Science
Mechanism of Action
Alpha-Glucan Oligosaccharide operates as a prebiotic, strategically nourishing commensal skin microorganisms, such as *Staphylococcus epidermidis*, while actively discouraging the proliferation of undesirable pathogens like *Staphylococcus aureus*. This selective nurturing rebalances the skin's microbiota, thereby reinforcing the cutaneous barrier against external aggressors and significantly reducing transepidermal water loss (TEWL) to enhance hydration. The ingredient further contributes anti-inflammatory benefits, which can reduce irritation, redness, and flaking. It also stimulates the release of antimicrobial peptides by keratinocytes and supports increased lipid production, collectively strengthening the skin barrier. Moreover, alpha-glucans generally exhibit immunostimulating properties and hold potential for collagen production stimulation.
