At present, it is the season of Grain Rain, with significant temperature fluctuations, a large increase in pollen and willow catkins, enhanced UV intensity, and a high incidence of skin allergies. The Ningxia Health Commission held a press conference on "Seasonal Seasons and Health" on the 21st, inviting relevant experts to answer questions on skin allergies. How to determine skin allergies and what are the specific symptoms of skin allergies? According to He Chenxia, chief physician of the Dermatology Department at Ningxia Hospital of Traditional Chinese and Western Medicine, if discomfort such as itching, redness, swelling occurs in a short period of time after exposure to pollen, prolonged exposure to sunlight, or changing skincare products, after ruling out skin dryness, itching, and mosquito bites, it can be basically judged as skin allergy. The specific manifestations of skin allergies can be summarized as' four itching, two redness, and one swelling '. ”According to He Chenxia, the "four itches" refer to skin itching, a crawling ant like sensation, intermittent severe itching, and the more you scratch, the more itchy it becomes; Two redness "refers to the appearance of patchy erythema on the skin, or diffuse redness of the entire skin with a noticeable burning sensation when touched; 'One swelling' refers to sudden swelling of the eyelids, lips, or cheeks, with shiny skin. According to He Chenxia, after experiencing skin allergies, the first step is to immediately stop all behaviors that may irritate the skin, stop using all skincare products, cosmetics, and even facial cleansers for the time being; The second step is home relief, which is only suitable for mild allergic situations; If the symptoms do not improve or even worsen after self care at home for 3 days, it is necessary to seek medical attention in a timely manner. He Chenxia mentioned in particular that there are some common skin care mistakes on the Internet, such as "more facial mask are the most moisturizing", "the more skin care products piled up, the more effective", "frequent face washing and exfoliation", etc. He Chenxia said that daily application of facial mask would make the skin excessively hydrated and destroy the protective barrier; The skin has limited absorption capacity, and applying skincare products indiscriminately can easily cause allergies and acne; The oil layer on the face is a natural protective layer. If washed too frequently or exfoliated too frequently, the face may become dry, red, and bloodshot. He Chenxia suggested that drinking more water is the basis of skin care. The indoor humidity should be kept at 40% -60%, which is better than applying facial mask; In terms of diet, one should eat less spicy and hot food, and drink less alcohol. I hope everyone can take care of their skin scientifically and spend spring comfortably
