Wear a neck gaiter and a hat to prevent sun allergy on your face and neck.

A few years ago, I developed a sun allergy, and when my skin is exposed to sunlight, I get hives and itching. So, to prevent sun allergy, I tried various methods and started wearing a neck gaiter and a wide-brimmed hat. It's a bit uncomfortable, but since I started wearing a neck gaiter and a wide-brimmed hat to prevent sun allergy, I can enjoy outdoor activities without worrying about hives. Sun allergy cannot be treated with oral medication, and there are no specific medicines to cure it. Therefore, the only way to prevent sun allergy is to avoid exposing the skin to sunlight as much as possible. When going outside or engaging in outdoor activities, the areas most exposed to sunlight are the face and neck. The rest of the body is covered with clothes, so it's okay, but the face and neck are exposed to sunlight, which causes hives to form on the ears and neck skin. Initially, I wore a baseball cap to prevent sun allergy. However, baseball caps do not cover the ears and neck, so hives kept appearing in those areas, and the prevention was ineffective. Therefore, I started wearing a wide-brimmed hiking hat during outdoor activities. This way, I didn't get hives on the ears and the skin below the ears, so I was able to prevent sun allergy to some extent.

But still, sometimes I get hives on my neck. I think it's because, depending on the angle of the sunlight, even a wide-brimmed hiking hat doesn't completely block it. So, I wear a thin neck gaiter. Covering my neck completely from the sunlight helps prevent sun allergy.

So, although it's inconvenient, I always wear a wide-brimmed hiking hat and a neck gaiter to prevent sun allergy. This is the only way to prevent sun allergy.
