1. Easy to scar
When there is urticaria on the face, it is necessary to pay special attention to sun protection. Otherwise, if the UV is too strong, it will directly radiate our skin. In order to avoid skin cells being oxidized, the human body will secrete a large number of melanin to protect, which will lead to pigment precipitation and scar formation.
2. May aggravate redness, pruritus and tingling
When patients with urticaria go out to the sun, it will increase the skin surface temperature, stimulate the histamine release of skin cells, and aggravate the red rash, swelling, itching and even tingling in the affected area.
3. May cause skin inflammation
If urticaria patients' skin is scratched and festering, if they continue to bask in the sun, the skin will be infected under the stimulation of ultraviolet rays, causing skin inflammation.

How to repair urticaria after exposure to the sun
1. Mineral spray + gel skin care
After skin sunburn, you can use mineral spring spray to replenish water for skin. However, it is necessary to spray after the skin cools down, because when the skin temperature is too high, spraying immediately will make it cool down, but because the temperature difference between hot expansion and cold contraction is too intense, the skin is prone to allergic symptoms, resulting in secondary injury.
After using the spray, immediately use the face paper, cotton pad or clean towel to dry up the water, otherwise it will take away more water from the skin due to excessive evaporation. After the skin is replenished with a lot of water, it can calm the skin immediately with non irritating products. The gel containing natural ingredients such as aloe and hamamelis is the most suitable for calming the skin after sun exposure.
2. Tea wash face
Dip the cotton ball in the tea and gently pat the red part of the quilt, so as to soothe the skin and reduce the burning sensation. If the area of sunburn is too large, you can also add strong tea to the washbasin to soak the sunburned skin in water for a few minutes, the effect will be more significant.

Smear the gelatinous substance in the small section of aloe vera on the hot skin, and keep it for one night after fixation, so that the aloe ingredients can fully penetrate. The next morning, you will find that the phenomenon of skin redness and fever will disappear.
