About Actinic Keratosis
Actinic keratosis (AK) is a scaly, rough, crusty lesion that forms on the skin in areas that are exposed to the sun. Older men and women are at high risk to develop AK. It most often appears on the lips, face, scalp, ears, shoulders, and other areas frequently exposed. Normally, the areas of skin affected will have more than one lesion. Because of this factor, the plural of this condition is known as actinic keratoses. They are often itchy, uncomfortable, and become inflamed.
During a thorough skin assessment at Advanced Dermatology in Katy, League City, Pearland, or Sugar Land, TX, we will analyze the lesion to see if it is precancerous. Removal of the lesion(s) will most likely be recommended and discussed during your examination.
Usually called "chicken skin," keratosis pilaris is a benign skin condition that presents as rough patches, tiny bumps, and dry skin on the upper arms, cheeks, thighs, or buttocks. Generally, these bumps don’t itch or hurt since they are simply a result of excess keratin on the skin. Keratin is a hard protein that acts as a protection of the skin from infections. This keratin will clog and block the hair follicles, which then results in small bumps.
Seborrheic keratosis (SK) lesions can also appear as raised bumps that are white, tan, brown, and black. The difference between AK and SK is that SK lesions are not cancerous.

Actinic Keratosis Causes
Lengthy sun exposure is the root cause of actinic keratosis, and it is more prevalent in older men and women 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. Typically, this skin condition shows up as lesions that are red and scaly, as well as bumps and dark crusty areas that show up in numerous clusters. The biggest sign of AK is that the lesions do not heal.
Actinic Keratosis Symptoms
When AK first appears, it may only feel like rough texture on the skin. Sometimes this area will itch and feel 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 they spread, the greater the chances of developing skin cancer. Any warning sign should be checked as soon as possible by a professional so treatment can be provided and future prevention strategies discussed.
Actinic Keratosis Treatment Techniques
Your recommended AK treatment option will vary on numerous factors, such as your age, health, skin color, the severity of the condition, growth characteristics of the lesion(s), location, etc. Advanced Dermatology offers:
- Chemical peels
Medical-grade chemical peels administered by our practitioners can reduce the top layer of the AK skin to stimulate new growth and revitalize the damaged tissue.
The freezing method of cryosurgery uses liquid nitrogen to destroy lesions.
- Electrodesiccation and curettage
We can remove AK skin lesions with electrodesiccation and curettage by scraping the skin down to a healthy layer.
We can prescribe medications to reduce the appearance and volume of lesions and incidences of scarring.
