Hello and welcome to healthcaremagic. Chemical peeling is a very popular method of treatment for hyperpigmentary conditions of the skin. Usually a series of sessions are performed for hyperpigmentation of the skin. Results depend on the kind of peel and the underlying condition,to some extent. E.g while post acne hyperpigmentation responds very well to chemical peeling, Melasma may respond partially OR even if faded almost completely, may recur once the chemical peeling is discontinued. Therefore, while chemical peeling gives good results, they should be followed up with a maintenance regime/cream so that the results are not reversed after the peeling is discontinued,particularly for melasma. Sunscreens are an essential part of pigmentation treatment and it is advisable to use a broad spectrum sunscreen, throughout the day. regards
