Introduction
After a UV allergy reaction, the skin in areas exposed to sunlight will become swollen and red. The degree of swelling may vary depending on individual differences and the intensity of sun exposure; in severe cases, it may be accompanied by pain and a burning sensation. Along with the swelling, intense itching is commonly experienced. This itching may lead to continuous scratching by the patient, thereby worsening the skin damage.
Ultraviolet allergy, also known as solar dermatitis, is an abnormal photosensitive reaction caused by sunlight acting on the human body. Its symptoms typically appear on the skin after sun exposure, mainly including skin redness and swelling, itching, blisters, peeling, fatigue, and other manifestations. The analysis is as follows:
1. Skin Redness and Swelling
After a UV allergy reaction, the skin in sun-exposed areas may become red and swollen. The severity of redness and swelling may vary depending on individual differences and the intensity of sunlight exposure; severe cases may be accompanied by pain and a burning sensation.
2. Itching
Along with skin redness and swelling, there is often intense itching. This itching may cause patients to scratch continuously, further aggravating skin damage.
3. Blisters
In more severe cases of UV allergy, blisters may develop on the skin. Blisters typically appear on top of red, swollen skin and contain clear fluid, possibly accompanied by pain.
4. Peeling
As the allergic reaction progresses, the skin may begin to peel. Peeling usually occurs after the blisters subside, forming a thin layer of flaky skin.
5. Fatigue
UV allergy may cause patients to experience general fatigue. The feeling of fatigue may worsen due to bodily discomfort and increased energy consumption caused by the allergic reaction.
In daily life, it is advisable to avoid going outdoors during peak sunlight hours. If outdoor exposure is unavoidable, protective measures should be taken, such as applying sunscreen, wearing a wide-brimmed hat, and using an umbrella for shade.
