Various reactions to sunlight exposure can cause Sun allergy (photosensitivity or photodermatitis). There are four main types: polymorphic light eruption (PMLE), solar urticaria, photoallergic reaction, and actinic prurigo.
The classification is the following:
The most common prescription medications that can cause photoallergic reactions are:
It's important to note that these risks can vary depending on the individual and their specific circumstances.
PLE: Exposure to intense or prolonged sunlight can result in itchy, red, and inflamed skin rashes.
Actinic Prurigo (AP): People with a genetic predisposition are at a higher risk of developing actinic prurigo.
Photoallergic Eruption: These allergic reactions can range from mild rashes to severe blistering, and they may take hours or even days to appear after sun exposure.
Solar urticaria: Exposure to sunlight can cause hives, itching, swelling, and even systemic symptoms such as difficulty breathing or low blood pressure in severe cases.
If you suspect you have a sun allergy, it is advisable to consult a healthcare professional for an accurate diagnosis and appropriate management strategies.
Photosensitivity (photodermatitis or sun allergy) can manifest in skin rashes, itching, redness, and swelling.
An immune system response to UV exposure or certain substances (medications, chemicals, etc.) can make the skin more sensitive to sunlight and trigger sun allergy rashes.
Several risk factors can increase your chances of developing a sun allergy.
An abnormal skin reaction to sunlight or other ultraviolet (UV) light sources provokes photodermatitis. The symptoms can vary depending on the individual and the specific type of photosensitivity.
The most common symptoms are:
In severe cases or certain types of photodermatitis, individuals may experience systemic symptoms such as headache, nausea, dizziness, fatigue, or fever.
Sun allergies can be challenging to diagnose because they can often be confused with other conditions, such as eczema or hives.
A healthcare professional will typically ask about your symptoms, sun exposure patterns, and medications or substances you have been using.
A photo test may help, where small areas of the skin are exposed to controlled amounts of UV light to observe the reaction.
A skin biopsy or patch testing may determine the specific cause of photodermatitis or rule out other underlying conditions.
