About
A probiotic strain of skin bacteria that helps maintain microbiome balance and may reduce inflammation associated with acne-prone skin.
Cutibacterium acnes CA-31 is a specific strain of C. acnes used in probiotic skincare formulations to support skin health through microbiome modulation. Like other non-pathogenic C. acnes strains, CA-31 competes with harmful strains for skin resources and may produce antimicrobial peptides that benefit skin condition. The scientific literature supports the concept of using specific C. acnes strains for skin health, though the field of probiotic cosmetics is still emerging. It is not restricted under EU Regulation 1223/2009, subject to standard microbiological safety requirements for live bacterial ingredients in cosmetics.
