Fructooligosaccharides

Product Description

Fructooligosaccharides (FOS) are plant-derived prebiotic oligosaccharides composed of short-chain fructose units.

They are used in cosmetic formulation systems as functional carbohydrates to support skin conditioning and microbiome-related formulation design.

FOS is applied in modern skincare systems where gentle, water-compatible, and microbiome-oriented ingredient structures are required for formulation development.
