AKs can disappear without treatment; however, this condition typically returns if the individual is exposed to the sun frequently. 

Due to the fact that it can’t be determined if AKs will develop into SCC, all AKs are treated as a precaution. Four common treatments include: 

• Cryotherapy (freezing through liquid nitrogen): This is the most common treatment for AKs. After treatment, the treated area will become blistered and begin to peel after a couple of days. Once your skin is healed, new skin will appear.This treatment’s side effects could include blistering, scarring, skin texture and skin tone changes, and possible infection.
• Medications: If a patient has multiple AKs, a dermatologist may prescribe a cream for the areas such as fluorouracil cream, imiquimod cream, ingenol mebutate gel or diclofenac gel. Side effects of this treatment could include redness in the skin, scaling or a burning sensation. 
• Curettage (scraping of the skin): If your dermatologist recommends scraping off the skin, they will use a device called a curet, which is then followed by electrotherapy. This will remove any damaged cells. During this treatment, you will be given an anesthetic. Side effects of this treatment could include possible infections, scarring of the skin and skin discoloration. 
• Photodynamic therapy (PDT): PDT is a non-invasive therapy that uses multiple light treatment sessions in conjunction with a photosensitizing agent. PDT treatment will be repeated six weeks after the first treatment.This treatment’s side effects could include redness and swelling of the skin and a burning sensation during therapy.
• Chemical peel: This is a medical-grade chemical peel used to destroy the top layers of skin and cannot be performed at a medical spa or from a kit sold for home use.

Depending on your diagnosis, a combination of treatments may be recommended.
