About this ingredient
Fucose (INCI: Fucose) is a simple sugar (monosaccharide) that works as a humectant. It draws water into the surface layers and helps keep the skin hydrated. Fucose is also part of some skin glycans, which explains the interest in it for skincare formulas. It is used in serums, creams and masks. On efficacy it is a supporting humectant component. It delivers hydration and a more comfortable feel, but the evidence for more ambitious actions is limited. It works well as part of a moisturizing system rather than as a star active. For topical use it has no systemic relevance and can be used during pregnancy and breastfeeding. Tolerance is good: low irritation potential and low allergy risk, which makes it suitable for sensitive skin. As a humectant, it performs better in formulas that also include an occlusive or emollient to seal the water in.
