin with higher skin protecting activity.334 In another study, nanosized liposome-encapsulated genistein in nanoparticles the size of 84 nm was tested on rat skin, with or without hair.335 In addition to the nanosized liposomes, the hairs on the skin also affect the delivery of the genistein compound to the skin. Nanolycopene Lycopene is another natural phytobioactive compound with multiple applications in skin care, including antiaging and antioxidant activity.336–345 Owing to its lipophilic nature and decreased delivery to the skin, lycopene is of limited usage in skin care products. In addition to its lipophilic nature, lycopene readily undergoes degradation during light and air exposure, which further limits its usage in cosmeceu- ticals. However, nanosizing lycopene solves most of these problems and enhances its bioavailability.141,346,347 Recently, lycopene ethosomes and transfersomes were constructed in the nanosize of 153 nm and 124 nm, respectively, which enhance the bioavailability lycopene to the skin with poten- tial antioxidant activity. Further, it enhances the penetration of lycopene to the inner cell and nucleus, which could be useful in skin protection and care.348 Research focusing on nanodelivery in cosmeceutical products containing lycopene is still limited. Nanotoxicity The major concern of using nanocosmeceuticals is toxicity owing to the small size, allowing the particles to cross the membrane easily and interact with other proteins and cells. This may lead to the other effects by their subsequent meta- bolic products.349 Before applying the products, extensive clinical screening must be done, even though many reports suggest that polymers in cosmeceuticals have no deleterious effects. Further, natural products have no side effects. Exten- sive use of these compounds may also lead to side effects. Further clinical support is needed before nanotechnology proceeds to commercialization and product development. Conclusion The greater demand of the nanosized phyto-based bioactive compound usage in the development of nanocosmeceuticals for skincare-based therapy such as moisturizing, sun block, anti-aging, whitening effects along with skin health leads many researchers in search of novel nanocosemecutical- based therapy. Nanosized cosmeceuticals with phyto-based bioactive compounds retain higher amounts of bioactive compounds in the skin, are more stable, and enhance skin appeal with prolong time. Nanosized compounds range in size. Increasing the nanosize limits the penetration ability of In te rn a tio n a l J o u rn a l o f N a n o m e d ic in e d o w n lo a d e d f ro m h tt p s: // w w w .d o ve p re ss .c o m / b y 1 2 8 .1 8 2 .8 1 .3 4 o n 0 6 -A p r- 2 0 2 1 F o r p e rs o n a l u se o n ly .

The solubility types and the cos- meceutical application of phyto-based bioactive compounds determine the delivery technology for nanocosmeceutical development. Further research of their mechanisms is nec- essary to target site release from the delivery agents. This further boosts nanosized phytobioactive compound-based cosmeceutical research and skin health. Acknowledgment This work was supported by the Konkuk University in 2015.
