Skincare allergies should first be stopped immediately and the unabsorbed skincare products should be washed with warm water, while improving habits and diet to see if the allergy symptoms can be relieved. If it does not subside on its own, you should go to the dermatology department of a regular hospital in time to seek treatment under the guidance of a doctor: 1. Seek medical attention in time: Since skin allergy will show fever, redness, swelling, itching and flaking, topical hydrocortisone cream, dexamethasone acetate cream, etc., or oral levocetirizine hydrochloride tablets, loratadine tablets, etc., can effectively relieve the symptoms under the guidance of a doctor; 2. Reduce stimulation: During the allergy period, stop using all skin care products or cosmetics, clean your face with warm water every morning and evening, and use soft towels or tissues to wipe your face to reduce skin irritation. When going out, you need to bring a good mask, and at the same time you can hold a sunshade or wear a hat to reduce the stimulation of the skin by airborne particles and ultraviolet rays; 3, healthy life: during the period of skin allergy, patients should avoid staying up late, smoking, and ensure sufficient rest. Also stay away from spicy, stimulating and greasy diet, such as spicy hot pot, fried chicken, milk tea, alcohol, milk, strong tea, seafood, as well as beef and mutton. Drink more water and consume more fresh vegetables and fruits, such as spinach, pears, bananas, etc.
