The role of peptides in cosmetic cosmetics
The biological activity of the peptide depends on its amino acid composition and sequence, and the various physiological processes in the human body are almost all controlled by a polypeptide or protein consisting of a specific amino acid sequence. Therefore, bio-active peptide has become a new direction and ideas for the development and application of cosmetics, and the function is more and more subdivided, such as: anti-aging, repair, anti-oxidation, anti-edema, promote hair regeneration, inhibit melanin production, breast, weight loss The
Skin is the body to resist the natural environment against the natural barrier, the external stimuli have a protective effect, which benefited from the protective effect of skin dense stratum corneum. But also the nutritional ingredients of the cosmetics block in the skin surface, nutrients need to penetrate the stratum corneum cell membrane to enter the dermis, macromolecules and fat-soluble substances only a small amount can be absorbed through the pores, sweat pores. So we usually use the cosmetics, most of them only stay in the skin surface, and has a biologically active cosmetic peptide, but it can be easier to penetrate the stratum corneum into the dermis, and thus play a role.
Peptide is initially used by some European and American cosmetics directly in the product, the mechanism of action similar to the mechanism of protein, can promote collagen, elastic fibers and hyaluronic acid hyperplasia, improve skin moisture content, increase skin thickness and reduce fine lines. Due to the different types of amino acids, which can play a different role to meet the needs of different skin functions.
The function of various cosmetic peptides:
Dipeptide: anti wrinkle
(Dipeptide Diaminobutyroyl Benzylamide Diacetate)
Local blocking nerve transmission of muscle contraction of the message, affecting the skin nerve conduction, so that facial muscles to relax, to smooth the dynamic pattern, static lines and fine lines of the effect.
Tripeptide is the earliest discovered peptide arrangement combination, is considered a growth factor, can stimulate glucosamine polyacid and collagen production. 1990 was isolated from the wound healing tissue, with the promotion of wound healing and hyperplasia effect.
Anti-edema, improve microcirculation, strengthen blood circulation
(Palmitoyl Pentapeptide-3 = Palmitoyl-KTTKS, Nickname Matrixyl)
The first dermatologist brought with the vitamin A and other anti-aging ingredients, advertised directly on the dermis layer, to promote collagen proliferation, to achieve the purpose of tight skin, and other moisturizing ingredients phase, you can accelerate the effect of compact pull The The
Promote collagen and hyaluronic acid hyperplasia, improve skin moisture content, elasticity
Hexapeptides: anti wrinkle
(Acetyl hexapeptide-3 = Ac-EEMQRR-NH2, nickname Argireline)
Also known as botulinum classin, with the inhibition of excessive release of neurotransmitters, affecting the subcutaneous nerve and muscle transfer protein between the role of slowing the face of the crow's feet, the law of the best pattern of stripe, the French dermatologist research, Six peptides used in the eye wrinkles effect is particularly evident.
When the skin by external stimuli or ultraviolet radiation, located in the basal layer of α-melanoma will be combined with melanoma cells on the receptor, directly stimulate the melanoma cells, activation of tyrosine, began to secrete melanin, nine wins Peptides can block at the source of melanin, stop the transmission of alpha-melanin messages, and avoid binding to receptors on melanocytes to reduce melaninogenesis.
Blue Copper Peptide: Revitalizing
Blue copper peptides is the perfect formula for divalent copper ions + tripeptide
Copper peptides, the first is used to treat gastric ulcer oral administration of drugs. Copper is one of the basic elements of the body, in the function of the skin tissue, can help the wound healing. Copper ions can not be alone into the underlying skin, therefore, through the glycine, alginine, histidine, etc., and a copper ion linked to the blue copper peptides, copper can be imported into the skin, the perfect play a refreshing effect. Blue copper peptides can effectively promote the collagen and elastin production and antioxidant capacity, while more in-depth skin penetration, promote self-repair ability, play the ultimate healing wrinkle effect.
