Naturally present in the body, peptides are small transmitters that evolve in our cells to boost the natural process as soon as it slows down.

What are peptides?

Peptides are small chains of amino acids. ” They can be described as small proteins. They include between 3 and 50 amino acids and in cosmetics most often they include between 3 and 10 amino acids. The amino acid being the smallest building block of protein composition”, explains Bethsabée Coutaz, Scientific Director Dr. Pierre Ricaud.

They are naturally present in the skin as cellular messengers and are very easily recognized by cell receptors to reactivate the synthesis of the structural elements of the skin. The most widely used peptides in cosmetics are generally derived from synthesis. The most frequently used synthetic peptides, collagen activators are Matrixyl, or Botox-like peptides such as argireline. Nevertheless, more and more plant peptides are appearing in the cosmetic landscape, such as the lupine peptides present in the Dr. Pierre Ricaud Glow cream, for its ability to strengthen skin microcirculation and improve skin radiance “, develops Bethsabée Coutaz, Scientific Director Dr. Pierre Ricaud.
