Introduction to the functions and effects of beauty peptides

Introduction to peptides

Cosmetic peptide, translated as beauty peptide or beauty peptide in Chinese, is a small-molecule collagen that is degraded and contains amino acid groups, generally composed of 2-10 amino acids. Peptides are also components that exist in the human body and are a chain structure composed of amino acids. The protein we are familiar with is a multi-peptide chain.

Peptides are composed of amino acids connected by peptide chains, but each peptide can be composed of many different amino acids. Two kinds of amino acids are called dipeptides, three kinds of amino acids are called tripeptides, and so on. The three peptides, five peptides, and even nine peptides that are often heard are all oligopeptides. Each oligopeptide chain has a different effect. Usually peptides with less than 10 amino acids are called oligopeptides, those with more amino acids are called polypeptides, and those with more than 50 amino acids are called proteins. Due to the different varieties of amino acids contained, there are also different varieties of di-peptides and tripeptides, so “peptides” with various functions and various names have appeared.
Peptides are involved in the human body’s hormones, nerves, cell growth and reproduction. Its importance lies in adjusting the physiological functions of various systems and cells in the body, activating related enzymes in the body, promoting the permeability of the intermediate metabolic membrane, or by controlling DNA transcription Or affect specific protein synthesis, and ultimately produce specific physiological effects.

The beauty function of peptides in cosmetics

The biological activity of peptides depends on their amino acid composition and sequence. Almost all physiological processes in the human body are regulated by polypeptides or proteins composed of specific amino acid sequences. Therefore, biologically active peptides have become a new direction and idea for the development and application of cosmetics, and their functions are becoming more and more subdivided, such as: anti-aging, anti-allergic, repairing, anti-oxidation, anti-edema, promoting hair regeneration, inhibiting melanin production, and breast enhancement , Weight loss, etc.

The skin is the human body’s natural barrier against external environmental aggressions, and has a certain protective effect against external stimuli, thanks to the protective effect of the skin’s dense stratum corneum. However, the nutrients of cosmetics are also blocked on the surface of the skin. Nutrients need to penetrate the stratum corneum cell membrane to enter the dermis. Only a small amount of macromolecules and fat-soluble substances can be absorbed through pores and sweat pores. Therefore, most of the cosmetics we usually use only stay on the surface of the skin, while the biologically active beauty peptides can easily pass through the stratum corneum and enter the dermis, thereby playing a role.

Peptides were originally used directly in products by some European and American cosmeceuticals. The mechanism of action is similar to that of protein. It can promote the proliferation of collagen, elastic fiber, polysaccharides and hyaluronic acid, increase skin moisture content, increase skin thickness and reduce fineness. Pattern. Due to the different types of amino acids contained, they can play different roles to meet the needs of different functions of the skin.

Functional classification of peptides:

Instant wrinkle removal
Snake venom three peptides SYN-AKE
The snake venom tripeptide partially blocks the nerve transmission of muscle contraction information, affects the nerve conduction of the cortex, relaxes the facial muscles, and achieves the effect of smoothing dynamic lines, static lines and fine lines.

Acetyl hexapeptide-8

Acetyl hexapeptide-8 is also known as botulinum toxin. It has the effect of inhibiting the excessive release of nerve substances and affecting the transfer protein between subcutaneous nerves and muscles. It has the best effect on slowing down dynamic lines such as crow’s feet and nasolabial lines on the face. According to French dermatologists, the effect of hexapeptide on wrinkles around the eyes is particularly obvious.

Promote the synthesis of protein, polysaccharides and hyaluronic acid, improve skin texture

Tripeptide GHK

Tripeptides are the first to be discovered in the arrangement and combination of peptides. They are regarded as growth factors and can stimulate the production of glucosamine and collagen. It was separated from wound healing tissue in 1990 and has the effect of promoting wound healing and proliferation.

Blue copper peptide is the perfect formula of divalent copper ion + tripeptide
Copper peptide was originally an oral medicine used to treat gastric ulcers. Copper is one of the basic elements of the body. In the function of skin tissue, it can assist in the healing of wounds. Copper ions cannot enter the bottom layer of the skin alone. Therefore, through the blue copper peptide linked with a copper ion, such as glycine, lysine, histidine, etc., copper can be introduced into the skin, and the skin can be perfectly activated. Blue copper peptide can effectively promote the production of collagen and elastin and antioxidant energy, and at the same time penetrate deeper into the skin, promote self-repair ability, and exert the ultimate effect of smoothing wrinkles.

Hexapeptide-9

Hexapeptide-9 promotes collagen production and epidermal differentiation, remarkably anti-wrinkle; powerful repair (especially for the repair of acne marks); fight against sagging skin, making the skin more elastic and firmer.

Palmitoyl pentapeptide-3

Palmitoyl pentapeptide-3 is the first to be used by the dermatology medical community with anti-aging ingredients such as vitamin A. It can directly act on the dermis to promote the proliferation of collagen and polysaccharides to achieve the purpose of firming the skin. It is compatible with other moisturizing ingredients. Zuo, can accelerate the effect of firming and lifting.

Anti-inflammatory reaction, remove red blood streak, reduce allergic discomfort

Acetyl Hexapeptide-49

Acetylhexapeptide-49 reduces the activity of protease-activated receptor 2 (PAR-2), reduces the release of pro-inflammatory response intermediates CGRP, IL6 and IL8, reduces neuroinflammation and alleviates pain, itching and other allergic skin Unwell.

Acetyltetrapeptide-40

Acetyltetrapeptide-40 reduces facial redness and telangiectasia, improves skin tone, and has firming and anti-photoaging effects.

Acetyl dipeptide-13 inhibits elastase activity, enhances the skin’s ability to resist stretching, and maintains elasticity and firmness.

Palmitoyl Tetrapeptide Pal-GQPR
Palmitoyl tetrapeptide-3 is similar to DHEA, regulates inflammatory factors, and restores skin youth and firmness.

Whitening and brightening skin

Jiusheng peptide-1

When the skin is exposed to external stimuli or ultraviolet rays, the alpha-melanotropin located in the basal cells will bind to the receptors on the melanocytes, directly stimulate the melanocytes, activate tyrosine, and begin to secrete melanin, nine peptides It can block and stop the transmission of α-melanin at the source of melanin formation, avoid binding with receptors on melanocytes, and reduce the chance of melanin production.
