An Actinic Keratosis (AK) is a precancerous skin growth that forms as a result of significant damage caused by ultraviolet (UV) rays from the sun or indoor tanning. If left untreated, AKs have the potential to develop into squamous cell carcinoma, a type of skin cancer.

Actinic keratoses (AKs) can be treated before they develop into skin cancer. If skin cancer does occur, early detection through treatment often results in a cure.

What are Actinic Keratoses (AKs)?

AKs are rough, dry, scaly patches or growths that form on skin that has been exposed to significant sun over the years. They are common in areas that have seen prolonged sun exposure.

Signs & Symptoms:

  • A rough patch on the skin that may not be visible but can be felt.
  • A rough growth that feels painful or is sensitive to touch.
  • Itching or burning sensations.
  • On the lips, they appear as dry skin patches that do not improve with moisturizers or chapstick use.

Treatment Options for Actinic Keratoses (AKs)

  • Cryotherapy:
    Cryotherapy involves freezing the visible AKs with liquid nitrogen, causing the treated skin to blister and peel off within a few days to weeks. This is one of the most common treatments for AKs. After healing, a small white mark may remain on the skin.
  • Chemical Peel:
    A medical-grade chemical peel, stronger than those available at salons or for at-home use, is applied to destroy the top layers of skin. The treated area may become inflamed and sore, but healthy new skin will form as it heals.
  • Curettage:
    During curettage, your dermatologist carefully removes the visible AK with a curette (a specialized instrument). If needed, electrosurgery may be used afterward to burn away additional damaged tissue. New, healthier skin will gradually replace the treated area.
  • Photodynamic Therapy (PDT):
    In PDT, a solution is applied to the skin, making it more sensitive to light. After a few hours, the treated area is exposed to a visible light source (such as blue or laser light), which activates the solution and destroys the AKs. As the skin heals, new, healthy skin will appear.
  • Prescription Medications:
    Topical prescription medications can be used at home to treat AKs. These may be used alone or in combination with in-office treatments for enhanced effectiveness.
