What are brown spots?

Brown spots, also called liver spots or age spots, are caused by sun exposure. They occur most often on the face, the backs of the hands, and other areas often exposed to sun. They are sometimes tan-colored rather than brown and are medically known as lentigines.

Melasma is another type of brown spot. Melasma is caused by sun exposure and is more common in women who are pregnant or on oral contraceptives. These types of brown spots are harmless.

In rare cases, brown spots are caused by certain hereditary illnesses. Talk to your dermatologist for more information about brown spots.

Hyperpigmentation is an overproduction of melanin in a certain area, as a response to UV exposure. Hypopigmentation is another sign of sun damage that results in white spots, like confetti sprinkled on the skin. This happens when the sun basically fries the melanocytes in that area and they can no longer produce pigment at all - leaving those spots especially vulnerable to sun damage.
