What is Actinic Keratosis?
Actinic keratosis (AK) is a scaly, rough, crusty lesion that forms on the skin in areas exposed to the sun. It most often appears on the lips, face, scalp, ears, shoulders, and other areas frequently exposed. Typically, the areas of skin affected will have more than one lesion, so the plural of this condition is known as actinic keratoses. These lesions develop slowly over time and may disappear and reappear, and be itchy, uncomfortable, and become inflamed. During a thorough skin assessment, our board-certified dermatologists at Snyder Dermatology will analyze the lesion, sometimes utilizing dermoscopy. Even though this skin condition is considered precancerous, it can be a cause for concern if not treated and could develop into a skin cancer. Removal of the lesion will most likely be recommended and discussed during the examination.
"I had terrible acne problems for the first time in 22 years and decided to try out this clinic. Right away the appointment was booked within the week and in my first consultation they offered me a long term plan and short term solution for the pain. The clinic is very clean and the staff is very friendly, they definitely make you feel at ease. On top of everything the doctors referred me to specific pharmacies that could offer me lower prices for the medications. My acne mostly cleared within a month but follow up visits made sure It cleared completely and made sure I was comfortable with the treatment and long term use."- D.C. / Google / Oct 26, 2019

"I've been seeing Dr. Snyder for the past ten years. The first time was when I was splitting my time between Los Angeles and Austin while in graduate school. I had a major eczema problem on my skin. I had no clue that the skin problem was from the fumes of an art project I had been creating for a client, till I discussed the specifics of my days before the out break with Dr. Snyder. She was like one of those damn ghost whisperers, walking me through my days. When she nailed the source, she simply explained to me the problem was from the fumes of the chemicals I was working with at the time (industrial resin and a catalyst). She prescribed a steroid and gave me a skin routine, my eczema went away within a week. Amazing! She is still my "go to" dermatologist for other issues I have had over the past few years. Yes, I travel from LA to Austin to see her. She's that good. Keep in mind that she is straightforward and to the point but awesome!"- J.S. / Yelp / Oct 02, 2019
"Dr. PARKER is an incredible dermatologist. I called on Tuesday morning in a panic because of an allergic reaction - she fit me in later that day. Not only did she work quickly to diagnose the problem, but she prescribed medications that fit my difficult and specific allergies. I called on Wednesday to check in and she spoke on the phone with me personally, and is meeting with me for a follow-up as well. 10/10 doctor all around- truly cares about her patients. Would recommend her to everyone reading this!!!! Best dermatologist experience I've had- and I've seen a lot of them."- C.C. / Yelp / Aug 22, 2019

Chronic sun exposure is the main cause of actinic keratosis and it is more prevalent in older individuals from years of sun damage. While only a small percentage of AKs turn into skin cancer, it's important to understand what this skin condition looks like and how to treat it. In most cases, this skin condition shows up as lesions that look red and scaly, as well as bumps and tan crusts that show up in multiple clusters that do not heal. When the condition first appears, it may feel only like rough texture on the skin. Sometimes this area will itch and become irritated. Over time, especially if it is exposed to more sun, the patchy area will turn red, scaly, bumpy, and inflamed and continue to grow. The more keratoses that exist, the chances of developing skin cancer increases. So any of these warning signs should be checked by a board certified dermatologist so that treatment can be provided, and future prevention discussed.
How to Treat Actinic Keratosis
Early intervention and treatment is important so that an isolated actinic keratosis or keratoses does not become skin cancer. The treatment option recommended will vary by patient depending on numerous factors such as the patient's age and health, color of skin, how widespread the condition is, growth characteristics of the lesion(s), location, etc. Some common treatment options include:
Cryosurgery is the method of taking liquid nitrogen and using it to destroy lesions (such as actinic keratosis). The procedure is performed in our office and uses liquid nitrogen via a spray to remove the growth. Most patients are able to leave the office shortly after the procedure.
- Electrodesiccation & Curettage
This is a procedure removes skin lesions by scraping the skin down to the unaffected layer. The procedure eliminates the lesion, as well as underlying tissue and/or pre-cancerous cells that may exist. This treatment causes minor scarring, but it remains a proven and effective substitute for surgery and is used in cases where the growth only affects the top layers of the skin. This is commonly used for hypertrophic (thick) actinic keratosis.
When actinic keratoses are widespread, prescription topical creams, gels or solutions may help improve the area and reduce symptoms, this is also called field therapy. These medications can be especially helpful when combined with other therapies, as they treat both the visible lesions and those not yet seen by the naked eye. A common medication used for treatment is 5-fluorouracil (5-FU), which is an FDA-approved topical chemotherapy. This medication is gently rubbed onto the affected area and lesions twice daily for several weeks. Other medications include Imiquimod cream, diclofenac, Picato® (ingenol mebutate), and other variations of fluorouracil that help reduce the lesion counts with a reduced incidence of scarring and in skin cancer.
- Chemical peels
Our dermatology office offers numerous chemical peel variations that can help remove the unhealthy surface layer and superficial lesions. The chemical agent most commonly used is trichloroacetic acid (TCA). This is applied to the skin, causing the top layers to peel and slough off. New skin regenerates and replaces the damaged tissue.
