Photosensitive

Photosensitivity refers to an abnormal reaction to sunlight and other sources of light. It is a condition where an individual's skin reacts abnormally when exposed to light. This can be caused by various substances or conditions that make a person's skin more sensitive to light.

Causes

Photosensitivity can be caused by various factors. Some of these include:

• Certain medications such as antibiotics, antihistamines, and chemotherapy drugs
• Certain diseases or conditions such as lupus, porphyria, and xeroderma pigmentosum
• Certain chemicals found in cosmetics and personal care products
• Certain plants and vegetables such as limes, celery, and parsley

Symptoms

The symptoms of photosensitivity can vary depending on the cause. Some common symptoms include:

• Redness and inflammation of the skin
• Itching or burning sensation
• Blisters or hives
• Dark patches on the skin
• Increased risk of skin cancer

Diagnosis

Photosensitivity is usually diagnosed based on the patient's symptoms and medical history. The doctor may also perform a physical examination and order tests such as a skin biopsy or blood tests to rule out other conditions.

Treatment

The treatment for photosensitivity depends on the cause. It may include avoiding exposure to sunlight, using sunscreens, wearing protective clothing, and taking medications to reduce inflammation and itching. In some cases, the underlying condition causing photosensitivity may need to be treated.
