The best way to prevent Melasma is to limit skin exposure to the sun. If you go out in the sun, take these preventive measures:
- Wear a hat with a brim to shade and protect your face.
- Apply sun block , such as the selection from Alumier MD that protects you against both ultraviolet A and ultraviolet B radiation. The sunscreen should have a sun protection factor (SPF) of at least 30.
