What is carnosine and how does it protect our skin?

What is carnosine?

When it comes to carnosine research, it goes back 120 years to Russia. The scientists found a small molecule in the mixture extracted from beef. Specifically, it is a "dipeptide" composed of two basic amino acids, alanine and histidine.

Carnosine is a dipeptide composed of alanine and histidine, which is mainly found in animal muscles and is a natural component of muscle tissue. At present, it is widely used in food, medicine and cosmetics industry. Carnosine has obvious inhibitory effect on lipid oxidation caused by free radicals and metal ions, can promote wound healing, and is a good antioxidant.

Simply put, "carnosine" is "a combination of amino acids." This is probably the smallest structure outside of a single amino acid. In many ingredients, Carnosine appears as the English name carnosine.

What does carnosine do for our pale skin?

1. Delay aging

Carnosine can stimulate the production of laminin, and laminin 5 is an indispensable part of the basement membrane. Therefore, it can promote the recovery of barrier function.

Carnosine as a biological substance exists in very high concentrations in muscle and other tissues; By inhibiting protein denaturation, prevent cells from being damaged by environmental pressure, so as to achieve anti-wrinkle firming effect. Carnosine has the effect of repairing the basement membrane, stimulating the production of collagen, and realizing the effect of preventing aging in the dermis.

2, anti-saccharification

Collagen has many glycosylation recognition sites to which free sugar molecules can bind. This causes changes in collagen, and the altered protein also affects the effect of other normal proteins.

And carnosine acts as a pretender, disguising itself as a glycosylation site for collagen; Instead of proteins, glycosylation reactions occur with sugars to prevent collagen glycosylation crosslinking.

Therefore, carnosine can also remove yellow and whiten, lighten skin tone, and repair skin elasticity. The elimination of glycosylated end products, due to its antioxidant effect, can also organize the glycosylation reaction to a large extent. To prevent the cross-linking of macromolecules, thereby protecting the biological function of cells.

3, antioxidant

Carnosine can trap free oxygen radicals, which is particularly effective in preventing the oxidation of protein components (accelerating the formation of wrinkles and the loss of collagen), preventing reactive oxygen species (accelerating the aging of the skin and the formation of melanin), and thus preventing oxidative damage to the skin.

4. Anti-blue light

Carnosine can inhibit pigmentation caused by visible light. Blue light penetrates the skin more than ultraviolet light and can penetrate the surface and dermis of the skin. It causes serious damage to mitochondria in epithelial cells.

During the continuous proliferation of aerobic free radicals, a large number of matrix metalloproteinases are released. It is the culprit of the loss of collagen in the human body and the root cause of skin aging and wrinkles.
