Mannose
What is Mannose?
Mannose is a naturally occurring aldohexose sugar, a simple monosaccharide structurally similar to glucose but differing at the C-2 position. It originates from various plants, fruits like cranberries, and algae, where it serves as a component of cell walls and metabolic processes. In cosmetics, mannose functions primarily as a humectant, binding water molecules from the environment and lower skin layers to the outermost stratum corneum. This mechanism supports skin barrier integrity by maintaining optimal moisture levels without relying on occlusive barriers. Commonly incorporated into moisturizers, serums, cleansers, and hair care products at low concentrations, it integrates seamlessly into water-based formulations. Its mild, non-sticky profile makes it suitable for daily use across diverse skin types, enhancing product feel while promoting sustained hydration through osmotic attraction.
