What Causes Age Spots?
Age spots are the result of an excess production of melanin, or skin pigment. Doctors don't always know why age spots develop. Skin aging, sun exposure, or other forms of ultraviolet (UV) light exposure, such as tanning beds, are all possible causes. You're most likely to develop age spots on the areas of your skin that receive the most sun exposure, including:
- Your face
- The back of your hands
- Your shoulders
- Your upper back
- Your forearms
