Sunburn is generally known medically as solar dermatitis. The best way to repair it usually does not exist, but it can be improved by general treatment and medication. 1. General treatment: For patients with solar dermatitis, their sunburned areas need to be protected from sunlight again to avoid secondary damage. In addition, you can also apply moisturizing products, such as vitamin E milk, which can moisturize the skin and relieve discomfort. At the same time, you need to drink more water to avoid water loss. 2. Medication: It is recommended that patients follow the doctor’s instructions to use recombinant human basic fibroblast growth factor gel, which can help relieve local symptoms and promote recovery. You can also use hydrocortisone ointment, which has anti-inflammatory effect and helps the skin lesions to recover. Sunlight dermatitis is not the only way to repair, it is recommended that patients go to a regular hospital, with the doctor for standardized treatment.
