Actinic Keratosis
What is Actinic Keratosis?
Actinic keratosis (AKs) is a rough, scaly patch on the skin. It is caused by years of ultraviolet (UV) radiation exposure from the sun and tanning beds. AKs usually appear as red, pink, or flesh-toned patches that are scaly and feel rough, like sandpaper, when touched.
This condition is treatable. However, if an AK is left untreated, there is a chance of these spots developing into squamous cell carcinoma, a type of skin cancer. Early detection and treatment are key to preventing further complications.
Where does it appear?
AKs typically appear on areas of the skin that are most exposed to the sun.
These areas include the:
- Face
- Lips
- Ears
- Forearms
- Scalp
- Neck
- Back of hands
Treating Actinic Keratosis
Treating actinic keratosis helps eliminate your risk of developing skin cancer. Treatment options will depend on several factors, including the number and location of lesions, as well as your overall health.
At Oak Dermatology, our providers will use a demascope (a magnifying lens) to examine the lesions and recommend a personalized treatment plan.
Common treatment options include:
- Freezing AKs with liquid nitrogen to destroy abnormal cells.
- Applying topical medications. Prescription creams like imiquimod or 5-FU are applied directly to the AKs to eliminate them or trigger the immune system to attack them.
- Photodynamic Therapy (PDT): Applying a light-sensitive medication to the AKs, followed by exposure to a specific light to destroy targeted cells.
