3 types of allergies in the sun

The term “solar allergy” brings together three different events: lucite, solar hives and photosensitization.

It reaches the areas exposed to the sun such as neckline, arms, shoulders, top of the feet, legs, etc. in the form of small red pimples that itch. “”The polymorphic lucite is also triggered several hours after exposure in the form of vesicles which appear on the exposed areas. It can also appear with small sunnyness“Reports Dr. Michael Naouri, dermatologist.

► Solar hives occurs just after the start of the exhibition. It affects women more often between 20 and 40 years old. It manifests itself in hives and high itching. The person sometimes feels a feeling of tingling and/or burns before the appearance of symptoms. Other symptoms can then appear as headache, a feeling of discomfort. The heart rate can rise and hypotension is possible.

► There chemical photosensitization is the result of the meeting between the sun’s rays and a chemical as a medication. Medicines can cause abnormal skin reactions when exposure of all or part of the body to UV radiation. These drugs are said to be photosensitizing when they change the skin of colors or appearance.
