The beauty industry has been doing its best to satisfy women's desire to look older. In recent years, the hot active peptides have been widely used in the cosmetics industry. At present, nearly 50 kinds of raw materials have been launched by famous cosmetics manufacturers abroad. Due to the complexity of aging causes, various kinds of beauty peptides play a unique role in different mechanisms to achieve the purpose of anti-wrinkle. Today, let's take a look at the various peptides and numbers on the ingredient list.
The traditional classification divided aesthetic peptides by mechanism into Signal peptides, Neurotransmitter inhibiting peptides, and Carried peptides.
One. Signal peptides
Signaling peptides promote the synthesis of matrix protein, especially collagen, and may also increase the production of elastin, hyaluronic acid, glycosaminoglycans, and fibronectin. These peptides promote collagen synthesis by increasing stromal cell activity, making skin look more elastic and youthful. Similar to traditional wrinkle fighting ingredients, such as vitamin C, vitamin A derivatives. Studies by P&G have shown that palmitoyl pentapeptide-3 promotes the production of collagen and other extracellular matrix proteins, including elastin and fibronectin. Palmitoyl oligopeptides (palmitoyl tripeptide-1) do much the same thing, which is why palmitoyl oligopeptides are so commonly used. Palmitoyl pentapeptide-3, palmitoyl tripeptide-1, palmitoyl hexapeptide, palmitoyl tripeptide-5, hexapeptide-9 and nutmeg pentapeptide-11, which are commonly sold in the market, are signal peptides.
Two. Neurotransmitter peptides
This peptide is a botoxin-like mechanism. It inhibits SNARE receptor synthesis, inhibits excessive release of skin acetycholine, locally blocks nerve transmission muscle contraction information, and relaxes facial muscles to soothe fine lines. These peptides are as widely used as signal peptides and are particularly suitable for use in areas where expression muscles are concentrated (the corners of the eyes, face, and forehead). Representative peptide products are: acetyl hexapeptide-3, acetyl octapeptide-1, pentapeptide-3, dipeptide ophiotoxin and pentapeptide-3, among which the most widely used is acetyl hexapeptide-3.
Three. Carried peptides
The tripeptides (Gly-L-His-L-Lys(GHK)) in human plasma have a strong affinity with copper ions, which can spontaneously form a complex copper peptide (GHK-Cu). Copper extract is an essential component for wound healing and many enzymatic reaction processes. Studies have shown that GHK-Cu can promote the growth, division and differentiation of nerve cells and immune-related cells, and can effectively promote wound healing and germinal growth. The product represented by copper peptide is copper peptide.
Four. other types of peptides
The general function of traditional peptides is anti-wrinkle and anti-aging except copper peptide (copper peptide has many properties at the same time). In recent years, the variety of peptides has been increasing, some of which achieve the purpose of anti-wrinkle and anti-aging from the brand-new mechanism and perspective (anti-free radical oxidation, anti-carbonylation, anti-inflammatory, anti-edema and promoting dermal repair).
1. Anti-sagging skin, promote skin firming
Palmitoyl dipeptide-5, hexapeptide-8, or hexapeptide-10 tighten skin by stimulating LamininV type IV and VII collagen, while palmitoyl tetrapeptide-7 reduces interleukin-6 production and reduces inflammation. This kind of functional peptide is very active development, new models are constantly increasing, the most used is palm tetrapeptide-7.
2. Glycosylation
These peptides can protect collagen from destruction and crosslinking by reactive carbonyl species (RCS), while some anti-carbonyl peptides can scavenge free radicals. Traditional skin care attaches great importance to anti-free radicals, increasingly apparent anti-carbonylation. Carnosine, tripeptide-1 and dipeptide-4 are the peptides with such functions
3. Improve eye edema, improve microcirculation and strengthen blood circulation
Acetyltetrapeptide-5 and dipeptide-2 are potent ACE inhibitors that improve blood circulation by inhibiting the conversion of angiotensin I to angiotensin II.
4. Promote dermal repair
Palmitoyl hexapeptidde-6, a genetic immune peptide template, can effectively stimulate fibroblast proliferation and linking, collagen synthesis and cell migration.
The above anti - aging peptides have included most of them. In addition to the anti-aging peptides mentioned above, many other cosmetic peptides have been developed in the industry, such as whitening, breast enhancement, weight loss and so on.
