An important component of the skin's barrier function is the skin microbiome. Human skin is populated by a variety of microorganisms, particularly bacteria, which form the so-called skin microbiome. Humans and their skin microbiome form a symbiosis: the skin needs the microbiome and the microbiome needs the skin. Imbalances in the microbiome are reflected in changes to the skin, such as dry or sensitive skin.

One way to strengthen the skin microbiome is to provide it with "good food", so-called prebiotics. The prebiotic used here is an alpha-glucan oligosaccharide that is obtained from plant substrates (two sugars: sucrose and maltose) through enzymatic biocatalysis.

Betaine is a derivative of the amino acid glycine. It has excellent moisture-retaining properties, which is why betaine can support the skin's moisture retention capacity and thus help to improve the skin's hydration._x000B_The name betaine is derived from the Latin word for beet (Beta vulgaris), as betaine occurs naturally in high quantities in beets.

Betaine is naturally found in large quantities in beets. The betaine used here also comes from beets. It is obtained from beet sugar molasses in an upcycling process.
