# Melasma

## 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.
