Quick Summary

Melasma is a patchy brown or gray-brown discoloration pattern, often on the cheeks, forehead, upper lip, or jawline. It is different from a single acne mark or sun spot.

Causes

UV exposure, visible light, heat, hormones, pregnancy, and genetics can influence melasma. Because it can be stubborn and recurrent, clinician guidance and daily broad-spectrum sun protection matter.

How cosmetic skincare can help

A conservative routine focuses on comfort, consistency, and avoiding obvious triggers. Helpful ingredients or products should be selected for the visible pattern and skin tolerance, not used as proof of a diagnosis.

When to Seek Care

Pain, swelling, pus, bleeding, rapidly spreading changes, severe itch, eye symptoms, scarring, or persistent uncertainty should be checked by a clinician.
