Probio-Protect™ (Lactobacillus Ferment Preservative) and Skin Microbiota

Probio-Protect™ is a preservative derived from the fermentation of Lactobacillus bacteria. It works by producing peptides called bacteriocins, which have antibacterial properties.

The primary function of Probio-Protect™ is to control the growth of harmful microorganisms in cosmetic formulations, thereby preserving the product. The product description lists its effectiveness (MIC values) against common pathogens like E. Coli, P. Aeruginosa, S. Aureus, A. Brasiliensis, and C. Albicans.

While it is referred to as a "pro-biotic preservative" and originates from beneficial bacteria (Lactobacillus), its mechanism involving bacteriocins is generally more targeted than broad-spectrum chemical preservatives. This suggests it is designed to be less disruptive to the skin's natural microbial balance compared to traditional preservatives.

However, the provided description does not explicitly state whether it completely spares all types of beneficial skin bacteria. Its action is focused on inhibiting the growth of undesirable microbes to maintain product integrity.

In summary, Probio-Protect™ primarily targets harmful bacteria through bacteriocins derived from Lactobacillus fermentation, aligning with its nature as a pro-biotic preservative intended to be less harsh on the skin's microbiome than conventional options.
