Cosmetics with peptides: how proteins act on the skin

Proteins, proteins or peptides – these are the names of the same high-molecular organic substances that are an important component of the human body. Proteins are everywhere: hemoglobin – it is a protein of erythrocytes, actin and myosin – muscle tissue proteins, keratin and collagen – fibrillar proteins, which are the basis of connective tissue, and so on. Every day, with food of predominantly animal origin, a person consumes the protein necessary for his body. Proteins are also used in cosmetics for external use. How protein affects the skin, and what effects of using cosmetics with peptides should be expected – read on estet-portal.com.

The main effects of using cosmetics with peptides

Cosmetics with peptides is really widely used in modern cosmetology. Such products use different proteins, which, depending on their amino acid composition and molecular weight, will act differently on the skin when it comes into contact with it. The main effects of protein cosmetics are lifting, conditioning, cleansing and moisturizing the skin.

In addition to improving the appearance of the skin, cosmetics with peptides also help to maintain its functional and metabolic activity at the required level.

The positive effects that protein has on the skin make manufacturers of such cosmetics actively expand its selection.

Lifting and conditioning – important effects of cosmetics with peptides

Lifting and conditioning – these are some of the most important effects that cosmetics with peptides have on the skin. They are carried out in this way:

lifting effect: most protein compounds are highly hygroscopic, that is, they have the ability to bind and retain moisture in the skin. Once on the surface of the skin, proteins create a moist film that smoothes the skin texture and makes wrinkles less pronounced. The lifting effect of a protein depends on its molecular weight: the higher it is, the more pronounced the effect;
The effect of conditioning is to soften the skin for a long time due to the formation of a moist protein film. After applying cosmetics with peptides, the feeling of tightened skin disappears, it becomes silky and smooth to the touch.

Cosmetics with peptides have a moisturizing effect on the skin

Moisture – it is a necessary stage of skin care, regardless of its type or age of the person. Cosmetics with peptides have a pronounced moisturizing effect on the skin. High-molecular peptides moisturize the skin due to the formation of the same hygroscopic film on its surface, which acts as a wet compress and retains moisture in the skin layers. Unlike the fatty film, the protein film does not clog pores and does not interfere with gas exchange. The hygroscopic film increases the level of moisture at the surface of the skin, reducing the partial pressure of water vapor and reducing the rate of evaporation of water from the skin. But it is important to take into account the fact that the moisturizing effect of cosmetics with peptides lasts as long as the protein film remains on the surface of the skin.

How does the cleansing effect of cosmetics with peptides work

The effect of cleansing on the skin is produced by enzymes contained in cosmetics with peptides. Once on the surface of the skin, proteolytic enzymes weaken the cohesion of corneocytes by destroying the chemical structural bonds of the desmosomes, facilitating the exfoliation of epidermal cells. Cosmetics with peptides are not focused on the promotion of enzymes deep into the skin, but only focuses on maintaining their activity. For the purpose of cleansing, enzyme peels and cleansing exfoliants are used. The latter remove protein and fatty impurities from the surface of the skin, while peels have a more pronounced exfoliating effect.
