”Doctor, look at my face, it’s red and itchy at this time of year, what’s wrong with it?” Ms. Wu asked the doctor anxiously at the dermatology outpatient clinic of Wuhan First Hospital. Every year when spring is in full bloom, there are dozens of patients with facial skin allergies in the dermatology department of Wuhan First Hospital every day, and many of them report to the dermatology department year after year, and many of them have become friends with the dermatologists. Facial skin allergies often occur in young and middle-aged women, ranging from small red papules and itchy skin to diffuse erythema, skin edema, and even oozing and ulceration in severe cases. The face is one of the most concerned parts of our body. If red spots appear on the face, many people will feel very uncomfortable and even reluctant to go out. Why are facial allergies prone to occur this season? Experts from the Department of Dermatology of the First City Hospital introduce that the spring is bright, the sun’s ultraviolet rays are enhanced, the body’s metabolic capacity gradually increases, the sebaceous glands secrete more, and the skin is very sensitive at this time, coupled with pollen, willow and dust scattering, and many women abuse cosmetics, it is easy to make skin allergies. Experts point out that many patients often wash their faces with too hot water, or use skin cleansers such as soap and cleanser too often, and these physical and chemical stimuli can damage the skin’s barrier and vascular regulation function. The skin is allergic to ultraviolet rays, and the nature of the face is prone to change after sun exposure, which can easily make the skin allergic; many women blindly pursue novel and expensive cosmetics, which contain a variety of antigenic substances (such as fragrances, preservatives, pigments, etc.), which produce allergic reactions that are not easily noticed, and often symptoms appear only after a period of use. The appearance of dermatitis symptoms after the random use of drugs applied externally, especially topical glucocorticoid treatment, is also prone to produce irritation and rash rebound. What to do after facial allergy? 1. Do not scratch: the skin will be continuously stimulated and thickened due to scratching. Avoid using alkaline soap: Alkaline soap can be a chemical irritant to the skin and can aggravate atopic dermatitis, so be sure not to wash your face with alkaline soap. Do not use hot water: facial atopic dermatitis when the skin will occur in varying degrees of redness, papules, blisters and other conditions. If the patient uses hot water, it will make the redness and swelling worse. 4. Be careful with cosmetics: before using new cosmetics externally, do patch test, if there is no adverse reaction, then use; do not change cosmetics frequently; 5. Reduce ultraviolet radiation: when outdoor activities, start with a small dose of ultraviolet radiation, gradually increase the amount of light, so that the skin tolerance; try to avoid prolonged exposure to the sun, avoid going out at 10:00 to 14:00; travel to do a good job of sun protection; 6. Reasonable diet: prohibit the consumption of spicy and irritating foods such as: chili, wine, strong tea, coffee, etc., which will make facial atopic dermatitis aggravated. 7. Do not blindly use medication: the appearance of facial dermatitis must be under the guidance of a doctor to use medication, do not abuse drugs on their own.
