For winter facial allergies, the first thing to do is to pay attention to moisturizing. Because the winter season is cold and dry, it is easy to cause dryness of the skin. After the dryness of the skin, it may cause fine breakage of the skin surface and lead to the aggravation of allergy. Moisturizing can be treated by applying vitamin E ointment, dimethicone oil, and blue rinse cream. If it is accompanied by significant itching, it can be treated with topical application along with oral administration of levocetirizine hydrochloride capsule 1 time/day, 1 capsule/time, combined with compound glycopyrrolate capsule 3 times/day, 2 capsules/time. Avoid hot water for scalding during the treatment process, because too hot water may cause accelerated loss of facial moisture, and avoid spicy and irritating foods, including raw onion, raw garlic, chili, etc.
