If you have an actinic keratosis (AK) on your skin, you are not alone. AK is one of the most common skin conditions treated by dermatologists, with more than 40 million Americans developing these precancerous growths each year. Understanding what causes AK, how to recognize it, and why early detection is important can help protect your skin health.
What Causes Actinic Keratosis?
AKs develop due to prolonged exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Many people do not consistently protect their skin with sunscreen, clothing, or shade, allowing the sun’s harmful rays to cause cumulative damage over the years. While the body can repair some of this damage, ongoing exposure without protection leads to skin changes that may result in precancerous growths.
Where Do Actinic Keratoses Appear?
AKs commonly develop on areas of the skin that receive frequent sun exposure, including:
- Face
- Ears
- Scalp (especially in individuals with thinning hair)
- Hands
- Neck
- Lips
When an AK forms on the lips, it is known as actinic cheilitis. People who have used tanning beds or sunlamps are also at increased risk of developing AKs due to the high-intensity UV radiation these devices emit.
Recognizing Actinic Keratosis
AKs may not always look alarming at first. They can resemble age spots, pimples, or rough, scaly patches of irritated skin. On the lips, they may appear as persistent dryness or chapping that doesn’t heal. Paying close attention to new or changing skin growths is essential, especially if you have a history of sun exposure without protection.

The Importance of Early Detection
While many people with AKs feel perfectly healthy, these precancerous growths should not be ignored. Some AKs can develop into squamous cell carcinoma, a type of skin cancer. By identifying and treating AKs early, you can prevent the potential progression to skin cancer and maintain healthier skin.
If you notice new rough patches, persistent dry spots, or unusual skin changes, schedule a consultation with a board-certified dermatologist. Regular skin checks and sun protection measures can help keep your skin healthy and reduce your risk of developing actinic keratosis.
