Melasma: why sun protection is the whole treatment

Melasma is triggered by ultraviolet light, visible light and heat, which is why treatment plans that ignore daily protection consistently relapse.

Prescription topicals and carefully selected procedures can accelerate clearance, but maintenance is lifelong.
