Cosmetic Peptides

Introduction to Peptides

Peptides are a class of compounds formed from α-amino acids linked together by peptide bonds, and are also intermediates of proteolysis. According to the number of amino acid molecules in the compound, it can be divided into different substances. Compounds where two amino acid molecules are linked by peptide bonds are called dipeptides, compounds where three amino acids are linked by peptide bonds are called tripeptides, and so on. Usually, peptides consisting of less than 10 amino acids are called oligopeptides, and those consisting of 10 to 50 amino acids are called polypeptides. Polypeptides with more than 50 amino acids are known as proteins. Oligopeptides have more medicinal and commercial utility. Each peptide can be composed of many different amino acids. As a result, peptides with various roles and various names have emerged.

Peptides are involved in various fields such as hormones, nerves, cell growth and reproduction in the human body. They can adjust the physiological functions of various systems and cells in the body, activate related enzymes, and promote the permeability of intermediate metabolic membranes. By controlling DNA transcription or affecting specific protein synthesis, peptides ultimately produce corresponding physiological effects and complete body regulation. Many active substances in the human body exist in the form of peptides, which are indispensable and important substances for the human body.

The fields of application of peptides are broad.

1. In the field of medicine: Compared with chemical small-molecule drugs, peptide drugs have stronger biological activity, smaller dosage, lower toxic and side effects, and significant curative effect, so they have attracted the attention and favor of new drug developers. At present, more than 1,000 peptide drugs have been marketed in the world.
2. In the field of food: there are many kinds of peptides, rich sources, high safety, diverse physiological functions, and high bioavailability, which can quickly supply energy to the body, promote lipid metabolism and restore physical strength, and can be used to prepare food.
3. In the field of cosmetics: There are hundreds of cosmetic peptides all over the world with significant cosmetic effects.

Beauty Effects of Peptides in Cosmetics

The biological activity of peptides depends on their amino acid composition and sequence. Almost all physiological processes in living organisms in nature are regulated by peptides or proteins composed of specific amino acid sequences. Therefore, peptides are widely used in cosmetics, providing a new direction and idea for the research and development and application of cosmetics.

Cosmetic peptides generally have the following characteristics at the same time:

1. Specific amino acid sequence and molecular weight structure. Common cosmetic peptides are formed by the condensation of 2-10 amino acids, and the molecular weight is about 1000 Daltons.
2. The mechanism is clear, and it clearly acts on a microscopic level of the skin.
3. The purification effect is concentrated and the content is high.

The main beauty effects of peptides used in cosmetics are:

1. Promote cell metabolism: Peptides can promote and maintain the normal metabolism of cells, thereby promoting the regeneration of skin cells.
2. Activating the activity of cells: By activating the activity of cells, peptides can effectively remove free radicals that are harmful to the human body, reduce the accumulation of stains, make the skin fair and translucent, and delay aging.
3. Inhibit cell degeneration: Peptide can effectively inhibit cell degeneration and enhance human immunity, thereby reducing the loss of collagen and enhancing the ability of skin cells to retain moisture.
4. Repair damaged cells: Peptides can repair damaged cells, thereby reducing skin oxidation.
5. Promote collagen synthesis: Peptides are organic substances that constitute various types of connective tissue and can help collagen synthesis rapidly.
6. Promote cell healing: Peptides can affect the migration and proliferation of epidermal cells, promote the growth of skin and nerves, and facilitate the proliferation and repair of cells, thereby promoting the healing of wound surfaces.
