About

A probiotic bacterial strain used in skincare to balance skin microbiome and reduce acne-causing bacteria through competitive exclusion.

Cutibacterium acnes (formerly Propionibacterium acnes) CA-81 is a specific non-virulent bacterial strain used as a probiotic cosmetic ingredient to support skin microbiome balance. C. acnes is a normal resident of healthy skin microbiota, and specific strains like CA-81 are selected for their beneficial properties including competitive exclusion of more pathogenic strains. The use of probiotic bacteria in cosmetics is an emerging area with growing scientific support. No specific EU restrictions apply to this ingredient under Regulation 1223/2009, though standard microbiological quality controls for cosmetic products apply to ensure absence of pathogenic organisms.
