It is best to prevent actinic keratoses by minimizing sun exposure. Treatments for actinic keratoses include cryosurgery, scraping or burning, 5-fluorouracil cream, imiquimod (Aldara), diclofenac (Voltaren, Cataflam, Voltaren-XR, Cambia), ingenol mebutate (Picato), TCA skin peels, and photodynamic therapy.
Actinic keratoses (AKs) are small, red, rough, scaly, flat spots that feel like dry skin patches. They often occur on sun-exposed areas, such as the nose, ears, face, chest, forearms, and back of the hands. Other common names include AK, AKs, solar keratosis, precancers, and pre-skin cancers.
