How can we identify and judge the quality of collagen?

China health care association experts told reporters that collagen is the structural protein of extracellular matrix, not a single substance. According to the size and structure of molecules, they can be divided into many types. For example, pig's feet, pig's skin and pig's bones all have a thick layer of gum, which tastes soft, elastic and quite sticky. This is collagen. But only "oligopeptide" in collagen, that is, collagen with molecular weight less than 1000, can beauty beauty and enhance bone health. Macromolecular collagen can't penetrate into dermis and can't improve skin structure.

Some manufacturers sell ordinary macromolecular collagen as oligopeptide. These macromolecular collagen proteins are usually gelatin and are used as thickeners. If consumers eat macromolecular collagen, it may not only fail to play a cosmetic role, but will eat bad stomach. At present, many collagen products on the market are scratching the edge, especially in the online shopping market, which is even more mixed. Therefore, consumers must choose carefully, and it is best to buy in a regular online electronic mall such as mountain products Bar.

In addition, the price of collagen products varies greatly according to the different raw materials and processes. Generally, pigskin makes tens of thousands of yuan a ton of collagen and hundreds of thousands of yuan a ton of oligopeptides. Due to the lack of basic knowledge of ordinary consumers, businesses often change their concepts and label ordinary collagen products with the function and efficacy of oligopeptides.

Beauty and health care should choose high-quality oligopeptide products and be wary of hydrolyzed leather protein products. At present, the retail price of oligopeptide collagen products is lower than that of 300 yuan, and most of them are unreliable.

Introduce a simple method: apply the product on the back of the hand to see if it can be absorbed by the skin. If you feel uncomfortable, the skin surface will be covered with a sticky substance, or even form a film or "shell", which is macromolecular collagen, not oligopeptide.
