Peptides are short chains of between two and fifty amino acids, linked by peptide bonds. Chains of fewer than ten or fifteen amino acids are called oligopeptides and include dipeptides, tripeptides, and tetrapeptides.
The peptide is a kind of small molecular protein, which is found in growth factors extracted from the human body. It is a natural substance combined with a variety of amino acids. The structure of peptides is larger than amino acids and smaller than proteins.
It should be noted that protein cannot be directly absorbed and used by the human body, the individual amino acids and peptide chains separated by the protein can be absorbed by the human body.
Due to the relative molecular mass is small, it is easily absorbed by the skin, which can stimulate the skin’s own collagen proliferation and synthesis, reduce the loss of the collagen, and decrease the facial wrinkles.
At present, peptides are roughly divided into the following categories: Tripeptides are growth factors that have anti-aging and anti-sagging functions. Pentapeptides can promote collagen proliferation and thicken the skin. Hexapeptides are botulinum toxins that relax and reduce wrinkles. Nonapeptides can block melanin promotion and have a whitening effect.
| TYPES OF PEPTIDES | EFFECT |
| Prezatide Copper Acetate | Anti-inflammatory, stimulate the formation of protein and glucosamine |
| Acetyl Hexapeptide-8 | Inhibit muscle contraction, smooth facial lines |
| Acetyl Hexapeptide-3 | Inhibit muscle contraction, smooth facial lines |
| Hexapeptide-2 | Reduce facial melanin deposits |
| Dipeptide-2 | Promote lymphatic circulation and detoxification |
| Carnosine | Anti-oxidation, scavenge free radicals, delay cell aging |
| Palmitoyl Oligopeptide | Increase the synthesis of collagen and hyaluronic acid in the intercellular substance |
| Tripeptide-10 Citrulline | Increase the synthesis of collagen, decrease fine lines |
| Tripeptide-1 | Promote type III collagen proliferation, anti-wrinkle, and firm skin |
| Palmitoyl Tetrapeptide-7 | Remove eye toxins and puffiness |
| Palmitoyl Tetrapeptide-3 | Improve firmness and elasticity, anti-inflammation |
| Pentapeptide-3 | Inhibit muscle contraction, smooth facial lines |
| Palmitoyl Pentapeptide-3 | Promote Type Ⅰ & Type Ⅲ collagen proliferation |
| Nonapeptide-1 | Inhibit tyrosinase, weaken the formation of melanin |
However, due to the wide variety of amino acids, a peptide may have different permutations and combinations, so it will produce different effects. Both peptides and polypeptides are stable and mild ingredients. For pregnant women, choose anti-aging products that contain peptides should avoid retinol ingredients. For sensitive skin, choose peptides that do not contain allergenic ingredients.
This Peptide Protein Repair Eye Cream contains Peptide Compound Essence, Hydrolyzed Pearl, and Wheat Protein, which reduce dullness, fade dark spots, deeply nourish skin, increase skin elasticity, improve skin’s immunity, soften and refine the skin.
It’s nearly impossible to find knowledgeable
people in this particular subject, however, you sound like
you know what you’re talking about!
Thanks
Peptides have become a key research direction of skin care brands. The initial research results have made it the main ingredient in anti-aging skin care products.
