What Is Alpha-Glucan Oligosaccharide?
Alpha-glucan oligosaccharide is a natural prebiotic that helps support a healthy microbiome. When skin’s microbiome (it’s invisible barrier) is disrupted, the population of harmful bacteria can grow since it’s not being kept in check by healthy flora on the surface. This has the potential to trigger signs of irritation and sensitized skin.
Alpha and beta-glucan oligosaccharides also have antioxidant benefit, helping to reduce the visible effects of oxidative stress on skin.
Recommended usage levels of alpha-glucan oligosaccharide in skin care range from 0.25–3% on its own and 0.5–3% when part of a blend with other prebiotics.
