This hyperpigmentation develops as a result of melanocyte activity by the combination of genetic predisposition located on the basal layer and sun exposure. Glycolic acid and vitamin C are widely used as a depigmentation agent. The component of vitamin C is unstable, hence, it is often used more effective when it binds to other depigmentation agents, such as glycolic acid to develop better depigmentation
