Break the “curse of changing seasons” and teach you scientific skin care

  Spring is sunny and the grass grows and warblers fly. It is a good time to go out to enjoy flowers and outings. However, due to pollen, catkins and dust flying freely in the air, many people who are prone to allergies are unfortunately “suffered” when they go out to play. Erythema, pimples, itching, peeling, etc. appear on the skin. Peng Xiliang, chief physician of the Dermatology Department of Zhengzhou Central Hospital Affiliated to Zhengzhou University, said that for the “sensitivity” crowd, skin care should be done in spring to break the “curse of changing seasons”.
  Skin Allergies≠Skin Sensitivity
  Ms. Xu ‘s face is often red, itchy, prone to rashes, and sometimes dry and peeling, which makes her very distressed when she loves beauty. I have seen many doctors, some said that it was skin allergy caused by contact with allergens, and some doctors said that Ms. Xu was caused by skin sensitivity.
  Peng Xiliang said that many people tend to confuse the two concepts of skin sensitivity and skin allergy, so as to blindly use drugs and increase the burden on the skin. In fact, skin allergies are congenital, while skin sensitivity is “acquired”. Skin allergy is an abnormal reaction of the human body to allergens. When allergic people are exposed to allergens, erythema, papules, edema, itching or tingling, and some respiratory diseases (such as asthma) will appear on the exposed parts of the face and neck. , rhinitis, etc.). The skin sensitivity is due to excessive cleaning, improper selection of cosmetics, emotional anxiety, lack of sleep and other reasons, making the skin intolerant to external stimuli and in a sensitive state.
  According to Peng Xiliang, to identify sensitive skin, you can use capsaicin, lactic acid or low-concentration alcohol to smear it on the skin for 3 to 5 minutes. If redness, swelling and knife-like pain appear, it means sensitive skin.
  Skin allergy and skin sensitivity are very different in treatment. Skin allergy is mostly transient. It can be treated by taking antihistamines orally and applying anti-allergic ointment. At the same time, keep away from allergens, and the allergic symptoms will gradually disappear. The treatment of sensitive skin is more difficult and the treatment cycle is longer.
  Peng Xiliang suggested that if the skin is sensitive, you should immediately stop using various skin care and makeup products, wash your face with water below body temperature, apply cold compresses to the skin with ice packs and cold towels, and use medicines rationally under the guidance of dermatologists. After the “sensitivity alert” is lifted, learn to “subtract” skin care products. It is recommended to choose external medical skin care products, which can repair the damaged skin barrier and keep the skin away from sensitizing and harmful ingredients.
  ”Moisturizing” the skin is just a publicity gimmick.
  I don’t know when it started, the advertisements of skin care products are all under the banner of “hydrating”. Therefore, many people work hard on skin care, sprays, lotions, and masks do not fall off, but their skin is still dry and rough. , Peeling, acne.
  In Peng Xiliang’s view, “hydrating” the skin is just a publicity gimmick. In fact, it is difficult for the skin to absorb moisture directly from the outside world.
  Although the desire for “hydration” fell through, the concept of “moisturizing” is indeed correct. Peng Xiliang suggested that if you want to keep your skin moisturized, you should learn to use face creams reasonably. Because the cream is a water-in-oil structure, the oil content is greater than water, and it is thicker, so the ingredients that moisturize the skin are not easily evaporated, and the moisture content of the skin is maintained, and the moisturizing effect is better.
  There are still many people who are keen on exfoliating their skin. Peng Xiliang said that the stratum corneum is a dense layer of apoptotic cells, which is an important protective layer of the skin. The oil film outside the stratum corneum is a protective film that can moisturize and shield the skin from external stimuli. Frequent exfoliation can seriously damage this line of defense, weakening the skin’s resistance to external agents such as bacteria.
