Visible light (400–700nm), which contributes to 45% of solar radiation, contributes to skin darkening and worsening of dyschromias, particularly in individuals with Fitzpatrick skin phototypes III and higher.

The pathogenesis of melasma is incompletely understood, which poses a challenge for disease management. Causative factors include genetics, ultraviolet (UV) radiation, cosmetics, pregnancy, hormonal therapy, phototoxic drugs, and various medications.
