Actinic Keratosis: Symptoms, Causes, Treatment & Prevention

Welcome to our Actinic Keratosis information center, where you can learn about this common sun-related skin condition, its warning signs, causes, treatment options, and ways to protect your skin.

Actinic keratosis (AK), sometimes called solar keratosis, is a rough, scaly or discolored skin growth caused primarily by long-term exposure to ultraviolet (UV) radiation from the sun or indoor tanning. It commonly develops on areas that receive frequent sun exposure, including the face, ears, scalp, neck, hands, and lips.

Although an actinic keratosis may appear as a small or harmless-looking spot, it is considered a precancerous skin growth. Some AKs can develop into squamous cell carcinoma, a type of skin cancer. For this reason, recognizing unusual skin changes and seeking appropriate medical evaluation is important.

Actinic Keratosis Symptoms

Actinic keratoses can look different from person to person. They may appear as rough, dry or scaly patches or small bumps that are red, pink, brown, tan, gray, white, or skin-colored. Some lesions may itch, sting, burn, feel tender, or bleed.

A dermatologist can examine suspicious skin changes and determine whether they are consistent with actinic keratosis or another skin condition.

Causes and Risk Factors

The main cause of actinic keratosis is cumulative UV exposure. Repeated exposure to sunlight or indoor tanning can damage skin cells over time. People with a history of substantial sun exposure may be more likely to develop AKs.

Protecting your skin from UV radiation is an important part of reducing the risk of developing additional actinic keratoses. Dermatologists commonly recommend broad-spectrum sunscreen with SPF 30 or higher, protective clothing, shade, and avoiding tanning beds.

Actinic Keratosis Treatment

Treatment depends on factors such as the number, location, appearance, and thickness of the lesions and the individual’s medical history. Dermatological treatments may include cryotherapy, photodynamic therapy, curettage, laser procedures in selected cases, and prescription topical medications.

Because actinic keratosis can sometimes resemble other skin conditions or early skin cancer, self-treating an unexplained lesion without a diagnosis is not recommended.

Preventing Further Sun Damage

If you have had actinic keratosis, protecting your skin from additional UV exposure is especially important. Helpful habits include applying broad-spectrum SPF 30+ sunscreen, reapplying it as directed, wearing a wide-brimmed hat and protective clothing, seeking shade, avoiding tanning beds, and regularly checking your skin for new or changing lesions.

Our goal is to provide clear, useful health information that helps readers better understand actinic keratosis and make informed decisions about discussing skin concerns with a qualified healthcare professional.
