Yesterday, this edition published a report on how to choose sunscreen for summer sun protection. Many readers inquired about how to deal with skin redness and pain after exposure to sunlight. Li Jing, Director of the Medical Aesthetics Department of the Affiliated Hospital of the Municipal Institute of Traditional Chinese Medicine, reminds that if the skin is sunburned after exposure to sunlight, it can be repaired through four steps to accelerate the repair of the skin barrier. Step 1: After 4 to 6 hours of exposure to the sun, the skin will experience redness, swelling, and tingling sensation, mainly through local cooling, analgesia, and anti-inflammatory measures. It is recommended to immediately go to a cool or indoor environment for cooling treatment. At home, ice milk or ice physiological saline can be used, soaked with gauze or towels, and then applied externally to sunburned skin areas. Apply externally for 5 to 10 minutes each time and repeat the operation. Because the fat, protein, and other components in milk help repair the skin barrier, and ice compress can cause the contraction of skin capillaries to have analgesic and anti-inflammatory effects. Green tea can also be used, and the tea polyphenols contained in green tea can also resist UV damage. Step 2: When the skin feels dry and tight, the main treatment measure is to replenish water and moisturize. The simpler the ingredients of moisturizing products, the better. Try not to use some products containing alcohol, essence or stimulating ingredients to avoid allergic reactions. While strengthening external hydration and moisturizing of the skin, it is also important to drink more water to increase the replenishment of water in the body. Step 3: During the scabbing and peeling period, it is important to pay attention to natural peeling and avoid secondary damage caused by skin tearing. Strengthen the use of lotion or cream, soften the scab and accelerate the repair of skin. Step 4: During the pigmentation phase, which is the anti melanosis phase, the main treatment principle is to whiten and moisturize. Drugs and cosmetics containing whitening ingredients such as vitamin C, vitamin E, hydroquinone, arbutin, and tranexamic acid can be used externally to accelerate the metabolic regression of pigmentation.
