It offers humectant benefits when applied topically. Its humectant abilities mean it assists skin in the retention and attraction of water to skin’s surface. This hydration allows skin to maintain balance, giving it a plump, dewy appearance. Humectants like mannose are commonly included in leave-on products like moisturizers, serums and eye creams. Mannose is naturally occurring in the human body and an integral aspect of the human metabolism process. Beyond this, mannose is regularly used in the food, health and medical industries.
