What is Actinic Keratosis?
Actinic keratosis (AK) is a common skin condition that is characterized by rough, scaly patches on the skin and is also known as solar keratosis. It is caused by sun damage and is often found on areas of the body that have been exposed to the sun, such as the face, scalp, arms, and hands. These patches tend to grow slowly and don’t typically appear in people under 40.
What are the symptoms of Actinic Keratosis?
The most common symptom of actinic keratosis is the appearance of rough, scaly patches on the skin. These patches may be pink, brown or red and can vary in size from a few millimeters to several centimeters. They may also be itchy or tender to the touch. Additional symptoms include itching, burning, bleeding or crusting, and in some cases a hard, wart-like surface.
How do you treat Actinic Keratosis?
The treatment for Actinic keratosis will depend on the severity of the condition. In mild cases, topical creams or ointments may be prescribed to reduce inflammation and encourage the growth of healthy skin. In more severe cases, cryotherapy, a procedure in which the affected area is frozen with liquid nitrogen, may be necessary to remove the damaged skin. In some cases, surgical excision or laser therapy may also be necessary.
In some cases, Actinic Keratosis can progress to become squamous cell carcinoma, a type of skin cancer. While not all AKs will progress to cancer, it is important to monitor any changes in the affected area and consult with a dermatologist if you notice any changes, such as growth or changes in color. Other risk factors for AK include fair skin, a history of sunburns, and a weakened immune system.
What causes Actinic Keratosis?
Actinic keratosis is caused by sun damage, specifically prolonged exposure to UV radiation. This damage can lead to the development of abnormal cells on the surface of the skin, which can form the rough, scaly patches characteristic of AK.
How do you prevent Actinic Keratosis?
Preventing Actinic keratosis can be done by taking steps to protect the skin from sun damage. This includes:
- Wearing protective clothing, such as long-sleeved shirts and hats
- Using a broad-spectrum, water-resistant sunscreen with an SPF of at least 30
- Avoiding tanning beds
- Seeking shade during peak sun hours (10am – 2pm)
Regular skin exams with a dermatologist can also help detect AK and other skin conditions early on. Schedule yours today by calling 515.875.9766.
