Actinic Keratosis

What is Actinic Keratosis?

An actinic keratosis (ak-TIN-ik ker-uh-TOE-sis) is a rough, scaly patch on the skin that develops from years of sun exposure. It's often found on the face, lips, ears, forearms, scalp, neck or back of the hands.

Actinic keratoses vary in appearance. Symptoms include: Rough, dry or scaly patch of skin, usually less than 1 inch (2.5 centimeters) in diameter. Flat to slightly raised patch or bump on the top layer of skin.

Complications. If treated early, actinic keratosis can be cleared up or removed. If left untreated, some of these spots might progress to squamous cell carcinoma. This is a type of cancer that usually isn't life-threatening if detected and treated early.

Actinic keratoses are very common, and many people have them. They are caused by ultraviolet (UV) damage to the skin. Some actinic keratoses can turn into squamous cell skin cancer. Because of this, the lesions are often called precancer.

Use sunscreen on all exposed skin. And use lip balm with sunscreen on your lips. Apply sunscreen at least 15 minutes before going outside and reapply it every two hours — or more often if you're swimming or sweating. Sunscreen is not recommended for babies under 6 months.

Standard options include cryotherapy, curettage, or surgical excision. These therapies are effective for targeting specific visible lesions.
