Peptides are organic compounds,Which are a chain of amino acid residues. A certain sequence of such residues characterizes a particular type of peptides and their action in the human body.
For example, the so-called peptide hormones and neuropeptides, are involved in the process of cell regeneration, "immune" peptides protect the body from toxins.
A number of peptide complexes are used in cosmetology to create anti-aging formulas.
The quality of collagen deteriorates with age - asAny physical body, he suffers from external influences: ultraviolet, free radicals, malfunctions in the body, as well as natural wear and tear of "building material". As a result, the framework of connective tissue, which is built of collagen, loses its elasticity and elasticity.
Skin cells - fibroblasts - synthesizeCertain types of collagen, consisting of special amino acids and protein that cement them, which in essence "guarantees" qualitative collagen. If its synthesis is violated, it is impossible to introduce the protein from the outside - its molecules are too large. But it is possible to introduce short fragments of proteins, peptides, by means of enhancer substances (conductors). Various combinations of amino acid residues trigger certain mechanisms in the skin, in particular those associated with cell regeneration.
Thus, the tetrapeptide decyrylin returnsHomogeneity of the structure of collagen and stimulates its production. Collagen synthesis increases Matrixyl - palmitoyl pentapeptide. The sequence of amino acids in it signals the body that the epidermal protein does not produce enough. Argireline (acetyl hexapeptide) and SYN®-AKE complex (synthetic analogue of snake venom) act as muscle relaxants - they block the transmission of a nerve impulse to the facial muscles, which eventually remain relaxed and do not contract. Thus, it is possible to correct facial wrinkles.
A good anti-aging agent should containA sufficient percentage of peptides - a minimum of 5-6% for basic daily care and 10% or higher for intensive renewal. When choosing a cream with peptides, you need to choose a means in which the peptides are as close to the beginning of the list of ingredients - usually immediately after the emulsifiers (which should not be much). If peptides are in front of preservatives, it is better not to take a useless product - active substances in it will literally be a fraction of a percent.
