About this ingredient
Xylose (INCI Xylose) is a simple plant sugar from the pentose group, obtained from wood and plant material. In skincare it works as a humectant: it draws in water and holds it in the upper skin layers, helping to soften the surface. On efficacy this is a supporting moisturising ingredient. Sugars deliver basic hydration reasonably well, but this is not a strong standalone active, rather part of a formula's moisturising system. Xylose is sometimes claimed as a prebiotic for the skin microbiome, where the evidence base is still modest. Used topically, xylose has no systemic relevance, so it can be used during pregnancy and breastfeeding without restriction. Tolerance is good. The irritation and allergy potential is low, which suits sensitive skin. Sugars are well familiar to the skin and cause no reaction in most people.
