What is an Actinic Keratosis and How Can You Treat It?

Did you know that skin is considered an organ? Actually, your skin is the largest part of an entire system of organs called the integumentary system that protect the outside of your body from both internal and external damage!

Just like any other organ, there’s always the potential for issues to arise with your skin. One of the most common skin problems people face is called an actinic keratosis. Not sure what that is? Don’t worry— our expert dermatologists are here to keep you informed! 

What is an actinic keratosis?

An actinic keratosis (AK) is a scaly, precancerous lesion that forms on your skin. These lesions are caused by chronic and prolonged exposure to UV radiation, primarily from the sun. AKs usually develop in areas that are most often exposed to the sun’s rays—your scalp, ears, face, arms, etc.

How serious is an actinic keratosis?

If left untreated, AKs can develop into squamous cell carcinoma (SCC), one of the most common forms of skin cancer. Although having these lesions doesn’t necessarily mean you will develop cancer, it is important to note that a majority of SCC cases start off as AKs. Once you have one, more AKs will continue to develop on your skin, further increasing your risk for skin cancer.

How are actinic keratoses treated?

There are several methods available to treat an actinic keratosis, depending on the number you have, where they are, and their severity.

Cryotherapy

If you only have a few moderate AKS, your dermatologist can destroy them with liquid nitrogen. The treated area will start to blister and peel within a few days, revealing new, healthy skin underneath.

Chemotherapy Cream

For thicker, more severe actinic keratoses, a topical cream containing chemotherapy drugs can be applied to the affected area. After extended use over a period of time, chemotherapy cream can be an effective AK healing method.

Photodynamic Therapy

For especially widespread and serious cases of AKs, your dermatologist might turn to photodynamic therapy. This type of treatment involves applying medication to the affected area, allowing it to sit and concentrate in the precancerous cells for one to two hours, and then putting them under a specific wavelength of light to activate the medication and destroy them.
