Expert recommendations on supportive skin care for non-surgical and surgical procedures.

A thorough knowledge of non-surgical procedures (laser, peelings, injections, threads) and surgical procedures (combined surgeries and skin grafts), including contraindications and potential risks and side effects, (e.g. infection, hypopigmentation, hyperpigmentation, and scarring) is essential to be able to reduce their incidence and ensure the patient receives the most benefit from the procedure. Individuals with darker skin and of high Fitzpatrick phototype are at higher risk of dyschromias, notably melasma and post-inflammatory hyperpigmentation, which may be treated using aesthetic procedures but may also arise as a complication of some procedures. A group of experts in cosmetic surgery and dermatology reviewed the published literature and discussed recommendations for optimizing outcomes with practical advice on supportive skincare before, during and after non-surgical or surgical procedures. A broad-spectrum sunscreen with a high sun protection factor against UVB and high protection against UVA, especially long UVA, is essential for all treatment modalities for the prevention and potential improvement of pigmentation disorders. Supportive skin care management to prepare, cleanse and protect the skin and post-procedure skin care with healing and anti-inflammatory ingredients are recommended to speed up regeneration and wound healing whilst minimizing scarring and downtime. Additionally, adjunctive skin care to procedures with antioxidant, anti-ageing and lightening properties may enhance skin benefits.

Good tolerance of hyaluronic acid filler injections during the COVID-19 pandemic.

BACKGROUND: The aim of our study was to identify and evaluate the complications related to hyaluronic acid during the COVID-19 pandemic. METHOD: Twelve dermatologists participated in this study. A cohort and a non-cohort follow-up were ensured. RESULTS: (1) Cohort follow-up: 1041 patients. 8% had a COVID-19 infection, 27% had received COVID-19 vaccination. 2% had immediate side effects (edema, erythema, bruising). 0.5% had delayed side effects (two inflammatory nodules, one nodule without inflammation, one edema). None of these side effects occurred in the context of infection or COVID-19 vaccinations. (2) Non-cohort follow-up: 7900 syringes used. Two early side effects (inflammatory edema) were reported, of which one occurred 15 days after vaccination. Two cases of delayed side effects such as inflammation on the injected area and inflammatory nodules occurred of which one was in the context of vaccination and one during COVID-19 infection. We estimate the frequency of complications possibly attributable to the disease or to the COVID vaccination to be 0.06% in our population. DISCUSSION: Complications of HA injections in the context of COVID-19 disease or vaccination appear to be very rare but the frequency could be underestimated because of the low rate of vaccination/infection in our population. Our study shows a very good tolerance of hyaluronic acid injections during the COVID-19 pandemic.
