1. Moisturizing: Collagen peptide contains hydrophilic natural moisturizing factor, which directly forms collagen after entering the body, keeping skin moist and tender at all times.
2. Nutrition: Collagen peptide has strong permeability to the skin, can combine with skin epithelial cells through the stratum corneum, participate in and improve the metabolism of skin cells, and strengthen the collagen activity in the skin. It can maintain the integrity of moisture and fiber structure of stratum corneum, improve the living environment of skin cells, promote the metabolism of skin tissues, enhance blood circulation, and achieve the purpose of moisturizing skin.
3, brighten the skin: the luster of the skin depends on the water content, and the good water retention ability of collagen makes the skin moist and shiny, giving off a healthy luster.
4. Firming skin: Collagen peptide is absorbed by skin and filled between dermal layers of skin, which increases skin firmness, produces skin tension, shrinks pores and makes skin firm and elastic.
5. Anti-wrinkle: The plump collagen layer in the dermis supports skin cells, and combines the functions of moisturizing and inhibiting wrinkles to achieve the effect of stretching thick lines and diluting fine lines.
6. Repair: Collagen peptide can directly penetrate into the bottom layer of skin, and has a good freshness with surrounding tissues, which can help cells to make collagen and promote the normal growth of skin cells. At the same time, it also has the functions of diminishing inflammation and renewing skin.

Effects of different peptides:
Protein is ingested by human beings through food, and these protein are the source of many bioactive peptides. Some active peptides derived from food proteins are naturally occurring, while others are enzymatic hydrolysis products catalyzed by protease.
1, immunoactive oligopeptide. Egg protein (eggs of various birds), soybean protein, rice protein, wheat protein, corn protein, sorghum protein and millet protein, which are human food proteins, can be hydrolyzed by appropriate enzymes and reasonable enzyme formulas to produce peptides with immune activity. Some peptides can not only phagocytize macrophages, but also inhibit the growth of tumor cells.
2. Antihypertensive peptides. In the physiological process of human body, renin (an enzyme) released by renal periglomerular cells enters the blood, and an az globulin (angiotensin) in plasma is converted into angiotensin II by invertase when it passes through pulmonary circulation, which can directly strengthen myocardial contractility and increase heart rate, and can also directly act on vascular smooth muscle.
From the point of view of nutrition and treatment, the inhibitor of enzyme is the key point in this process. Many enzymatic hydrolysates in protein contain angiotensin inhibitors.
3. Peptides for transporting trace elements. The formation of casein phosphopeptides during biological digestion is related to the transport of trace element peptides. Casein phosphopeptide can form a soluble complex with calcium ions to prevent the concentration of calcium and phosphorus from decreasing.
Casein phosphopeptide can increase the concentration of soluble calcium in small intestine, thus promoting the passive absorption of calcium in small intestine. In addition to complexing with calcium ions, it can also be complexed with other elements, such as iron, zinc, magnesium, copper and other elements beneficial to human health.
4. Opioid active peptides. Many kinds of food proteins will produce opioid active peptides after enzymatic hydrolysis. Such as casein, other protein of milk, milk casein, human milk protein, wheat protein and rice protein, whose main function is to relieve pain.
Different from the analgesic drugs currently used, it enters the human body through digestive organs without any toxic or side effects. Opioid active peptides in wheat gluten are the results of in vitro enzymatic hydrolysis of pepsin and microbial neutral protease.
5. Growth-promoting peptide. This peptide can stimulate the growth of bacteria beneficial to human body, especially lactic acid bacteria. Such as the enzymolysis products of insulin, casein, ribonuclease and soybean protein.
6. Cyclic peptide CHP. Cyclic peptide CHP, as a kind of peptide with special structure, is listed as the research object because of its diversity of biological activities. The cyclic peptide CHP is partly derived from TRH (thyrotropin releasing hormone in hypothalamus).
But also widely distributed in human central nervous system and gastrointestinal tract. Exogenous administration of CHP can obviously show many biological activities, for example, it can show satiety in mice and inhibit the secretion of insulin and glucagon.
