In her Beauty King, Big S said, "For most people with dry face and body, I recommend them to drink collagen, which can improve your whole body skin problems, delay aging and dilute pigmentation and wrinkles." Because of such a sentence in the big S book, collagen has been popular all over the world for a time, and various beauty brands have launched their own products. Beauty salons, large and small, have also launched their own whole-body collagen supplement services, and even health care products are filled with shelves. No matter whether imported or made in China, the slogan 10 is one month younger. So is collagen really as effective as big S said? Does everyone really need collagen supplements? Does it work whether it is eaten or painted? Collagen is a kind of polymer protein, which is the main component of skin. Collagen accounts for about 72% in skin and 80% in dermis. Can keep the skin firm and elastic, form a fine elastic net in the skin, and lock in moisture. 22-year-old women's skin collagen synthesis ability began to decline, collagen began to age and lose, and the content decreased year by year. At the age of 25, it entered the peak of brain drain, and at the age of 40, its content was less than half of 18. Therefore, even if you want to make up, you should start to make up at the age of 25. When you make up, you should divide it into boys and girls, because due to physiological factors such as menstruation and childbirth, the loss of collagen in women is about 2.5 times that of men. Therefore, the age for boys to make up lessons can be postponed for one or two years. So, will eating those nutritional products containing glial protein really make you one month younger 10 years old? I think we consumers just listen to this slogan, even those consumers who really spend money to sell it just hold the idea that it is better to make up than not to make up. After all, it's just a health product, not an elixir. In fact, this truth is also said in the book of Big S that "dry collagen of skin should be wiped, not drunk or eaten". I think this is also the reason why those beauty salons offer the whole body collagen supplement service. Then we really rub collagen on the whole body skin later, and it will get up and replenish. Is it really better than eating? Here is a molecular weight. As we all know, the stratum corneum on the surface of our skin has a small pore size and is a good protective layer, which can keep moisture and protect the skin from bacteria. It can be considered that those things rubbed on the body are difficult to enter the skin, and only oligopeptides with low molecular weight can directly penetrate the stratum corneum and dermis and be quickly absorbed by the skin. So what is oligopeptide? Here we tell you that only collagen below 1000 dalton can enter our skin and be absorbed by the human body. This is what Niu Er, another beauty master in Taiwan Province, said: "The general collagen supplement is just a comfort to people." . Because of this, the molecular weight of most products on the market now is higher than 1000 dalton. In fact, eating is the same. All protein are linked by amino acid molecules with peptide chains. Most protein consists of more than 300 amino acid molecules. Scientists refer to biochemical substances with amino acids above 10 and below 100 (molecular weight 1000DAL- 10000 dal) as "peptides", and those below 100 as oligopeptides (molecular weight less than1) Oligopeptides can be absorbed directly in the duodenum without being digested by gastric juice, and the price of oligopeptides is also very different from other kinds, so the raw materials of a bottle of nutritional products with tens or hundreds of yuan are definitely not oligopeptides that can be well absorbed by the human body, so the effect of supplementation can be imagined. Finally, I want to ask big S a question. Do you want to recommend the source of collagen to everyone? At present, the raw materials of collagen products produced in the market mostly come from animal skins such as pigs and cattle. In recent years, with the occurrence of many epidemics such as mad cow disease and foot-and-mouth disease, the potential danger of extracting collagen from these objects has increased. Europe, America, Japan and other countries have issued some regulations restricting the extraction of collagen from cattle and other animals for food and medicine. The main raw material of fish collagen comes from fish, which has high biological safety and does not have these potential threats. Collagen oligopeptide extracted from fish scales is pure natural and pollution-free high-quality collagen. Because some mm should ask more questions when choosing to eat or make a mask, otherwise spending money without saying that the effect is not good will not be worth the loss. Having said these indicators, you may be thinking that some imported brands have reached the standard. I've seen friends bring this back from a certain country. In fact, we don't have to blindly pursue imports. Some imported products are also produced in China, packaged and sold abroad. For example, fish collagen oligopeptide products produced by Hubei Ruibang Biotechnology Co., Ltd. are specially produced in Japan, Poland, South Korea and other countries. We are not easy to find in the market, but online shopping is not difficult now. You can find it at home. Finally, teach MM to make a moisturizing mask with the formula of big S, and you can achieve the effect of going to the beauty salon at home: 3 grams of collagen oligopeptide powder, pure rose dew 15ML, 3 tablespoons of yogurt and a piece of mask paper. Apply your face for 20 minutes, and add two drops of your favorite essential oil to Xiangxiang MM.
