Actinic dermatitis

Actinic Dermatitis is a skin condition that results from exposure to ultraviolet (UV) radiation. It is also known as photosensitivity, solar dermatitis, or photoallergic dermatitis.

Causes

Actinic dermatitis is primarily caused by prolonged exposure to the sun's harmful ultraviolet (UV) rays. However, it can also be triggered by exposure to artificial sources of UV light, such as tanning beds or phototherapy lamps. Certain medications, such as tetracycline antibiotics or thiazide diuretics, can also increase the skin's sensitivity to UV light and contribute to the development of actinic dermatitis.

Symptoms

The symptoms of actinic dermatitis can vary, but they typically include redness, swelling, and a burning sensation on the skin. In severe cases, blisters may form. The skin may also become thickened and scaly over time. These symptoms are usually confined to areas of the skin that are exposed to the sun, such as the face, neck, and hands.

Diagnosis

Actinic dermatitis is usually diagnosed based on the patient's symptoms and medical history. A dermatologist may also perform a physical examination of the skin. In some cases, a skin biopsy may be necessary to confirm the diagnosis and rule out other skin conditions.

Treatment

The primary treatment for actinic dermatitis is to avoid exposure to UV light. This can be achieved by wearing protective clothing, using sunscreen, and avoiding outdoor activities during peak sunlight hours. Topical corticosteroids may also be prescribed to reduce inflammation and relieve symptoms. In severe cases, systemic medications such as prednisone may be necessary.

Prevention

Prevention of actinic dermatitis involves minimizing exposure to UV light. This includes wearing protective clothing, using a broad-spectrum sunscreen with a high sun protection factor (SPF), and avoiding the sun during peak hours. Regular skin checks are also important for early detection and treatment.
