What are actinic keratoses?

Actinic keratoses (ak-TIN-ik ker-uh-TOH-sees) are rough, scaly patches on the skin. They are usually on areas of your body that get the most sun (for example, the head, neck, arms, and hands).

Who gets them?

People with fair skin who live where it is sunny or who work outside are most likely to get actinic keratoses. The patches are usually found on older people and are more common in men than in women.

How is it treated?

It is important to treat actinic keratoses, otherwise they can turn into skin cancer.

Your doctor may remove the patches by freezing or scraping them or by having you put a cream or gel on them.

Your skin may be red, sore, or swollen after treatment. This should go away after a few days.

How can I prevent actinic keratoses?

• Avoid spending a long time in the sun or using a tanning bed.

• Wear sunscreen when you are outside. The sunscreen should have a sun protection factor (or SPF) of 15 or higher. Look for “broad-spectrum” on the label.

• Wear clothing that protects your skin from the sun (for example, a hat, a shirt with long sleeves, or long pants).
