[1] [2] [3] This reaction can be striking and worrisome for patients and is important for physicians to consider this in the differential diagnosis for patients with facial swelling and a history of dermal filler treatment and COVID-19 vaccination. Previous cases of facial swelling were successfully managed using short courses of oral steroids; however, our patient's mild symptoms resolved without treatment. 4 Ultimately, the benefits of COVID-19 vaccination greatly outweigh the minute risk of cutaneous delayed inflammatory reaction; however, all physicians should remain aware of this potential reaction and provide appropriate counselling to high-risk patients.
