Frequent or intense exposure to UV rays, usually from the sun, causes an actinic keratosis.
An actinic keratosis begins in your skin's prime layer — the epidermis. The epidermis is as skinny as a pencil line, and it provides a protecting layer of skin cells that your body frequently sheds.
Normally, skin cells among the epidermis develop in a very controlled and orderly method. In general, healthy new cells push older cells toward the skin's surface, where they die and eventually are sloughed off. When skin cells are broken through UV radiation, changes occur within the skin's texture and color, inflicting blotchiness and bumps or lesions.
Most of the injury to skin cells results from exposure to UV radiation from daylight and business tanning lamps and beds. The injury adds up over time, that the longer you pay within the sun or in a very tanning booth, the larger your probability of developing skin cancer. Your risk will increase even additional if most of your out of doors exposure happens now and then of the day or in locations where the daylight is most intense.
