What is it?

Alpha-Glucan Oligosaccharide — a complex sugar polymer that serves as a selective nutrient source for certain species of beneficial bacteria in the skin microbiome (specifically, representatives of the genus Staphylococcus epidermidis — part of a healthy microbiome), while not supporting the growth of pathogenic or opportunistic pathogenic strains (such as Staphylococcus aureus). Mechanism: unlike general prebiotics that stimulate the growth of all bacteria indiscriminately, alpha-glucan oligosaccharide acts selectively, promoting a shift in the microbiome balance towards beneficial diversity. A healthy, balanced microbiome is closely linked to the strength of the skin barrier and reduced skin reactivity.

Formulations for supporting the skin microbiome, products for sensitive and reactive skin with disrupted microflora balance, barrier-repairing agents of a new generation.

Key Benefits

✦
Selective support of beneficial skin microflora
Alpha-glucan oligosaccharide acts as a selective prebiotic that nourishes beneficial bacteria in the skin microbiome while not supporting the growth of potentially problematic strains. Mechanism: the specific molecular structure of the polysaccharide is primarily absorbed by certain species of beneficial bacteria. Result: support for a healthy, diverse microbiome balance, which is the foundation of a resilient and functional skin barrier.
◈
Support for barrier function through microbiome balance
A balanced skin microbiome is closely linked to the health of the stratum corneum and barrier function — beneficial bacteria produce substances that maintain skin acidity (pH) and compete with pathogens for resources. By supporting this balance, alpha-glucan oligosaccharide indirectly contributes to strengthening the skin barrier and reducing sensitivity.
✧
Modern approach to microbiome-oriented cosmetics
The component represents a new direction in cosmetic science that views the skin not as an isolated organ but as an ecosystem where the balance of microorganisms plays a key role in overall skin health and appearance. Often combined with: prebiotics, probiotics, and postbiotics in complex formulations for the microbiome.
