Actinic Keratosis
Understanding Actinic Keratosis
Actinic keratosis (AK) is a rough, scaly patch on the skin caused by years of accumulated ultraviolet (UV) radiation exposure from the sun or tanning beds. These precancerous lesions typically appear on sun-exposed areas like the face, lips, ears, forearms, scalp, neck, or back of the hands. AKs usually present as red, pink, or flesh-toned scaly patches that feel rough or sandpaper-like when touched. While AKs are treatable, it's important to note that a small percentage of these lesions may develop into squamous cell carcinoma, a type of skin cancer, if left untreated. Therefore, early detection and treatment are crucial to prevent such complications.
Treating Actinic Keratosis
Treating AKs eliminates lesions and reduces skin cancer risk. Treatment depends on the number, location, and your health. Your doctor will use dermoscopy to examine the lesions and recommend the best course of action. Some common treatment options include:
- Cryotherapy: Freezing AKs with liquid nitrogen to destroy abnormal cells.
- Topical Medications: Prescription creams like imiquimod or 5-FU applied directly to the AKs to eliminate 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.

FAQs
While AKs can appear as red or pink scaly patches, they are often felt more easily than seen, with a rough, sandpaper-like texture.
A dermatologist will typically diagnose AK through a visual examination and may use dermoscopy for a closer look.
At-home remedies are not recommended for AK treatment. Consulting a dermatologist is crucial for proper diagnosis and treatment.
Sun protection is key! Regularly applying sunscreen with SPF 30 or higher and minimizing UV exposure can significantly reduce your risk of AK.
