Brown sun spots most often appear on your face, hands, and arms. They’re common, especially for people over 50. Most are harmless and are caused by years of being in the sun. See your doctor if they:
- Are black
- Change shape
- Have a rough border
Wear sunscreen and cover up in the sun to help prevent them. Avoid being outdoors between 10 a.m. and 2 p.m., when the sun is strongest.
