Inflammatory skin reaction from UV-A rays: what helps with sun allergy

The sun allergy causes unpleasant skin problems in summer. Sufferers suffer from reddening of the skin, blisters or small itchy pimples after a stay in the sun. Health experts explain what can help against the symptoms.

Skin problems from sunlight

Soaking up sunlight ensures a good mood and is good for your health. Finally, the vitamin D store is recharged. But for some people, sunbathing quickly causes skin problems due to allergic reactions. Proper protection and special care are particularly important for those affected, health experts explain.

More and more people suffer from a sun allergy

According to health experts, the number of people who have allergic reactions to strong sunlight has increased in recent years. More and more children suffer from sun allergy.

This allergy, the so-called polymorphic light dermatosis, is noticeable by itchy pimples, blisters, wheals and reddening of the skin, which usually occur a few hours or even days after staying in the sun, DAK Gesundheit explains in a current press release.

For some people, the skin begins to tingle uncomfortably while sunbathing.

The skin irritation is most common on the neck, décolleté, upper arms and face.

The symptoms usually appear when the skin is exposed to an unusually high dose of light after a long period of time - for example in spring or during a "sun vacation" in winter.

The symptoms usually go away on their own after a few days if the body does not have to go into the sun again during this time.

Inflammatory skin reactions

According to the health insurance company, the long-wave UV-A rays contained in sunlight, which penetrate into the deeper layers of the skin, are to blame for a sun allergy.

They cause an inflammatory skin reaction in at least every tenth German citizen.

In addition, fragrances and preservatives in sun creams can react with the UV-A light and thus lead to further skin irritation, the so-called Mallorca acne.

Taking certain medications such as antibiotics, antihypertensives or psychotropic drugs also make the skin more sensitive to the sun.

What can help those affected?

If the characteristic symptoms of sun allergy occur, the skin should be cooled with a damp cloth.

In addition, the DAK points out that a gel with hydrocortisone (pharmacy) alleviates the symptoms quickly and effectively. Anti-allergy drugs (antihistamines) or calcium tablets (both from the pharmacy) also help.

Fresh aloe vera juice or an unscented gel with the ingredients of this plant also calm the skin.

In addition, the affected skin areas should be protected with suitable clothing and direct sunlight avoided.

How to prevent

Some preventive measures can help prevent the uncomfortable symptoms of a sun allergy. DAK Gesundheit recommends:

  • Only use sun creams or gels without fragrances and preservatives - ideally from the pharmacy.
  • Make sure you have a high sun protection factor (30 to 50).
  • Sun gels with special filters also protect against UV-A rays - ideally the package says "UV-A protection according to the Australian standard".
  • Always apply sun gel generously and always apply cream after bathing - even with waterproof products.
  • Switch to low-additive pharmacy products for day care during summer or on vacation.

The experts have a few more tips to help you enjoy your next vacation to the fullest:

Get used to the sun slowly: in the first few days of spring, a few minutes at a time are enough.

The midday sun should be avoided - at this time the sun's rays are strongest.

If sun-induced skin irritation does not go away after a few days, a doctor should be consulted. (ad)
