This evaluate aims to collate present-day findings about the pathogenesis of melasma. In the next sections, we reinforce the concept of melasma to be a multifactorial disorder, and discuss a number of areas that interact in its pathogenesis, pertaining to genetics, photo voltaic radiation, endocrine stimuli, oxidative status, and morphofunctional alterations.
