What Is Prebiotic Complex?
Prebiotic complexes contain ingredients that selectively nourish beneficial skin bacteria while discouraging harmful organisms. Common prebiotics include alpha-glucan oligosaccharide and inulin.
A balanced skin microbiome is essential for barrier function, immunity, and overall skin health. Prebiotics support this balance by providing food for good bacteria.
Unlike probiotics (live bacteria), prebiotics are stable and easy to formulate while still supporting microbiome health.
