Actinic Keratosis Treatment in San Juan Capistrano, CA
Rough, scaly spots on sun-exposed skin are more than a cosmetic nuisance. These patches, known as actinic keratoses, are precancerous growths that can develop into skin cancer if left untreated. At HK Dermatology in San Juan Capistrano, CA , our dermatology team identifies and treats actinic keratoses early, using proven therapies that clear existing spots and help protect your skin from future damage.
Request an AppointmentWhat Is Actinic Keratosis?
Actinic keratosis (AK), also called solar keratosis, is a rough, scaly patch of skin caused by years of cumulative ultraviolet (UV) exposure from the sun or tanning beds. AKs are considered precancerous because a portion of them can progress into squamous cell carcinoma, a common form of skin cancer. Where there is one AK, there are often others developing under the surface, which is why dermatologists treat both the visible spots and the surrounding sun-damaged skin.
AKs are most common in adults over 40 with fair skin, light eyes, or a history of frequent sunburns, as well as people who spend a lot of time outdoors. In sunny Southern California, they are among the most frequent concerns our team sees.
Signs and Symptoms
- A dry, rough, sandpaper-like patch that is often easier to feel than see
- Flat or slightly raised spots that may be pink, red, tan, or skin-colored
- Scaly or crusty areas that may itch, burn, or bleed when rubbed
- Patches that seem to heal and then return in the same place
- Spots on sun-exposed areas such as the face, ears, scalp, lips, neck, forearms, and backs of the hands
When an AK develops on the lower lip, it is called actinic cheilitis and may appear as persistent dryness, cracking, or a blurred lip border. Because some skin cancers look similar to AKs, any spot that grows, becomes tender, or bleeds should be evaluated promptly.
Treatment Options for Actinic Keratosis
The best treatment depends on how many AKs you have, where they are located, and your overall skin health. At HK Dermatology, Dr. Jeffrey Klein and our providers offer several proven options:
- Cryotherapy: Liquid nitrogen freezes individual lesions so they peel away within days to weeks.
- Topical field therapy: Prescription creams such as fluorouracil or imiquimod treat both visible AKs and early, unseen damage across a larger area.
- Photodynamic blue light therapy: A light-activated solution is applied to the skin and then activated with blue light to destroy precancerous cells.
- Chemical peels: Medical-grade chemical peels remove damaged outer layers of skin and improve overall texture.
- Laser resurfacing: Fractional laser resurfacing can treat widespread sun damage while also improving fine lines and tone.
- Curettage and other procedures: Thicker lesions may be scraped away or removed and sent for testing.
Preventing New Actinic Keratoses
Daily broad-spectrum sunscreen with SPF 30 or higher, wide-brimmed hats, sun-protective clothing, and avoiding midday sun dramatically reduce the risk of new AKs. Our office carries custom-formulated sunscreens designed for daily use. Regular full-body skin exams are also important, since patients with AKs have a higher lifetime risk of basal cell carcinoma, squamous cell carcinoma, and melanoma.
Sun damage also causes brown spots and uneven tone. Once precancerous spots are treated, cosmetic options such as an IPL photofacial can help restore a more even complexion. If you also have tan, waxy growths, you may be dealing with seborrheic keratosis, a harmless condition that is often confused with AKs.

Actinic Keratosis FAQs
Is actinic keratosis cancer?
Actinic keratosis is precancerous, not cancer. However, some AKs can progress into squamous cell carcinoma if left untreated, so dermatologists recommend treating them.
What does actinic keratosis look like?
AKs usually appear as rough, dry, scaly patches that may be pink, red, tan, or skin-colored. They are often easier to feel than to see and appear on sun-exposed areas like the face, scalp, ears, and hands.
Does treatment for actinic keratosis hurt?
Most treatments cause only mild, temporary discomfort. Cryotherapy may sting briefly, and topical creams or photodynamic therapy can cause redness and peeling for several days as the skin heals.
Will actinic keratosis go away on its own?
Some AKs may fade temporarily, but they often return, and new ones commonly develop. Because there is no way to predict which AKs will progress, treatment is the safest approach.
How can I prevent actinic keratosis?
Wear broad-spectrum SPF 30 or higher sunscreen daily, reapply when outdoors, wear hats and protective clothing, and avoid tanning beds. Regular skin exams help catch new spots early.
How often should I get skin checks if I have AKs?
Most patients with a history of actinic keratosis benefit from skin exams every six to twelve months. Your provider will recommend a schedule based on your sun damage and history.
Is AK treatment covered by insurance?
Because actinic keratosis is a precancerous condition, treatment is typically considered medically necessary and is often covered by insurance. Check our insurance page or call our office for details.
