(HealthDay News) — Liver spots are flat, dark areas of pigment that appear on the skin — often on areas exposed to the sun.

The likelihood of getting such spots tends to rise as we age, says MedlinePlus.

Common after age 40, the painless spots typically appear on the face, forearms or shoulders.

While not dangerous to your health, they may resemble signs of skin cancer, and should be evaluated by a health care professional, MedlinePlus advises.
