Skin color is an important symbol of bodybuilding. Black and white skin is related to the amount of melanin in the skin. The adjustment of diet can reduce the synthesis of melanin and help dull skin to whiten. (1) Eat less food rich in tyrosine. Because tyrosine is the basic substance of melanin. In other words, melanin is converted from tyrosine by tyrosinase. If the intake of tyrosine is less, there will be less basic substances for synthesizing melanin, and the skin will turn white. So eat less food rich in tyrosine, such as potatoes and sweet potatoes. (2) Eat more foods rich in vitamin C. Chemical experiments have proved that a series of reactions of melanin formation are mostly oxidation reactions, but adding vitamin C can block the formation of melanin. Therefore, eat more foods rich in vitamin C, such as jujube, fresh jujube, tomato, Rosa roxburghii, orange and fresh green leafy vegetables. (3) Pay attention to foods rich in vitamin E. Modern scientific research has proved that vitamin E is an antioxidant in human body, especially in fat, and can inhibit the peroxidation of unstable compounds such as unsaturated fatty acids. Lipoprotein in human body is a peroxide of unsaturated fatty acids. Vitamin E can inhibit their peroxidation, thus effectively resisting the deposition of lipofuscin on the skin and keeping the skin fair. At the same time, vitamin E also has anti-aging effect. Foods rich in vitamin E include Chinese cabbage, cauliflower, sesame oil, sesame, sunflower seed, rapeseed oil, sunflower seed oil and so on. Snow muscle whitening and strengthening whitening scheme is a thing all year round, but it is always the most attractive interest and concern in spring and summer every year. Therefore, all brands have made great efforts to promote their new whitening products and the latest whitening technology during this period. This provides people with more choices, but it is also confusing: who should I choose? In fact, the demand for whitening is also divided into different levels: uniform skin color, elimination of dark yellow, prevention of tanning, and fading spots ... Today, we will combine various whitening technologies to discuss how to restore even and fair skin. Why not? Glossy: keratin accumulation At present, domestic whitening products can't whiten naturally dull skin, so it's a bit futile to search for "whitening products" as white as big S, but no matter whether the skin is dull or fair, it may be unsatisfactory: it doesn't look beautiful! That's because-it was dark. Eliminate dullness and make your skin bright and dark, and you will feel "white" beautiful! Eliminating dullness with skin care products is very simple-exfoliation, a familiar term. However, this is only a "temporary solution, not a permanent cure". It is best to investigate the causes of skin blackening: lack of sleep, overwork, bad mood and so on. , will inhibit the metabolism of the skin, become slow, leading to the accumulation of old waste keratin. If too much ultraviolet radiation is not protected, the skin will quickly start the self-protection mechanism and thicken keratin to "try its best" to stop ultraviolet radiation-stopping it from the source of keratin accumulation is the fundamental way to eliminate dullness. Huang: The accumulation of toxins and yellow complexion also have a lot to do with lack of sleep, being too tired and being in a bad mood-there is no way. If you want to have "snow muscle and ice skin", you have to "pamper yourself". Yellow skin color is also related to unhealthy lifestyle: smoking, drinking, being in a closed environment for a long time, lack of fresh air and so on. Similarly, to "eliminate pornography" from the source, skin care products are not omnipotent; But it is absolutely impossible to leave skin care products-at least you can make a "shiny surface". Not all whitening products can go yellow, and those that can go yellow are not necessarily in the whitening series. You should distinguish when choosing. Yellowing is caused by free radicals-when the skin's metabolism slows down and its self-repair function declines, under the stimulation of ultraviolet rays, free radicals tend to flood, leading to poor skin microcirculation, insufficient oxygen supply to cells and accumulation of toxins, which makes the skin yellow. Therefore, the selected skin care products should pay special attention to detoxification and antioxidant functions. Black: melanin accumulation Ultraviolet radiation is the main reason for activating melanin and causing pigment deposition. The formation of pigmentation is due to the deposition of melanin in the basal layer (between stratum corneum and dermis), and then slowly emerge from the skin surface; Uneven skin tone, tanned skin, or looking dirty and colorful are all melanin deposits on the epidermis. There is more oil in the pores of oily skin, which makes it easier to absorb ultraviolet rays, and melanin will accumulate around the pore wall, making the pores look darker and more obvious; The overall skin color also tends to be dark. Therefore, in order to dilute the stain, we must use whitening essence, go deep into the basal layer of the skin, and block the root of melanin; In order to even the skin color and restore whiteness, we should choose a whitening emulsion/cream with strong functions, which mainly acts on the epidermis and can also get results. Did you find out? The same enemy that causes black, yellow and black skin is ultraviolet rays. Therefore, in order to get "snow muscle and ice skin", we must first "block" ultraviolet rays-full spectrum sun protection, sun protection every day! Cleanliness and exfoliation are accumulated in whitening series, and there are often many products with exfoliation effect, but the most important thing is cleaning products. You don't have to expect whitening facial cleanser and whitening makeup to whiten your skin. The whitening ingredients will be washed away by water in a short time, and the content is too small to play a whitening role. However, their function of removing old and waste keratin from the skin surface is clear. Therefore, if your skin is not dark or thin and sensitive, it is unnecessary and inappropriate to use whitening facial cleanser and lotion with exfoliating function every day. If you need to exfoliate, you would rather choose mild exfoliating (or exfoliating) products for weekly care, such as FANCL moisture penetration mask, Clinique rejuvenation and softening mask, biotherm wisdom whitening and freckle removing mask, etc. , and exfoliate regularly or only when necessary. If your skin is "strong" and prone to keratin accumulation, whitening facial cleanser and whitening emulsion with exfoliating effect are good choices-if you want to strengthen hydration, you can also add moisturizing liquid or moisturizing beauty liquid with better moisturizing after whitening emulsion. At the same time, when choosing whitening facial cleanser, we should also pay attention to adapt to our skin-there was only one facial cleanser in the previous whitening series, but this year's Clinique Extraordinary Whitening Series and Oprah Time and Space Whitening Series. , subdivides the different cleaning needs of dry to oily skin, and is safer to use. -This year's whitening essences mostly emphasize light spots, but in order to "effectively lighten spots" or achieve the immediate effect of "whitening quickly", some acidic components and exfoliating components in whitening essences are not so safe for some skin; If it causes sensitivity, it will cause pigment precipitation. Therefore, if you just want to pursue even and fair skin and have no requirements for light spots, you should choose mild and safe whitening essences: FANCL freckle-removing whitening essence, DHC whitening essence, LAMER whitening essence, Irina Kaptelova Bo- Ya Dun silk whitening essence, SOFINA whitening essence, BOBBIBROWN whitening essence and so on. , all based on stable vitamin C derivatives and plant extracts, can inhibit and reduce melanin without shedding. As we said, all lotions/creams are, in the final analysis, moisturizers. Therefore, when we choose whitening milk/cream, we must not ignore the moisturizing performance of the product-if we can't keep the skin moist, it will not only reduce the whitening effect, but also have side effects on the skin. In the past, whitening products were mainly designed for skin in spring and summer. At this stage, the skin is prone to oily sweating, so whitening lotion/cream is often dry. Nowadays, many brands pay more and more attention to the importance of moisturizing, as well as the annual demand for whitening, and the moisturizing property of products is greatly strengthened. As long as it is not extremely dry skin, Irina Karp Tairova Bo-Ya Dun series, Clarins series, Estee Lauder series, Clinique series and SK-II series can basically meet the moisturizing needs. At the same time, these series also have strong oxidation resistance, "anti-black" and "anti-pornography". SK-II whitening and rejuvenation repair cream contains intelligent photosensitive vitamin capsules. When exposed to ultraviolet rays, vitamins C and E will be gradually "slowly released", which can keep the activity for a longer time. Many whitening day creams/creams also add a sunscreen effect to provide the most basic ultraviolet protection for "lazy people" who have no sunscreen habits. However, if you are not a lazy person, you can use their night cream, such as Clarins Clear Whitening Repair Night Cream, Oprah Winfrey Night Lotion/Milk/Cream, Lan Zhi Clear Whitening Repair Cream and so on in the morning and evening. Adding a layer of high-index full-spectrum sunscreen during the day can not only protect more comprehensively, but also help to supplement sun protection. In order to achieve better whitening effect, especially if whitening essence is not used, it is necessary to use whitening (detoxification) mask together. Because the mask often contains a high concentration of whitening (detoxification) essence, the osmotic pressure of the mask is also more conducive to the effective ingredients being deeply absorbed by the skin. After applying the mask, you can get obvious whitening effect immediately. If you continue to use it regularly, you can continue this immediate effect. Any mask has the function of deep cleaning-when applying the mask, the skin is temporarily isolated from the air, which increases the temperature of the skin and accelerates metabolism. With the washing or peeling of the mask, the dirt and metabolites in the deep skin are also taken away. So any whitening mask can be "darkened". If you have thin and sensitive skin, you should also avoid using a whitening mask that emphasizes "removing aging keratin containing melanin" (actually exfoliating) or "peeling off old waste keratin" by tearing, which may be too "irritating". If you want to strengthen the "anti-pornography" effect, you can choose Estee Lauder Crystal Huanbaiyingcai Cleansing Mask and biotherm Active Oxygen Cleansing Mask to effectively eliminate skin toxins. If you use the whitening mask and the purifying and detoxifying mask alternately 2~3 times a week, you can whiten and brighten your skin in all directions. Kiwi, strawberry, sesame, kelp and sweet potato not only whiten the skin, but also help to lose weight! Red, yellow and orange pigments contained in carrots, tomatoes and various vegetables, such as carotenoids, can inhibit the production of melanin, and their efficacy is much higher than that of lipid arbutin (hydroquinone glucose) used in whitening cosmetics. Pigments such as carotenoids will be transported to the skin after being absorbed by the intestine, so drinking vegetable juice often can keep the skin white. In addition, because melanin is the root of freckles, vegetable juice can also prevent freckles. In addition, excellent cheese can also improve the skin. 1. Broccoli-It is rich in vitamin A, vitamin C and carotene, which can enhance the skin's anti-damage ability and help maintain skin elasticity. 2. Carrots-Carotene helps to maintain the normal function of skin cells and tissues, reduce skin wrinkles and keep skin moist and tender. 3. Milk is skin's favorite food at night, which can improve skin cell activity, delay skin aging, enhance skin tension and eliminate small wrinkles. 4. Soybean is rich in vitamin E, which can not only destroy the chemical activity of free radicals, inhibit skin aging, but also prevent pigmentation. 5. Kiwifruit-rich in vitamin C, can interfere with melanin production and help eliminate freckles on the skin. 6. Tomatoes-contain lycopene, which helps to smooth wrinkles and make skin tender and smooth. Eating tomatoes regularly is not easy to get dark circles and sunburn. 7. Honey-contains a lot of amino acids, vitamins and sugars that are easily absorbed by the human body. Regular consumption can make the skin rosy, tender and shiny. 8. Meat skin-rich in collagen and elastin, can make cells plump, reduce wrinkles and enhance skin elasticity. 9. Salmon-the fatty acids in it can eliminate a bioactive substance that destroys skin collagen and moisturizing factors, prevent wrinkles and prevent skin from becoming rough. 10. Kelp-rich in minerals, it can adjust the pH of blood and prevent skin from crossing. Chinese medicine believes that people must start with food, adjust their bodies and expel toxins. Only by removing the yellow gas and black gas from the skin can we have a healthy, whitening and moisturizing complexion. Amaranth can remove melanin and acne on the face. Because amaranth helps to excrete, it can expel pus, remove dampness and detoxify, and remove skin sores, especially intestinal dampness. Boil amaranth and garlic for half an hour to make thick soup, which can make the skin smoother. Amaranth is mild and can be drunk every day. It is impossible to moisten the lungs, beautify the skin and whiten the lotus and lily porridge overnight. To make the skin white and red, we must first strengthen the function of the lungs. Long-term consumption of lotus lily porridge can achieve this effect. As for the weight of lotus seeds and lilies, it can be decided according to personal preference. Yang Baoling knows how to dress up and has always had the habit of drinking a glass of fresh milk every day. Her skin is smooth and fair. Pauline admits that fresh milk can really promote the growth of skin cells and make her skin smooth. But she also said that black sesame paste is more effective than fresh milk. Eating too much will make your skin slippery, and less wrinkles will make your skin ruddy and fair. However, the calorie of a bowl of sesame paste is almost as high as that of half a bowl of white rice, and it is enough to eat it three times a week. Sesame paste has the function of accelerating metabolism, and eating tomatoes can make the skin color more rosy and smoother.
