How to prevent and improve the dry and itchy skin caused by this dry and cold weather? In fact, for dry and itchy skin caused by seasonal changes, the most important thing is prevention, because prevention beforehand is often much more effective than treatment afterwards, which means that effective measures should be taken in time before symptoms appear to avoid skin problems. The key to prevent skin dryness and itching is to keep skin moisture, reduce the loss of moisture and oil in stratum corneum and protect sebum function. Suggestions can be made from the following aspects: 1) 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 compared with 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). Moreover, it is necessary to reduce the number of baths, shorten the bathing time, and 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. 2) After bathing, when the skin is not completely dry, immediately apply moisturizing body lotion, especially in the particularly dry parts such as limbs, which can help the skin to restore water-oil balance and form a thin film on the skin to 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. 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 and tibia is the part with the least sebaceous glands in the whole body, so it is most prone to itching and dandruff, while the arm is often exposed to the air and is most prone to dryness. 3) The topic of body lotion has been discussed a lot in the forum. I recommend several lotions with mild ingredients to you. La roche-posay Body Milk: Its ingredients mainly contain the extract of the plant "avocado" in addition to glycerin and other commonly used humectants; Avocado is rich in glyceric acid, protein and vitamins, and it is moist but not greasy. Because it is closest to the human sebum membrane, it can not only soften and moisturize the skin, keep the skin soft and elastic, but also accelerate the healing of skin lesions, and has the skin care function similar to the natural "sebum membrane" of human skin. As long as a thin layer is applied to dry skin, it can effectively moisturize the skin and relieve itching. Neutrogena Body Cream Body Moisturizing Lotion: Rich in glycerin and natural sesame oil, it can quickly moisturize dry muscles and prevent water loss. Excellent moisturizing ability, can provide moisture for skin for more than 8 hours. L 'Occitane Shea Butter L 'Occitane Shea Butter Body Milk: It contains 65,438+05% shea butter, natural honey and apricot oil, and contains essential fat components and vitamins for the skin, which can maintain the natural moisturizing level of the skin, make the skin light, soft and easy to absorb, keep soft and shiny all day after use, and bring efficient nourishing, moisturizing and protective effects. It is suitable for any skin, even sensitive skin in dry season or time. Especially shea butter, which is rich in unsaponifiable ingredients, has deep moisturizing effect, which can not only prevent drying and cracking, but also further restore and maintain the natural elasticity of skin. Biotherm Body Moisturizing Emulsion: It contains natural mineral water and is rich in minerals. Its unique ingredient PERTARE can make moisturizing molecules fully absorbed by the skin, replenish moisture, effectively nourish the skin, and make the skin feel no longer dry and tight. 4) Reduce the use frequency of exfoliating products and avoid damage to skin protective film caused by excessive exfoliation. 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. 5) Pay attention to sun protection during the day. Although the sunshine in autumn is not as severe as that in summer, the power of ultraviolet rays in autumn can not be underestimated, because the concentration of atmospheric ion layer in autumn is thinner than that in summer and the amount of ultraviolet rays absorbed is less than that in summer, so ultraviolet rays are 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 don't forget to use sunscreen to protect the skin after applying moisturizing lotion during the day. 6) In order to avoid skin moisture evaporation caused by dry indoor air, the hardness of the room should be improved as much as possible, and the humidity is usually kept 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 economic measures, such as fattening in the room, or putting a few fish tanks and hydroponic plants, which is also a good choice, which can keep the humidity of the palm of your hand in the room and help keep your 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. 7) Personal clothes should be made of loose cotton products, preferably sweat-absorbent and breathable, to avoid contact friction or skin itching caused by 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. Especially in cold weather, some people like to wear thermal underwear, but it should be noted 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 achieve the purpose of keeping 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. In addition to choosing suitable skin care products, internal conditioning is also very important, and attention should be paid to rest and proper psychological pressure adjustment. In terms of diet regulation, we should pay more attention to drinking more water to replenish the water lost by the body and increase the water supply of the skin. Pay attention to balanced nutrition and eat more water-rich foods such as fresh fruits and vegetables, milk and soy milk. You can also often eat sesame oil, soybeans, peanuts and other foods, which contain unsaturated fatty acids, such as linoleic acid. But if the human body lacks linoleic acid, the skin will become dry and the scales will become thicker. Vitamin intake is also very important for the prevention and treatment of skin itching, especially vitamins A, B2 and B6. When the human body lacks vitamin A, the skin will become dry, scales will appear, and even prickly papules will appear on the skin. So eat more foods rich in vitamin A, such as animal liver, carrots, rape, celery, eggs, cod liver oil and so on. Vitamin B plays a vital role in human metabolism. Lack of vitamin B will hinder metabolism, affect cell function and easily lead to skin problems such as dermatitis and acne. Foods containing vitamin B6 include: wheat bran, potatoes, peas, Chinese cabbage, beef liver, beef kidney, bananas and so on. Foods containing vitamin B2 are: soybean, yeast, animal liver, mushrooms and so on. At the same time, patients with itchy skin should avoid spicy, greasy, seafood, coffee, cigarettes, wine and other irritating foods, because these foods are irritating to the human body and skin, which may aggravate the condition of people who already suffer from certain skin diseases. For example, patients with skin suppuration should eat less sweets and alcohol; Foods such as peppers, onions, garlic, wine and strong tea can cause many reactions such as poor sleep quality and emotional instability. These psychological factors will also affect people's sensitivity to stimuli, which is more likely to cause itching, especially those with pruritic neurological disorders. The symptoms are getting worse. Diet should be light and eat less high-fat foods, because high-fat foods will increase the oil burden on the skin, especially the pores on the skin surface are easy to block; Eat less sugar food. Too much sugar will increase the proliferation of bacteria on the skin, stimulate the skin and cause itching. Seafood such as fish, shrimp and crab are "allergens" of skin itching, which can easily release active substances around skin blood vessels and aggravate skin itching, and should also be avoided. For simple seasonal skin itching, as long as the above maintenance principles are achieved, the problem of skin itching can be greatly improved or even eliminated. If severe intractable itching occurs, we should consider whether there are other visceral diseases, such as diabetes, chronic glomerulonephritis, chronic constipation, tumors and so on. , it can also lead to different degrees of skin itching. At this time, you need to go to the hospital for relevant examinations immediately.
