Actinic Keratosis (AK)

AKs are dry, scaly patches that form on sun exposed areas of the skin, such as the scalp, face, and forearms. Actinic keratoses are considered precancerous because they have the potential to become a type of skin cancer called squamous cell carcinoma. Treatment options include treatment with liquid nitrogen, photodynamic therapy with blue light, and/or topical medications.
