Sunburned skin allergies are actually caused by the strong ultraviolet rays contained in sunlight. When ultraviolet rays shine on the skin, they can cause allergies and other damage to the skin. If sunburn-induced skin allergies occur, it is essential to avoid further exposure to sunlight and keep away from it. Secondly, keep the skin clean and avoid using irritating cleansing products. Finally, it is recommended to use cold compresses for treatment and apply some aloe vera gel to the affected areas of the skin.
