Cosmetic effect of cosmetic peptide in cosmetics

The biological activity of peptides depends on their amino acid composition and sequence. Almost all physiological processes in human body are regulated by peptides or proteins composed of specific amino acid sequences. Therefore, bioactive peptides have become a new direction and idea for cosmetics research and application, and their functions are becoming more and more subdivided, such as anti-aging, anti-allergy, repair, anti-oxidation, anti-edema, promote hair regeneration, inhibit melanin production, breast enlargement, weight loss and so on.
Skin is the body's natural barrier against external environmental damage, and has a certain protective effect on external stimulation, which benefits from the protection of the skin's dense cuticle. But it also blocks the nutritional components of cosmetics on the skin surface, nutrients need to penetrate the cuticle cell membrane to enter the dermis, macromolecules and fat-soluble substances only a small amount can be absorbed through pores, pore. So we usually use cosmetics, most of them just stay on the surface of the skin, and the bioactive cosmetic peptides can easily penetrate the cuticle space into the dermis, thereby playing a role.
Originally used by some European and American cosmetics directly in the product, the mechanism of action is similar to that of protein, can promote the proliferation of collagen, elastic fiber, polysaccharide and hyaluronic acid, improve skin moisture, increase skin thickness and reduce fine lines.  Because of the different kinds of amino acids, they can play different roles to meet the different functional needs of the skin.
