Actinic Keratosis

Actinic Keratosis is a rough, scaly, sun-induced skin patch, often precancerous, appearing on sun-exposed areas like face and hands.

Key Information

Actinic Keratosis is a rough, scaly patch on the skin caused by long-term exposure to the sun’s ultraviolet (UV) rays. It usually appears on areas frequently exposed to sunlight, such as face, ears, scalp, hands, and arms. These patches are mostly red, pink, or brown and may feel dry or itchy. Actinic keratosis is considered precancerous, as it can sometimes develop into skin cancer if not treated. People with fair skin, a history of sunburns, or continuous outdoor exposure are at higher risk. Early detection and treatment can prevent it from spreading and protect skin health
