The cosmetic industry is constantly in search of new active ingredients rich in benefits for the skin and hair. Polysaccharides have been used for some time for their beneficial properties in the formulation of numerous skin care products. Among them, "biosaccharide gum-4", a sugar that would have interesting effects on the skin. Learn more about this active ingredient in this article.

"Biosaccharide gum-4": What is it?
"Biosaccharide gum-4" is an active ingredient that is beginning to be frequently used in the formulation of cosmetic products. This biosaccharide belongs to the family of polysaccharides, which are carbohydrates formed by the condensation of several simple sugars. There are different types of polysaccharides, named according to their various groupings. Polysaccharides generally come from plant sources, but they can also be developed from animal or bacterial sources.
"Biosaccharide gum-4" is more precisely a deacetylated branched polymer derived from sorbitol, a natural sugar alcohol extracted from a plant source. It is produced using a patented biotechnological process. This biosaccharide consists of an L-fucose, two D-glucose, and repetitive units of glucuronic acid. It is a high molecular weight anionic polysaccharide.

"Biosaccharide gum-4": What is its effect on the skin?
Polysaccharides are widely known in the food industry. In cosmetics, they are found in the formulations of many skin products such as creams, serums, or even balms. They help create a biofilm on the surface to protect the skin against dehydration and thus maintain the skin's hydration level throughout the day.
"Biosaccharide gum-4" thus exhibits a beneficial effect on the hydration of the upper layers of the epidermis. This compound demonstrates good stability in formulation, whether in terms of pH or temperature. It allows for the creation of a 3D matrix on the skin's surface in the form of an "occlusive" film, contributing to the maintenance of skin firmness. This film acts as a physical protective shield on the skin's surface. By creating this hydrating barrier, "biosaccharide gum-4" ensures good skin hydration by reducing water loss through the epidermis.
Furthermore, this film-forming effect enhances the penetration of other active ingredients present in the formula. The moisturizing properties of "biosaccharide gum-4" provide the skin with a sensation of softness and protection against external aggressions. This way, the skin is better protected against environmental pollution.
Despite the various noted beneficial effects of "biosaccharide gum-4" in terms of hydration and protection, studies on its mechanism of action remain relatively limited at this time. Additional investigations would be necessary to clarify the different mechanisms involved in the action of the biosaccharide.
