What Is Actinic Keratosis?
If you've spent a lot of time in the sun, you might be noticing some changes in your skin. Actinic keratosis (AK), also known as solar keratosis, is a scaly, crusty, rough lesion that grows on the skin in areas exposed to sunlight. It often appears on the face, lips, scalp, ears, shoulders, and other areas regularly exposed. Most often, the areas affected will present with more than one lesion. These lesions develop slowly over time and may vanish and reappear. They are often itchy, uncomfortable, and eventually become inflamed. A thorough skin evaluation with Dr. Adam Aldahan and our experienced team at Palm Beach Dermatology will include analyzing skin lesions clinically and using dermoscopy. This skin ailment is considered precancerous, as untreated lesions can develop into cancerous cells and lead to various types of skin cancer, including squamous cell skin cancer. Elimination of the lesions will most likely be recommended but will be discussed during your examination. Schedule a consultation at our Boca Raton, FL practice to learn more about our treatment options.
How Is Actinic Keratosis Treated?
Prompt intervention and treatment are imperative to prevent an isolated actinic keratosis (or keratoses) from developing into skin cancer. The treatment method chosen depends on several factors, including your age, health, skin type, the size and growth characteristics of the lesion(s), and the location of the treatment area. Common treatment choices include:
- Cryosurgery: This involves applying liquid nitrogen to freeze and destroy the lesions.
- Electrodesiccation and curettage: This procedure scrapes away actinic keratosis lesions and uses heat to cauterize the area, reducing the risk of recurrence.
- Photodynamic therapy: This approach utilizes light-sensitive medication that targets and destroys abnormal cells when exposed to special light. It's especially effective in treating actinic keratosis in large areas.
- Topical chemotherapy: Medications, like fluorouracil or a combination of fluorouracil and calcipotriene, are applied to the skin to reduce the lesions and prevent scarring. This topical treatment can take several weeks to show results.
- Imiquimod: A topical immune-response stimulator that encourages the body's immune system to attack cancerous cells and actinic keratosis lesions.
- Chemical peels: Acidic solutions, like salicylic acid, are applied to the skin, causing the top layer of skin to peel away, allowing new, healthier skin to form.
In some cases, a squamous cell carcinoma may develop from untreated actinic keratoses, and additional treatments may be required. Long-term follow-up is essential to monitor for new or recurring lesions.

What Are the Causes of Actinic Keratosis?
Excessive, long-term sun exposure is the primary cause of actinic keratosis, especially in individuals with fair skin who are more sensitive to UV damage. Older adults face a higher risk, as sun-related skin changes accumulate over time. While not every actinic keratosis becomes cancerous, some can progress into more serious conditions if left untreated. Protecting your skin is essential—apply broad-spectrum sunscreen, wear sun-protective clothing, and limit exposure during peak sunlight hours. If you notice persistent rough patches, scaly spots, or dark crusts that don’t heal, it’s important to seek professional evaluation. After using any topical treatments, remember to wash your hands and continue wearing protective clothing to help prevent future damage.
How is Actinic Keratosis Diagnosed?
At Palm Beach Dermatology in Boca Raton, FL, Dr. Aldahan begins the diagnosis with a thorough visual skin exam to assess any suspicious areas. In many cases, actinic keratosis can be identified by appearance alone. However, if a lesion looks unusual or raises concern, a skin biopsy may be performed to rule out skin cancer. With his expertise in diagnosing and managing precancerous conditions, Dr. Aldahan ensures you receive accurate answers and a treatment plan tailored to your needs.
