You will experience a mild sunburnt sensation for a few hours after treatment and the skin may be red for 1 to 2 days. This is a normal sign that the skin is healing at a deep level. Swelling is likely but minimal, and resolves in 2 to 3 days. As the healing process occurs, your skin may have a ‘bronzed’ appearance that lasts from 3 to 10 days, depending on the treatment level. Your skin will naturally exfoliate and may flake as if you had mild sunburn.
