Peptides are combinations of peptides, small molecules of collagen that are naturally found in the skin.
Cosmetics contract manufacturers have shown that polypeptides are effective in improving fine lines. They are milder than retinol and suitable for all skin types.
Peptides are a large family, so it is common to add a specific number to the end of the peptides’ names to distinguish them.
For example, two amino acids are called dipeptides, three amino acids are called tripeptides, and so on.
A key role of these peptides in skincare is to enable effective communication between skin cells.
When aging skin is unable to produce a rejuvenating state, the signal peptides use the activity of the extracellular matrix to inform aging cells, and at the same time send a “distress signal” to fibroblasts to stimulate the production of more collagen, which keeps our skin plump.
Representative components of this kind of peptides: palmitoyl pentapeptide-3, palmitoyl tripeptide-1, palmitoyl pentapeptide-4, palmitoyl hexapeptide, palmitoyl tripeptide-5 and so on.
Pentapeptide-4 is proved by many experiments to have more anti-wrinkle ability, so many anti-aging products have its figure.
Carrier transport peptide
This kind of peptide is mainly responsible for the transportation work, the metal trace elements needed by the skin, transported to the place where they are needed, to play the anti-aging function of the skin, increase collagen and elastic protein, so as to tighten the skin and fade wrinkles.
Representative components of transport peptides are: blue copper tripeptides.
Nerve neurotransmitter inhibitory peptide
Peptides, which mimic Botox’s anti-wrinkle mechanism, interfere with nerve endings and release acetylcholine to control muscles, helping to improve dynamic wrinkles.
Studies have proved that this kind of peptide can reduce about 30% expression lines, representative components are: acetyl hexapeptide, dipeptide snake toxin, etc.
Retinols, also known as A-alcohols, belong to the large class A family.
Mechanism of anti-wrinkle action When topically applied, retinol breaks down into retinoic acid, inhibiting enzymes that break down collagen, reducing collagen loss, and promoting skin cell renewal and growth, thus reducing the appearance of fine lines.
The anti-wrinkle effect of retinol skin care products is good, the price is close to the people, nearly 100 yuan to two or three hundred have, the vast majority of sisters can bear.
The main retinol anti – aging products are many.
Retinol has 3 big shortcoming, it is excitant big, 2 it is stability is poor, 3 it is photosensitivity.
So just contact retinol products are recommended to test the tolerance of a small area, and it is recommended to use at night, use in the daytime to strictly sunscreen.
But retinol is only sensitive to sunlight, not light, so you don’t have to turn the lights off at night.
