Hyaluronic acid dermal fillers are a very popular choice for patients wanting to undergo non-invasive facial rejuvenation. Its prevalence is predicted to continue to rise.

To our knowledge, this is an unusual case of hypersensitivity reaction of eight-month latency. Although the aetiology warrants further research, the author suggests utilisation of a four-week time window between dermal filler injections and COVID-19 vaccination.
