Often this area has been exposed to the sun over a long period of time. Tender, thickened, ulcerated, or enlarging actinic keratoses should be treated aggressively. Asymptomatic flat keratoses may not require active treatment but should be kept under observation.
During photodynamic therapy, a solution is applied over the lesion and the affected skin. The area is then exposed to a light source that activates the photosensitizing agent to destroy the precancerous cells. Certain topical treatments such as 5-fluorouracil (Carac, Efudex, Fluoroplex, Tolak) cause inflammation and destruction of the lesions. Other topical treatments include imiquimod (Aldara, Zyclara) and ingenol mebutate (Picato). Your doctor may be able to diagnose an AK simply by looking at it.
How is an actinic keratosis treated?
Age is a risk factor as is having fair, light-colored skin. But the incidence of skin cancer is on the rise among younger people, so it is possible for AK to occur in people in their 30s and 40s. People with olive or darker-colored skin can also develop skin cancer. Use of this site constitutes acceptance of Skinsight’s terms of service and privacy policy.

What are the risk factors for actinic keratosis?
Without treatment, AK can lead to a type of skin cancer called squamous cell carcinoma. It most likely appears on areas of skin often exposed to the sun. These can include the face, ears, bald scalp, neck, backs of hands and forearms, and lips.
Don’t miss your chance!
Even when the medication causes a skin reaction, which indicates that it’s working, you’ll need to keep applying the medication. If you have one or a few AKs, a procedure that your dermatologist can perform during an appointment may be the preferred treatment. At-home treatment is often recommended for patients who have several AKs. Contact your provider if you see or feel a rough or scaly spot on your skin, or if you notice any other skin changes. Actinic keratosis is a small, rough, raised area on your dermatology and skin cancer center skin.
