Actinic keratosis treatment in New Braunfels, TX is something our dermatologists at Elect Dermatology address every single week — and for good reason. Texas ranks among the highest states in the country for UV exposure, and actinic keratoses (AKs) are one of the most direct consequences of that sun-drenched lifestyle. The good news: caught early, they’re very manageable. Left alone, they can become something far more serious.
What Is Actinic Keratosis?
Actinic keratosis is a rough, scaly patch of skin caused by years of cumulative ultraviolet (UV) radiation exposure. According to the American Academy of Dermatology, AKs are considered precancerous because a percentage of untreated lesions can progress to squamous cell carcinoma — a form of skin cancer that can spread if not addressed.
AKs typically appear on areas of the body that receive the most sun exposure: the face, scalp (especially in men with thinning hair), ears, neck, forearms, and the backs of hands. They feel rough and sandpapery, almost like a patch of dry skin that never heals.
Why Texans Are at Higher Risk
Living in the Texas Hill Country means spending more time outdoors than most Americans — hiking, swimming in the Comal River, working the land, watching kids at outdoor events. All of that adds up. The EPA’s UV Index regularly hits “Very High” and “Extreme” levels in the San Antonio and New Braunfels region from April through October. Decades of that exposure leave cumulative skin damage that manifests as actinic keratoses, often beginning in a person’s 40s and 50s.
Research published in JAMA Dermatology estimates that more than 58 million Americans have at least one actinic keratosis. In sun-heavy states like Texas, that prevalence is even higher.
What Does Actinic Keratosis Look, Feel, and Act Like?
AKs can be easy to dismiss because they often look like ordinary dry skin or a minor irritation. Here’s what to watch for:
- A rough, dry, or scaly patch of skin, typically less than an inch in diameter
- Flat to slightly raised patch of skin on the top layer
- Hard, wart-like surface in some cases
- Pink, red, or brown coloration
- Itching, burning, or tenderness in the affected area
- A horn-like protrusion (cutaneous horn) in rare cases
One hallmark sign: you can feel an AK before you can see it. Running your fingers over sun-damaged skin and feeling a rough patch is a meaningful warning sign worth having evaluated.
Treatment Options at Elect Dermatology
Our board-certified dermatologists, Dr. Hockley and Dr. Stahr, tailor actinic keratosis treatment to the number of lesions, their location, and your overall skin health. Common treatment approaches include:
Cryotherapy (liquid nitrogen): The most common in-office treatment. Liquid nitrogen is applied directly to the lesion, freezing and destroying the abnormal cells. It’s quick, effective, and leaves minimal scarring on most patients. The Skin Cancer Foundation supports cryotherapy as a first-line treatment for individual, well-defined AKs.
Topical medications: For patients with multiple AKs spread across a field of sun-damaged skin, prescription creams such as 5-fluorouracil (5-FU), imiquimod, or diclofenac sodium gel treat the entire affected area — not just visible lesions, but subclinical ones that haven’t yet surfaced. This “field therapy” approach is highly effective for preventing future lesions.
Photodynamic therapy (PDT): A photosensitizing agent is applied to the skin and then activated with a specific wavelength of light. PDT is particularly effective for patients with extensive sun damage across large areas like the scalp or face. Studies in the British Journal of Dermatology show PDT achieving clearance rates of up to 90% for AKs.
Curettage and electrodesiccation: A curette (small instrument) scrapes away the lesion, followed by electrosurgery to destroy remaining abnormal cells. Useful for thick or hyperkeratotic AKs.
Chemical peels: Medium-depth peels using trichloroacetic acid (TCA) can be used to treat field cancerization — large areas of sun-damaged skin. Learn more about our chemical peel treatments in New Braunfels.
What Happens If Actinic Keratosis Is Left Untreated?
Not every AK will become cancer — estimates from the National Institutes of Health suggest that roughly 5–10% of untreated AKs may eventually progress to squamous cell carcinoma over a 10-year period. But since most people with AKs have multiple lesions — and since there’s no reliable way to predict which ones will progress — the standard of care is to treat them.
Squamous cell carcinoma that develops from an AK can typically be caught and treated successfully when identified early. Visit our skin cancer page to learn more about how we approach skin cancer treatment at Elect Dermatology.
Prevention: Protecting Your Skin Going Forward
Once you’ve had an actinic keratosis, you’re at elevated risk for more. Prevention is an ongoing effort:
- Apply broad-spectrum SPF 30+ sunscreen every morning, year-round — even on cloudy Texas days
- Wear UPF-rated clothing, wide-brim hats, and UV-blocking sunglasses when outdoors
- Seek shade during peak UV hours (10 AM – 4 PM)
- Schedule annual full-body skin exams with a board-certified dermatologist
- Avoid tanning beds entirely
