Melasma treatment focuses on lightening dark patches of skin and preventing them from coming back. Common treatments include topical creams like sunscreen, hydroquinone, retinoids, and azelaic acid, which help reduce pigmentation. Procedures such as chemical peels, laser therapy, and microneedling may also be used in some cases. Consistent use of broad-spectrum sunscreen is essential, as sun exposure is the main trigger for melasma.
