Dry skin. Dry skin will appear in autumn and winter. Pay attention to moisturizing. Now there are several ways for you to choose which one to try and which one is more affordable. There is a reason for dry skin. With the increase of age, the skin's water retention capacity will decrease, and sebum secretion will also decrease, thus accelerating the evaporation of skin moisture. Second, the skin surface with insufficient sebum secretion is formed by sebum membrane, which can help the skin maintain proper moisture. Once the secretion of sebum is reduced, it can not meet the needs of making sebum film, and the skin will become dry. Third, the temperature drops. In the cold winter, the secretion of sebum and sweat will decrease rapidly, but because the air is too dry, the moisture of the skin will gradually evaporate, the skin surface will become rough and the resistance will be weakened. Fourth, lack of sleep, fatigue, lack of sleep and fatigue will cause considerable harm to the body and the blood circulation will deteriorate. If the health is out of balance, the skin will be lifeless and prone to dryness and roughness. 5. Weight loss partial eclipse Extreme weight loss partial eclipse will also make the skin dry. When the skin can't get enough nutrition, it will lose elasticity and moisture, making the skin dry and fragile. Xeroderma is also called xeroderma. 6. Other reasons: indoor heating temperature is too high, bathing with overheated water, using irritating soap or detergent, and endocrine changes, such as decreased estrogen secretion in postmenopausal women. 1. Grease moisturizing to prevent water evaporation is the best moisturizing product, commonly known as vaseline. Gasoline will not be absorbed by the skin, but will form a moisturizing barrier on the skin, making it difficult for the skin to evaporate and lose water, and at the same time protecting the skin from foreign bodies. Because it is extremely insoluble in water, it can be attached to the skin for a long time, so it has a good moisturizing effect. The moisturizing skin care products containing vaseline include Ponzi cold cream and Estee Lauder moisturizing lotion. Its disadvantage is that it is too greasy and only suitable for extremely dry skin or extremely dry winter. Young people who are not suitable for oily skin will clog pores and cause acne and acne. Besides vaseline, there are high-viscosity white wax oil, various triglycerides and various ester oils. Skin care products containing anti-evaporation humectants basically contain these ingredients, which are suitable for night cream and nutritional cream for extremely dry skin at night. 2. Absorb moisture from outside. The most typical moisturizing products are polyols, and the oldest are glycerol, sorbose, propylene glycol and polyethylene glycol. This kind of substance has the function of absorbing water from the surrounding environment, so it has a good moisturizing effect on the skin under the condition of high relative humidity. However, in the cold, dry and windy climate with low relative humidity, it is not good for the skin, but will absorb the moisture in the inner layer of the skin, making the skin drier and affecting the normal function of the skin. Many skin care products, such as lotions, lotions, creams and other skin care products, contain such ingredients to a certain extent, which can help the products to keep moisture and prevent their rapid water loss. On the one hand, it can stabilize the product, on the other hand, it can help absorption. Moisturizing skin care products containing such ingredients are suitable for use in summer, late spring, early autumn and southern areas with high relative humidity, especially in autumn and winter in the north. Skin care products containing glycerol include CD skin care lotion and Kaiser moisturizing cream to prevent dry epidermis. 3. Moisture moisturizing combined with moisture This moisturizing product is neither oil-soluble nor water-soluble. It is hydrophilic and soluble in water. It will form a net structure, and free water will be combined in the net, so that free water will become combined water, which is not easy to evaporate and lose, thus achieving the effect of moisturizing. It will not absorb water from the air or the surrounding environment, nor will it clog pores. Hydrophilic but not greasy, it is refreshing to use. It is a relatively advanced moisturizing ingredient, suitable for all skin types and climates, and can be used at night and day. The ingredients of this moisturizing cream are collagen, elastin and hyaluronic acid. 4. Repair of keratinocytes Moisturizing and repairing dry skin No matter what kind of moisturizing skin care products are used, the effect is always short-lived. It is better to improve the protective function and moisturizing function of the skin itself to achieve more ideal results. Vitamin E can gather in the stratum corneum of the skin, help the stratum corneum to repair its waterproof barrier and prevent the evaporation and loss of water in the skin and stratum corneum. Vitamin e is absorbed into the dermis of the skin within 6 to 24 hours after rubbing, protecting the cell membrane of the skin. Vitamin A is an important component to regulate the growth and activity of skin cells, which can increase the elasticity of skin and help increase the thickness of epidermis and dermis. Provitamin B5, also known as panthenol, can promote the regeneration of fibroblasts and help tissue repair. Vitamin C can promote the synthesis of collagen, make the skin fuller and prevent the formation of wrinkles. Fruit acid can remove the cuticle that has lost its moisturizing function in the outermost layer of skin, so that the newly born keratinocytes can naturally exert their moisturizing function and improve the moisturizing degree of skin. It's a repair moisturizer. 2. Reasonable diet, adequate sleep, moderate exercise and pleasant mood are also the keys to skin care and beauty. Some women go on a diet to lose weight, but they don't know that women who often lack animal protein and fat in their diets will have sallow, dull and poor elasticity. However, most people who are addicted to the sweetness of fat meat have large pores and greasy skin, and are prone to sores. Therefore, a reasonable diet structure and a combination of meat and vegetables can balance nutrition. Ensure adequate sleep, especially make good use of the best skin repair period from 9 pm to 2 am. Women who are used to nightlife will not help their skin even if they sleep more during the day. Moderate exercise, especially aerobic exercise, can promote blood circulation and metabolism of the skin, which is beneficial to skin bodybuilding. In addition to the above, having a good mood is also indispensable. Usually, we should also pay attention to getting rid of some bad facial expressions, such as frowning and pouting, to avoid premature wrinkles. If you want to have enviable skin, the daily cleansing and skin care process is also very important. Young girls had better not wear makeup because they don't have the courage to face the sky. Women who are used to makeup should pay special attention to cleaning their skin. If you are satisfied with the answer, give me the best answer!
