The climate in winter is dry, so many people will have dry skin. The humidity of the air is greatly reduced, the skin becomes dry and itchy, and the ability to absorb and moisturize is not as great as before. After applying moisturizer, the skin will start to dry. ?
Dry: the enemy of winter skin
The skin is divided into epidermis, dermis and subcutaneous fat. The outermost layer of the epidermis is the stratum corneum, and due to the water absorption and barrier function of the stratum corneum itself and the natural moisturizing factors contained in the stratum corneum, that is, amino acids, lactate, and sugar, the stratum corneum is kept in a certain degree. The amount of water keeps the skin moist. The appearance of the skin is related to the moisture content of the stratum corneum. The normal skin stratum corneum usually contains 10% to 30% of water to maintain the softness and elasticity of the skin. However, as the age increases, the moisture content of the skin's stratum corneum will gradually decrease, and when the skin's moisture content of the stratum corneum is less than 10%, the skin will appear dry, tight, rough and desquamation.
What are the causes of skin moisture loss, resulting in dry skin and loss of luster? In general, the internal and external conditions that cause the skin to lose its natural moisturizing structure are:
â— With age, skin aging, its moisturizing effect and barrier function gradually weakened, natural moisturizing factor content decreased;
â— dry and cold climate, low humidity, such as autumn and winter;
â—Some skin lesions, such as psoriasis and ichthyosis;
â— Environmental and chemical factors, such as detergents, soaps, detergents and other organic solvents such as alcohol, as well as long-term air-conditioning environment;
â— diet and sleep habits, such as partial eclipse, drinking water, insomnia, etc.;
â— dry skin.
Since the skin is in direct contact with the external environment at all times, if it is not protected, water shortages will be more or less directly affecting the appearance of the skin. At this time, in addition to ensuring a normal and healthy diet to ensure the supplementation of protein and vitamins, as well as to avoid external adverse factors and actively treat skin disorders, it is also necessary to use suitable moisturizing cosmetics as needed.
Prevent dry skin should pay attention to the following points:
1, increase the intake of various vitamins. Vitamins play an important role in preventing skin aging and protecting delicate skin moisture. Such as vitamin A deficiency, can cause the skin elasticity to drop, become rough; In the absence of vitamin B2, there will be dry lips, skin cracking and so on. Foods rich in vitamin A: such as animal liver, cod liver oil, lean meat, eggs and orange-red vegetables and fruits. Rich in vitamin B2 rich foods such as yeast, fish, eggs, beans, scutellaria, crabs and so on. In addition, vitamin E has anti-oxidation effect on the cell membrane, which has a debilitating effect on the skin. Foods containing more vitamin E such as: sesame oil, peanut oil, soybean oil, cabbage and so on.
2. Eat foods that contain more collagen and elastin. Collagen can make cells become full, so that the skin is rich, wrinkles reduced, usually can be properly eaten tendons and pigskin, chicken skin and other foods.
3, increase the intake of trace elements. Need to provide adequate blood, iron is one of the main components of hemoglobin in the blood, eat more iron-rich foods, such as animal blood, egg yolk, meat and so on. Natural iron in food is a high-valent iron with very low solubility and cannot be absorbed directly. It can only be absorbed by the gastrointestinal tract in an acidic environment. Therefore, when adding iron, increase the amount of vitamin C-rich foods such as tomatoes, green peppers and hawthorn. Zinc deficiency will make the skin dry and rough, prone to acne, zinc-containing foods such as oysters, malt, walnuts, seeds and so on. In addition, pearl contains a variety of trace elements, amino acids and proteins, can improve the skin's nutritional status, reduce skin aging and wrinkling.
4, pay attention to alkaline food intake. To reduce the intake of animal fats, meats and sweets in the diet. These physio-acidic foods are oxidized and decomposed in the body and increase the levels of lactic acid and uric acid in body fluids and blood, making the skin rough and greasy. In order to neutralize excess acidic substances in the body, you should eat more physiological alkaline foods, such as Fresh fruits and vegetables to improve the skin's supply, make the skin smooth and moist.
5, always pay attention to drinking water. The degree of delicate skin moisture is closely related to its moisture content. When the body's water content decreases, dry skin and sebaceous glands are reduced in secretion, causing the skin to lose its elasticity and even wrinkles. Therefore, for the sake of skin fitness, you should adhere to the right amount of drinking water every day.
