Probiotics & Prebiotics
Fermented lysates, postbiotic ferments, and prebiotic sugars support the skin's microbiome — the ecosystem of bacteria that helps maintain barrier health. K-beauty pioneered this category with galactomyces and bifida ferments; Western brands followed with lactobacillus and saccharomyces derivatives.

Evidence level
Promising. Growing evidence for barrier support and reduced sensitivity in reactive skin. Individual ferments have varying evidence — galactomyces (SK-II Pitera) and bifida ferment lysate have the strongest data. The microbiome skincare category is young; expect significant research expansion.
