Peptides

In general, peptides act on various targets involved in supporting the skin’s structure and density to limit cutaneous ageing, but their role does not end there. Each peptide has distinct properties, ranging from reducing oxidative stress to enhancing skin hydration, as well as stimulating cellular renewal.

Yes, certain peptides may help to reduce wrinkles and fine lines by stimulating collagen synthesis and promoting the regeneration of skin tissue.

Commonly found peptides in cosmetics include signal peptides such as Palmitoyl Pentapeptide-4 (Matrixyl), inhibitory peptides such as Acetyl Hexapeptide-8 (Argireline), and carrier peptides such as Copper Tripeptide-1, which stimulate collagen production and promote skin regeneration.

Given the multitude of peptides used in cosmetics, it is difficult to generalise. That said, the peptides are generally considered safe for all skin types.

It depends on the peptides; some are naturally derived and others have been synthesised in the laboratory. They are nevertheless just as effective.

The peptides signal peptides stimulate the synthesis of skin components, such as collagen. Carrier peptides facilitate the delivery of essential elements, such as copper. Inhibitory peptides, in turn, aim to limit the muscle contractions responsible for expression lines.

No – their mechanism and intensity of action are different. Topical peptides work in a gentle, gradual manner on the skin’s surface. They do not produce effects equivalent to medical procedures.

Some peptides indeed exhibit hydrating properties, such as SH-Oligopeptide-2 or SH-Polypeptide-1.

Peptides are much smaller than full proteins. This reduced size facilitates their penetration through the skin barrier. Intact proteins, by virtue of their higher molecular weight, predominantly remain on the skin’s surface.
