Fotoallergien

Fotoallergien, also known as photoallergic dermatitis or photo contact dermatitis, is a type of skin reaction that occurs when the skin is exposed to certain substances, known as photosensitizers, and then exposed to sunlight or artificial light. This condition is more common in individuals with fair skin, light-colored eyes, and red hair. The most common triggers for fotoallergien include:

1. Plants: Certain plants, such as poison ivy, poison oak, and poison sumac, contain oils that can cause an allergic reaction when they come into contact with the skin and are then exposed to sunlight.

2. Medications: Some medications, including certain antibiotics, antimalarials, and nonsteroidal anti-inflammatory drugs (NSAIDs), can act as photosensitizers.

3. Cosmetics: Certain cosmetics, such as sunscreen, makeup, and hair dyes, may contain ingredients that can cause a photoallergic reaction.

4. Food: Some foods, like certain fruits and vegetables, can cause a photoallergic reaction in individuals who are sensitive to them.

Symptoms of fotoallergien typically appear within 12 to 72 hours after exposure to the photosensitizer and sunlight. They may include redness, itching, swelling, and blisters on the affected area. The symptoms usually resolve within a few days to a few weeks after avoiding the trigger and the affected area is no longer exposed to sunlight.

Treatment for fotoallergien focuses on avoiding the trigger and protecting the affected area from sunlight. This may involve using sunscreen, wearing protective clothing, and avoiding activities that expose the skin to sunlight. In some cases, topical corticosteroids or other medications may be prescribed to help manage symptoms. If you suspect you have fotoallergien, it is important to consult a healthcare professional for proper diagnosis and treatment.
