Overview of Sunlight and Skin Damage
Actinic keratoses
 Actinic Keratoses are precancerous growths caused by long-term sun exposure. These growths are usually pink, red, or, less commonly, gray or brown. They feel rough and scaly. Seborrheic Keratoses look similar to actinic keratoses. They may appear on areas of the skin that are not exposed to sunlight but are not precancerous.
