1. Shorten the time of bathing. Use lukewarm water, not hot water for bathing, and use mild cleansers. Gently pat the skin dry. 2. Use emollients after bathing. Ointments and creams are better than lotions. 3. Read the ingredients contained in skin care products. Deodorant soaps, toners containing alcohol, and products containing fragrances tend to irritate the skin and cause dryness and sensitivity. 4.You can use a humidifier when the air is dry. 5, wear cotton breathable clothes, such as 100% stored cotton clothes. If you want to wear wool or other rough fiber clothes, underwear need to wear cotton. 6, do not skip washing your hands. Hand washing can remove harmful bacteria and viruses. If you wash your hands a lot, you can use hand sanitizer instead. 7, after each time you wash your hands, use hand cream. If your hands are particularly dry, you can apply petroleum jelly externally before going to bed. If your hands are often immersed in water, you need to wear waterproof gloves.
