Actinic keratosis is a skin condition caused by long-term sun exposure. It leads to the development of rough, scaly patches on the skin, usually on areas that receive a lot of sun exposure, such as the face, scalp, ears, neck, arms, and hands. These patches can vary in color, ranging from skin-colored to reddish-brown, and may feel rough to the touch. Actinic keratosis is a condition that has the potential to develop into skin cancer if left untreated. Treatment options include creams applied directly to the affected areas, freezing therapy, chemical peels, and light therapy. Regular skin checks and sun protection measures, such as wearing sunscreen and protective clothing, are important for managing actinic keratosis and reducing the risk of skin cancer.
