Actinic Keratoses are skin growths that produce rough skin spots that persist on the skin and occur due to prolonged exposure to the sun. This is a prevalent condition and can be treated at Skin Dermatology by our board-certified dermatologist.

How Do Actinic Keratoses Develop?

Years of being in the sun can lead to damage to the skin cells. Skin cells called keratinocytes can begin to form abnormally, which leads to actinic keratoses. This change leads to scaly skin and discoloration in small patches.

What Are the Symptoms of Actinic Keratosis?

An actinic keratosis is often a small spot on the skin that has changed color and is scaly or rough. The color can be brown, tan, gray, white, or even pink. These spots will often appear in areas with significant sun exposure over a lifetime, including the hands, arms, ears, scalp, face, and neck.

Are Actinic Keratoses Dangerous?

In some cases, these spots can lead to squamous cell carcinoma (SCC), a common form of skin cancer. Only about 5-10% of actinic keratoses progress to SCC, but it is always essential to have them examined by a dermatologist.

Before Treatment for Actinic Keratoses

Prior to your treatment of actinic keratoses, a dermatologist will examine the area. This may also include a biopsy where a small sample is taken and sent to a lab for review. This is done to rule out squamous cell carcinoma.

Your Treatment Options

There are a few different methods for treating actinic keratoses, depending on the individual patient's needs.


This involves removing the lesion by cutting it out. Because these spots are small, this is a simple procedure, though in some cases, it may require stitches.


In this method, the skin is sprayed with a solution of liquid nitrogen to freeze the cells. This solution causes the lesion to scab and fall off within a few days.


This technique burns the lesion using an electric current.

Topical Treatments 

There are also some topical treatments available that the doctor may recommend. 


This technique involves using a tool to scrape away the lesion.
