Vitamin A can relieve some dry skin. The key to tender, full and shiny skin lies in the moisture content in the skin. For example, why the baby's skin is so delicate, shiny and elastic is because of its high water content. As the saying goes, her skin is tender and tender. Why old people's skin is dry, rough, shriveled, peeling and dull is because the skin has less water content. In cold, windy and dry seasons, it is a moisturizer for external use. In the most important season of skin conditioning, there are several ways to moisturize the skin: 1. The oiling method to prevent the evaporation of skin moisture is to apply vaseline to the skin, which can seal the skin and prevent the evaporation of water in the skin. This principle is used in Ponzi Vaseline skin cream market, but its disadvantage is that it is too greasy and easy to get dirty. 2. Moisture absorption and moisturizing method They use glycerol, sorbitol, propylene glycol and polyethylene glycol to absorb external moisture. They are water-absorbent and suck moisture from the atmosphere into the skin. For example, glycerin is water-absorbent and has a moisturizing effect, but it can't be pure. On the contrary, pure glycerin will absorb moisture in the skin. To make the ratio of 1: 3, add 10%~ 15% glycerol to the total prescription, which is oily and absorbent. 3. Hydration and moisturizing combined with hydration is a hydrophilic and water-soluble substance. It will form a network structure and turn the free water in the network into bound water. They are collagen, at least elastic, hyaluronic acid and so on. 4, repair keratinocytes, repair and moisturize, improve the protective function of the skin and achieve the purpose of moisturizing. Such as vitamins A, C, E, B5, fruit acid, etc. Can improve the function and metabolism of keratinocytes, thereby improving the moisturizing function of the skin. The simplest and most effective way is to drink more water, wash your face and sprinkle some water on your face often. Suggestions can be made from the following aspects: when taking a bath, choose a mild shower gel with weak acidity and avoid using alkaline soap with strong cleaning power, because even a neutral shower gel is alkaline relative to human skin. You should also avoid taking a bath with too hot water, and it is best to use a water temperature close to the body temperature (no more than 40 degrees). Bian Xiao recommended: Keep 25-year-old skin moist, dry, clean and fresh in autumn [skin care] Skin cleaning and maintenance [skin care] Four-month skin care plan and appropriately shorten the bathing time to avoid excessive loss of water and fat caused by heat. Don't rub hard when taking a bath, because overheated water and rubbing hard will wash away the protective layers such as sebum and keratin of the skin, which will easily hurt the skin and even cause local inflammation of the skin, making the nerves more excited and aggravating itching. Ten minutes after taking a bath, the moisture on the skin surface is basically dry, and then applying moisturizing body lotion, especially on the particularly dry parts such as limbs, can help the skin restore the balance of water and oil, form a thin film on the skin, and prevent water evaporation. Moreover, because the pores are slightly open just after taking a shower, skin care products are easier to absorb and penetrate. You should put on clothes and socks as soon as possible after applying skin care milk, which not only keeps warm, but also prevents the loss of skin moisture and sebum, and helps to strengthen the improvement effect on dry skin. After the skin is effectively moisturized, it can effectively reduce dryness and itching. Bian Xiao recommended: [Skin care] Fresh fruit maintenance [Skin care] Nine strategies of fruit cleansing, moisturizing, ginkgo milk, chrysanthemum pear soup cleansing and freckle removal, and clever use of milk: If you feel dry skin at ordinary times, you should also use lotion at any time to moisturize dry skin in time, with emphasis on calves and arms. The front part of the calf is the part with the least sebaceous glands in the whole body, so it is the most prone to itching and dandruff, and the arm is often exposed to the air, which is also the most prone to drying. Reduce the use frequency of exfoliating products and avoid the damage of excessive exfoliation to skin protective film. Skin care products should also be adjusted and updated in time with the changes of seasons. If your skin care products will tingle or even be red and itchy after use, it should be replaced immediately. Skin care lotion/cream with low irritation and high moisturizing degree should be selected to enhance moisturizing function. It is suggested that moisturizing cream or cream containing hyaluronic acid, collagen and other moisturizing ingredients can be used to lock water and moisturize. Pay attention to sun protection during the day. Although the sunshine in autumn is not as strong as that in summer, the power of ultraviolet rays in autumn is still not to be underestimated. Because the concentration of atmospheric ionic layer in autumn is thinner than that in summer, and the absorbed ultraviolet ray is less than that in summer, the ultraviolet ray is still quite strong. It can be said that the skin is more vulnerable to ultraviolet rays during this period, and ultraviolet rays are also one of the culprits of dry skin. So after applying moisturizing lotion during the day, don't forget to use sunscreen to protect your skin from various diseases. Bian Xiao recommended: break 1 egg, add appropriate amount of milk, and paste it, and apply 15 minutes every day. As long as it is applied for 3 months, your skin will be tender and fair.

In order to avoid evaporation of skin moisture caused by dry indoor air, indoor humidity should be increased as much as possible. Usually, it is appropriate to keep the humidity at about 50 degrees. If you stay in an air-conditioned room for a long time, it is recommended to use air humidifiers and other equipment indoors; Or you can take an economical way, such as putting a few fish tanks and hydroponics plants, which is also a good choice, which can increase indoor humidity and help keep skin moist. Before going to bed every night, you can also put a small basin of water on the bed, which can also play a certain role in humidification. Loose cotton should be used for close-fitting clothes, and it is best to absorb sweat and breathe freely to avoid skin itching caused by contact friction or hot sweat. At the same time, we should also avoid wearing sweaters, nylon and chemical fiber clothes to avoid irritating the skin and causing allergies. Be careful that some thermal underwear is made of composite sandwich material, that is, a fluffy chemical fiber is sandwiched between two layers of ordinary cotton cloth to keep warm. This chemical fiber component is easy to generate static electricity when worn on the human body, and will generate a large number of cations around the human body, which will stimulate the skin, reduce the moisture of the human skin, increase dandruff, and also cause skin itching. Therefore, people with allergic skin should try to wear underwear that is not easy to generate static electricity, such as pure cotton and silk.
