What is a sun allergy?
Some skin types exhibit an extreme reaction when exposed to the sun and UV rays. We call this reaction a sun allergy. A sun allergy is an immune system reaction that is triggered by exposure to the sun. It is characterized by redness, swelling, itching, bumps, blotches, and sun blisters. The interesting thing about sun allergies is that the allergic reaction only materializes on those areas that were exposed to sunlight.
Symptoms usually occur after excessive sun exposure. A true sun allergy is relatively rare and primarily affects fair-skinned women between the ages of 20 and 40, but anyone can have an occasional allergic reaction after spending too much time in the sun.
Itchy skin and blisters – could this be a sun allergy?
People often display symptoms similar to those of a sun allergy, but that does not mean that what they are experiencing is actually a sun allergy. The allergic reaction could be triggered by a person’s sunscreen ingredients or by the combined effect of perfume and sunlight. These kinds of reactions are often referred to as chemical photosensitivity or exogenous photodermatoses. The symptoms arise when sunlight interacts with a chemical substance that has either been ingested or applied to the skin, such as antibiotics, perfumes, or creams. Primary photodermatoses, on the other hand, is an allergic reaction that is caused by sunlight alone.
How can a sun allergy be avoided?
The most obvious solution is, of course, to stay out of the sun. However, many sun allergies are caused by products that are applied to the skin. This is why we recommend purchasing alternative skin care products if you suffer from a sun allergy. Do not apply perfume when going out in the sun and check the ingredients in your sunscreens, creams, and make up. Many of these products contain fragrances that can cause itching, red blotches, age spots, and bumps when exposed to the sun. Take care of your skin by being very careful about the skin-care products you use.
