First of all, there is no such disease as sun poisoning in clinical practice. If a patient has red, itchy skin with papules and herpes after sun exposure, then he or she should be considered to have sun dermatitis. The patient can take oral antihistamines, such as loratadine, cetirizine, paracetamol, and glucocorticoids, as well as glyburide lotion for external application, and must pay attention to the prevention of sun exposure. If the patient is referred to as a sunburn, the skin appears like red, even red, swollen, peeling, flaking, blistering, this situation should be referred to sunburn. In this case, if the patient’s local is not very serious, only erythema appears, then you can apply a cold compress like saline to freeze later, at the same time, you can take some antihistamines orally, and apply glycopyrrolate lotion and glucocorticoid to apply topically. However, if the blisters are obviously broken, boric acid solution can be applied as a wet compress.
