Actinic lichen planus is a type of lichen planus that is caused by long-term exposure to ultraviolet (UV) radiation from the sun. It is characterized by flat-topped, scaly, and itchy patches on the skin that are usually found on sun-exposed areas such as the face, neck, arms, and hands. Treatment typically involves avoiding further sun exposure and using topical corticosteroids or other medications to reduce inflammation.

The most common symptoms of actinic lichen planus include:

-Raised, scaly, or crusty patches on the skin
-Itching or Burning sensation
-Discoloration of the skin
-Thickening of the skin
-Painful or tender areas
-Blisters or ulcers on the skin
-Hair loss in the affected area

Actinic lichen planus is an inflammatory skin condition that is caused by long-term exposure to ultraviolet (UV) radiation from the sun. It is believed that UV radiation damages the skin, leading to an immune response that causes the rash. Other possible causes of actinic lichen planus include certain medications, such as antibiotics, and certain medical conditions, such as diabetes.

1. Topical corticosteroids: These are the most commonly prescribed treatment for actinic lichen planus. They can be applied directly to the affected area to reduce inflammation and itching.

2. Phototherapy: This involves exposing the affected area to ultraviolet light. This can help reduce inflammation and itching.

3. Oral medications: Oral medications such as antihistamines, antibiotics, and antifungal medications may be prescribed to reduce inflammation and itching.

4. Laser therapy: This involves using a laser to destroy the affected skin cells. This can help reduce inflammation and itching.

5. Cryotherapy: This involves freezing the affected area with liquid nitrogen. This can help reduce inflammation and itching.

Actinic lichen planus is a chronic skin condition that is not curable. Treatment typically involves topical corticosteroids, topical calcineurin inhibitors, and phototherapy. Oral medications such as retinoids, immunosuppressants, and antibiotics may also be prescribed.
