Peptides

In general, the peptides act on various targets involved in maintaining skin support and density to limit skin aging, but their role doesn’t end there. Each peptide has its own specific properties, ranging from reducing oxidative stress to hydrating the skin and stimulating cellular renewal.

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

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

Given the wide array of peptides used in cosmetics, it is difficult to make sweeping generalizations. That said, peptides are generally considered safe for all skin types.

It depends on the peptides: some are naturally derived and others have been synthesized in the laboratory. Nonetheless, they are equally 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. Inhibitor peptides, in turn, aim to limit the muscle contractions responsible for expression lines.

No, their mechanisms of action and the intensity of their effects differ. Topical peptides act in a gentle, progressive manner on the surface of the skin. 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 of the skin barrier. Intact proteins, having a higher molecular weight, largely remain on the surface of the skin.
