Peptides in cosmetology

In the biochemical aspect, peptides are biologically active molecules of natural or synthetic origin consisting of several components of amino acid residues which are joined together by amide bonds.

The sequence of the amino acid residues connection in the chain serves as a specific factor that triggers certain physiological responses in the body.

Peptides are divided into two major groups: regulatory, many of which are hormones, and signaling. It is the signal peptides with two or three amino acid residues that are a basis of beauty products. They belong to the so-called dermal reductants – drugs containing biologically active components having the ability to deeply penetrate into the dermis, affect cell receptors and, as a result, initiate the whole set of biochemical reactions regenerating intercellular substance. In addition, they regulate the metabolic processes in tissues and generation of cellular proteins, normalize lipid oxidation in the skin cells and have antioxidant effect.

Dermal peptides carry out the following processes:

  • Block the melanin synthesis or stimulate its disintegration;
  • Restore the structure of collagen fibers;
  • Suppress the sebaceous gland function and eliminate or reduce the creation of acne;
  • Increase metabolism;
  • Regenerate the walls and stimulate the growth of the small blood vessels, regulate their permeability, etc.
