Prevention using sunscreen is the best home remedy for actinic keratosis, as it is a condition that develops over a long period of time due to sun exposure. Actinic keratosis, which causes rough scaly patches on the skin and potentially develops into skin cancer, should be treated by a physician, according to Mayo Clinic.
Actinic keratosis normally resolves without treatment, but it returns again with exposure to the sun, explains Mayo Clinic. As it is not possible to tell which patches may or may not turn into cancer, all actinic keratoses are normally removed. Cryotherapy or freezing of the lesions on the skin causes them to blister and peel. As the skin heals, new skin develops and emerges. A doctor also uses curettage or scraping of the damaged cells to remove actinic keratosis. This is done with a special tool and results in scarring or discoloration of the skin.
Other treatments for actinic keratosis include medications that are applied to the skin such as Aldara, Fluoroplex and Voltaren, states Mayo Clinic. Photodynamic therapy is also used to treat actinic keratosis. During this procedure, a medication is applied to the skin that makes it sensitive to light. A special laser is used to destroy damaged skin cells. Patients may experience redness, swelling or a burning sensation in the treated area.
