Peptides are small chains of amino acids that act as biological messengers within the skin. They can notably stimulate cells to produce collagen and elastin, two essential proteins for maintaining the firmness and elasticity of the skin. There are numerous peptides, each with their own properties. Peptides are now key active ingredients in face and hair care.
Generally, peptides act on various targets involved in supporting and maintaining skin density to limit skin ageing, but their role doesn't stop there. Each peptide has its own properties, ranging from reducing oxidative stress to skin hydration, and stimulating cell renewal.
Can peptides help to reduce wrinkles and fine lines?
Some peptides could help to reduce wrinkles and fine lines by boosting collagen production and promoting the regeneration of skin tissues.
What are the most common peptides in skin care products?
Common peptides include signal peptides such as Palmitoyl Pentapeptide-4 (Matrixyl), inhibitory peptides like Acetyl Hexapeptide-8 (Argireline), and transport peptides such as Copper Tripeptide-1, which stimulate collagen and promote skin regeneration.
Are peptides safe for all skin types?
The peptides are generally safe for all skin types, as they are well tolerated and seldom cause irritations or allergic reactions, even on sensitive skin.
Are the peptides used in cosmetics natural or synthetic?
This depends on the peptides, some are of natural origin and others have been synthesised in a laboratory. Nevertheless, they are equally effective.
