Actinic keratosis is commonly treated with cryotherapy (freezing with liquid nitrogen), medicated creams like 5-fluorouracil or imiquimod, chemical peels, photodynamic therapy, or laser treatment, all of which work by destroying abnormal sun-damaged skin cells so healthy skin can regrow. Early removal is important because some actinic keratoses can slowly develop into squamous cell skin cancer if left untreated. During recovery, patients may experience redness, crusting, peeling, mild pain, or temporary skin discoloration, usually healing over days to weeks depending on the treatment used. Follow-up care is important if lesions return, new rough spots appear, or there is persistent bleeding, pain, or rapid growth, since ongoing sun damage increases the risk of recurrence and skin cancer.
