What are the symptoms of UV allergy in babies?

Children's skin is relatively delicate, so their body's resistance is very weak during this period. It is easy for them to have allergies in daily life. Ultraviolet allergy is relatively common. So what are the symptoms?

Ultraviolet allergy is also called "solar dermatitis", which usually manifests as itching in the areas exposed to the sun. The longer the exposure to the sun, the more severe the allergic reaction will be, and the skin itching will last for 24 to 48 hours, or even longer. People with allergies will experience redness, burning, heat and pain on the irradiated skin. At the same time, it will cause a sharp increase in free radicals in the body, causing wrinkles, pigmentation and cell damage on the local skin. In severe cases, it may change the immune system. Symptoms of ultraviolet allergy often manifest as erythema, papules, wheals or blister-like rashes on the face, neck, forearms, sides of the body, back of the hands and other easily exposed parts. The symptoms worsen after exposure.

Symptoms of first-degree ultraviolet allergy: diffuse erythema appears on local skin after sun exposure.

Symptoms of second-degree ultraviolet allergy: local skin redness and swelling, followed by blisters or even bullae, with tense blister walls and light yellow blister fluid. Subjective symptoms include burning or itching. After the blisters burst, they become erosive and soon dry and form scabs, leaving behind pigmentation. Very severe UV allergy may be accompanied by systemic symptoms such as fever, headache, palpitations, fatigue, nausea, and vomiting.
