Science
Mechanism of Action
This ingredient operates primarily as a humectant, drawing water into the stratum corneum and enhancing skin hydration. The smaller xylooligosaccharide (XOS) fragments, resulting from hydrolysis, are hypothesized to exhibit prebiotic effects, fostering a healthy skin microbiome. Furthermore, these fragments may offer immunological and antimicrobial support, thereby reinforcing the skin's protective barrier and contributing to a soothed complexion, as indicated by observations in xylan-based hydrogels demonstrating cytocompatibility and anti-microbial activity.
