Peptides – small protein molecules composed of amino acids – are very popular today, although there are still scientific debates about their effectiveness in cosmetology and the ability to regulate biochemical processes in the cell.
Cosmetics with peptides are experiencing a real boom in popularity, because they are credited with the miraculous effect of rejuvenation. You can also easily Buy European Peptides online.
All possibilities of peptides have not yet been studied.
Peptides are small molecules composed of amino acids and easily penetrating the skin. If the molecules are larger, this is already a protein. They are able to give commands to the body, and he performs them, because they are peculiar messengers that cells recognize with their receptors. Peptides, like postmen, transmit information and organize proteins. However, many peptides in our body are produced naturally. The best known and most studied peptide today is collagen. The human body consists of proteins (large peptides): hair, skin, female and male hormones, growth hormones. Keratin in the skin is a protein. Collagen and elastin in the dermis of the skin – also proteins. They are included in the processes of division, protection and cell growth.
Previously, peptides were obtained exclusively from food. The process is as follows: when meat enters the digestive tract, it is split into proteins. They in turn are broken down into peptides, which break down into amino acids. Today, peptides are produced synthetically, so they can be used both in creams and in injections. However, they are still in the process of research, although a peptide called tetrapeptide has been known since 1973. Conducted many toxicological studies confirming its safety. The first studies of peptides were aimed at the medical treatment of skin problems, when it was established that with the help of peptides, skin healing can be stimulated. But if the large proteins have long been known, the study of smaller ones continues today.
What problems solve peptides
With age, the amount of protein and collagen in the skin decreases, in addition, skin aging – 80-90% question of external aggression, and not genetic inheritance – this is proved by observations of identical twins, leading different lifestyles (healthy and not). When using peptides in cosmetics, renewal and rejuvenation of the skin can be achieved. In cosmetology today used up to 50 types of peptides, which are already well studied. In addition to the ability to start the renewal process in the skin cells, to increase the production of fibroblasts, peptides solve the problem of skin hypersensitivity and the appearance of redness.
A substance called melanin is a natural and best protection as a UV filter. At the same time, ultraviolet is a small amount of sunlight. Some peptides can increase or suppress the production of melanin, therefore, are used in tanning agents.
There are peptides that are used in anti-aging cosmetics, and those that help the body burn fat. For example, if in one of the most well-known peptides of GHK to swap links, it will contribute to weight loss.
It is believed that the peptide and retinol are incompatible, but this is a myth. Means with retinol and peptides can be used, but separately (in the morning one means with peptides and in the evening – another with retinol).
It is a known fact that when peptides are used separately, the result is not as pronounced as when used together. At the same time, there is practically no difference between the peptides, which are injected and applied using a cream. The difference is only in the time of action, because injection techniques work very quickly and you cannot inject injections often. This was shown by studies of wrinkles (depth, width and other indicators), during which scientists compared the effect of peptide injections and the daily use of creams and serums.
