About

Melasma is a common, acquired, esthetically disfiguring hypermelanosis of the face. Melasma is considered a disappointing challenge when treatment options are addressed. Diverse treatment modalities such as retinoic acid, hypo-pigmenting agents like hydroquinone, azelaic acid, and kojic acid, chemical peels, microdermabrasion, and lasers have been tried for the treatment of melasma. There is no universally proven therapy that induces and maintains remission of the condition. Q-switched: Nd YAG laser toning and platelet rich plasma (PRP) are promising treatments for melasma.The aim of this work is evaluate the efficacy and safety of combined PRP and Q-switched: NdYAG laser in the treatment of melasma using clinical assessment, in addition to assessment of Melanin Index and Erythema Index.
