Sun allergy in children can be triggered by the harmful effects of the sun's rays. Solar radiation can alter the well-being of your skin. However, due to the fact that not all the reactions that appear on the skin of children after exposure to the sun are allergic, it is essential to take extreme precautions since most are due to the action of the sun on the skin. skin due to overexposure, sunbathing at unsuitable hours or not using photoprotective creams, which can lead to burns or erythema.

Among allergic reactions to the sun, two types must be distinguished: one is the solar urticaria, which is triggered directly by the sun, and another is allergy to the sun orphotoallergic reaction, which is caused by other substances when they come into contact with sunlight.

A true allergy to the sun is a disorder of the child's immune system, which is responsible for the appearance of the lesions, after minimal exposure to sunlight. This allergy is also known as solar urticaria and affects 2 percent of children that are exposed to the sun. Sun allergy causes intense itching on the skin and manifests itself as a welt or eczema.

The allergy does not get worse in successive exposures, but it recurs regularly, as long as the child is exposed to the sun with the same intensity. In the most severe cases, it can cause dizziness, choking, or headaches. Sun allergy is not hereditary, nor is there any collective group with a greater tendency to develop it.

There is another type of allergy to the sun, produced by phototoxicity, when a substance that is applied to the skin or ingested, becomes toxic to the skin when exposed to the sun. It is known as a photoallergic reaction or photosensitization and manifests itself as a red rash on the skin. Sun allergy is the result of the interaction of three factors: radiation, the skin, and the photosensitizer.

And is that some topical substances such as certain medications (antibiotics, anti-inflammatory, antihypertensive, diuretic, antiepileptic, chemotherapeutic or anti-acne), sun creams, perfumes, deodorants, cosmetics, industrial, horticultural or livestock products, plants or other products can increase the sensitivity that have some children and people in the sun, and cause these photoallergic reactions more and more frequent among the population when the summer arrives.

Sun allergies are diagnosed by exposing the child to the sun or to an ultraviolet ray lamp with the appropriate wavelength, while photosensitization is diagnosed by means of the so-called "photo-patch", which consists of applying the sensitizing drug or substance to small patches placed on the skin, making the sunlight or ultraviolet rays shine on that area.

Treatment, in cases of photosensitization, consists of eliminating the photosensitizing substance to end the problem. However, for solar urticaria, sun exposure should be avoided. In some cases, desensitization of the skin has been achieved by subjecting the child to brief exposures during the winter with a sunlamp.
