Actinic keratosis (AK) is one of the most common precancerous skin conditions seen in dermatology today—and one of the most important to treat early. At the Dermatology Office of Dr. Ellen Turner, we focus on identifying and treating these lesions using a variety of advanced, evidence-based approaches to help prevent progression to skin cancer while maintaining excellent cosmetic outcomes.

What Is Actinic Keratosis?

Actinic keratoses are rough, scaly patches that develop on sun-exposed areas of the skin such as the face, scalp, ears, and hands. They are caused by cumulative ultraviolet (UV) damage over time.

While they may seem harmless at first, actinic keratoses are considered precancerous lesions. A percentage can evolve into squamous cell carcinoma, a common type of skin cancer, making early detection and treatment essential.

Because it is impossible to predict which lesions will progress, dermatologists recommend treating all actinic keratoses proactively.

Why Treatment Matters

Actinic keratosis is more than a cosmetic concern it is a warning sign of underlying sun damage and an increased risk for skin cancer. Treating AKs not only improves the appearance of the skin but significantly reduces the likelihood of cancer development.

At our practice, we tailor treatment plans based on the number of lesions, their location, and each patient's lifestyle and goals.

Treatment Options We Offer

Modern dermatology provides a wide range of effective therapies for actinic keratosis. Often, a combination approach delivers the best results.

Cryotherapy (Freezing Treatment)

Cryotherapy is one of the most common and effective treatments for individual lesions. Liquid nitrogen is applied to freeze and destroy abnormal cells, allowing healthy skin to regenerate. ()

Quick, in-office procedure
Ideal for isolated lesions
Minimal downtime

Topical Prescription Creams

For patients with multiple or widespread lesions, topical medications are an excellent option. These include agents such as 5-fluorouracil, imiquimod, and diclofenac.

Treat both visible and "invisible" precancerous cells
Applied at home over several weeks
May cause temporary redness or irritation as they work

Chemical Peels

Chemical peels use specialized solutions to remove damaged outer layers of skin, allowing new, healthier skin to emerge.

Effective for field treatment (larger areas)
Improves overall skin tone and texture
Helps address widespread sun damage

Photodynamic Therapy (PDT)

Photodynamic therapy is a highly effective, non-invasive treatment for widespread actinic damage. A light-sensitizing agent is applied to the skin and then activated with a specific light source to selectively destroy abnormal cells.

Treats large areas in a single session
Excellent cosmetic results
Targets damaged cells while sparing healthy tissue

Preventing Skin Cancer: Our Primary Goal

All of these therapies share a common goal: preventing the progression of actinic keratosis into skin cancer. By addressing both visible lesions and underlying sun damage, we help reduce long-term risk while restoring healthier skin.

Advanced, Non-Surgical Skin Cancer Treatment

For patients diagnosed with certain types of skin cancer, we also offer advanced treatment options beyond traditional surgery.

One of the most innovative technologies available at the Dermatology Office of Dr. Ellen Turner is Sensus Superficial Radiation Therapy (SRT).

Non-invasive
Non-surgical
Non-scarring

SRT uses low-dose radiation to precisely target cancerous cells without cutting the skin. This makes it an excellent option for patients seeking effective treatment with minimal discomfort and superior cosmetic outcomes.
