The biological activity of peptide depends on its amino acid composition and sequence, almost all physiological processes in human body are regulated by the peptide or protein composed of specific amino acid sequence. Therefore, bioactive peptides have become a new direction and idea for cosmetic R&D and application, and their functions are more and more subdivided, such as: anti-aging, anti-allergy, repair, antioxidant, anti-edema, promote hair regeneration, inhibit melanin production, breast enlargement, weight loss and so on.
The skin is the body's natural barrier against external environmental aggressions, and has a certain degree of protection against external stimuli, thanks to the protective effect of the skin's dense stratum corneum. Nutrients need to penetrate through the cell membrane of the stratum corneum to enter the dermis, and only a small amount of macromolecules and fat-soluble substances can be absorbed through the pores and sweat pores. Therefore, most of the cosmetics we usually use just stay on the surface of the skin, but the bioactive peptide can easily pass through the gap of the stratum corneum and enter the dermis, so as to play a role.
It can promote the production of collagen, elastic fiber, polysaccharide and hyaluronic acid, increase the water content of skin, increase the thickness of skin and reduce fine lines. Due to the different types of amino acids contained in the product, it is possible to perform different functions to meet the different functional needs of the skin.
