Face is the place that can best reflect a person's qi and blood. The skin is shiny and ruddy, and it needs adequate blood supply. Iron is one of the main components of heme in blood, so eat more foods rich in iron. Such as animal liver, egg yolk, kelp, laver, etc.
2. Keep plenty of water.
Water is a very important substance in the human body and plays an important role in maintaining metabolism. The water content of human tissue fluid is 72%, and that of adults is 58%-67%. When the body moisture decreases, the skin will be dry, the secretion of sebaceous glands will decrease, which will make the skin lose elasticity and even wrinkle. In order to ensure water intake, girls should drink about 1200ml every day.
3. Eat more fruits and vegetables and supplement vitamins.
There are many kinds of vitamins, many of which are the best natural substances for antioxidation. Vitamins play an important role in preventing skin aging and keeping skin delicate and moist. Japanese scholars have found that vitamin E plays an important role in skin anti-aging. Because vitamin e can destroy the chemical activity of free radicals, thus inhibiting aging. Vitamin E can also prevent lipofuscin from depositing on the skin. Scientists have found that the formation of lipofuscin is related to lipid peroxide. Foods containing more vitamin E include cabbage, sunflower oil and rapeseed oil. Vitamins A and B 2 are also indispensable substances for smooth and moist skin. When the human body lacks vitamin A, the skin will become dry, rough and scaly; If vitamin B2 is lacking, there will be oral milk, chapped skin, desquamation and pigmentation. Foods rich in vitamin A include animal liver, cod liver oil, milk, cream, eggs and orange-red vegetables and fruits. Foods rich in vitamin B2 include liver, kidney, heart, eggs and milk.
4. Eat more alkaline food.
Alkaline food is good for health. Fish, meat, poultry, eggs and grain eaten in daily life are all physiologically acidic. Strongly acidic foods will increase the contents of lactic acid and uric acid in body fluids and blood. When organic acids cannot be excreted in time, they will erode sensitive epidermal cells and make the skin lose its tenderness and elasticity. In order to neutralize the acidic components in the body, we should eat some physiological alkaline foods, such as apples, pears, oranges and vegetables.
5. Increase the intake of foods rich in collagen and elastin.
Collagen can make cells plump, thus filling the skin and reducing wrinkles; Elastin can enhance the elasticity of human skin, thus making the skin smooth and elastic. Foods rich in collagen and elastin include pig's trotters, animal tendons and pigskin.
