Does the Sun Cause Moles?

Most moles occur on parts of the body that are exposed to the sun (ultraviolet radiation), and the number of moles an individual has may increase after extended time in the sun. Moles usually begin to occur in childhood. These moles are called acquired melanocytic nevi (and include the subtype epidermal nevus).

Do Sun moles go away?

Moles often appear and disappear according to hormonal changes. Pregnancy can make them darker, puberty can multiply them, and their numbers are likely to diminish in old age. However, moles always stay for years, unlike freckles, which tend to be smaller and paler and can temporarily pop out after sun exposure.

Why do I get moles from the sun?

What Causes a Mole? Moles occur when cells in the skin grow in a cluster instead of being spread throughout the skin. These cells are called melanocytes, and they make the pigment that gives skin its natural color. Moles may darken after exposure to the sun, during the teen years, and during pregnancy.
