Alpha Glucan Oligosaccharide

What is Alpha Glucan Oligosaccharide?

Alpha Glucan Oligosaccharide is a biofermentation-derived oligosaccharide, composed of short glucose chains produced enzymatically from plant-based carbohydrates like corn sugar. It falls under skin conditioning agents in cosmetic formulations. This ingredient functions primarily as a prebiotic, selectively feeding beneficial skin bacteria to promote a healthy microbiome ecosystem. Its humectant qualities draw moisture to the skin, aiding in maintaining suppleness and barrier integrity. Typically incorporated into moisturizers, serums, cleansers, and protective creams at low levels, it enhances product stability and sensory feel without compromising gentleness. Derived through non-GMO processes, it mimics natural skin sugars, integrating seamlessly into daily skincare routines for conditioning effects.
