Alpha-Glucan Oligosaccharide Best Emollient Hydration Soothing Anti-Ageing Alpha-Glucan Oligosaccharide at a glance Natural prebiotic typically synthesized from sugars Helps support a healthy microbiome Can reduce signs of sensitive skin Antioxidant benefits reduce the impact of environmental stressors Alpha-Glucan Oligosaccharide description 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. Related ingredients: Polysaccharide
