Summer, sun, sunshine – for most of us the most wonderful time of the year. But for some people, contact with the sun causes certain symptoms, such as redness, swelling or even blisters. In this article we will tell you what you can do to avoid such, sometimes painful, symptoms.
What lies behind a sun allergy
From a medical point of view, the term sun allergy does not even exist. It is more of a colloquial term that covers various reactions between the body and UV radiation. The body is unable to fully activate the protective mechanism against UV radiation. One of the most common forms is the so-called polymorphic light dermatosis (PLD). Young women with light skin in particular are often affected by this manifestation. It tends to occur on parts of the body that are often in contact with the sun, such as the neck, shoulders, arms and legs. The susceptibility is particularly high when the skin comes into increased contact with sunlight again after a long period of absence from the sun, such as in spring. After hours or a few days, redness, nodules or blisters may form on areas of skin that have been exposed to the sun, accompanied by severe itching. Another very common form is the so-called Mallorca acne. What may sound funny at first is, however, anything but fun for those affected. Despite adequate sun protection (or perhaps because of it), red, itchy spots often appear after the first intensive sunbathing on vacation. However, it is not acne in that sense; it is probably called that because the appearance is similar to conventional acne. It is believed that an interaction between UV radiation and the fatty components of sunscreen leads to such a reaction.
This is what you can do to prevent a sun allergy
The absolute be-all and end-all - generally applies to all skin types and even without allergies - is the right sun protection. Make sure your skin is protected with a high sun protection factor and reapply regularly. Particularly vulnerable areas of the body such as the neck, ears and generally the sensitive head region or feet should also be covered with clothing. The aggressive midday sun between 11 a.m. and 3 p.m. should also be avoided at best, as UV radiation is strongest during this period. In general, good advice is to gradually get used to the sun and not to expose yourself to the blazing sun for a long time from one day to the next. If you are prone to particularly severe reactions, it is best to contact your dermatologist, who can recommend various forms of therapy, among other things. If irritation does occur, cooling and certain medications can provide relief.
