Science

Mechanism of Action

This fermented ingredient operates through several key pathways: it stabilizes the skin's pH, functions as a natural antioxidant, and stimulates cell renewal to combat premature aging. It enhances skin tone, reinforces the epidermal barrier to optimize moisture retention, and provides soothing anti-inflammatory benefits. By fostering a microflora balance inhospitable to harmful bacteria and stimulating beta-defensins, it supports a healthy microbiome. Furthermore, it produces bioactive compounds like peptides, enzymes, and acids, with in-vitro studies on related ingredients indicating promotion of oxygen uptake, collagen synthesis, and ATP production.

Safety

Safety Profile

CIR Status
Safe as used
Max tested
5.6%
Sensitization risk Moderate

The CIR Expert Panel considers Lactobacillus Ferment and related filtrates safe for cosmetic use, with reported concentrations up to 5.6% in leave-on products. It is generally regarded as non-toxic, non-comedogenic, and non-phototoxic, with no genotoxicity observed in Ames assays. However, a specific risk of allergic reaction for sensitive skin necessitates a patch test. Postbiotics like lactic acid may also exert tyrosinase-inhibiting effects, potentially leading to skin depigmentation.
