Science
Mechanism of Action
This synergistic complex leverages the benefits of Lactobacillus and Saccharomyces ferments alongside fermented Acai fruit extract. It operates by bolstering the skin's natural barrier and microflora balance, fostering an optimal skin pH. Rich in essential nutrients, amino acids, peptides, enzymes, and water-soluble vitamins, it supports cellular repair and renewal. The ingredient provides significant anti-inflammatory and antioxidant protection, neutralizing free radicals and environmental aggressors. Furthermore, it gently exfoliates, enhances hydration, can stimulate collagen production, and contributes to a more even skin tone by addressing hyperpigmentation.

Dusting Analysis
While specific 'dusting' is not indicated, the CIR Expert Panel noted that some Lactobacillus-derived ingredients might exhibit a skin-lightening effect due to tyrosinase inhibition. This is considered a potential 'drug effect' in cosmetics. Formulators are advised to carefully manage concentrations to prevent unintended skin depigmentation, which might lead to lower usage levels depending on formulation goals.

Stability
This ingredient, particularly its Lactobacillus ferment component, is generally stable within a pH range of 4.0 to 5.0. As a fermented postbiotic, maintaining optimal pH control and potentially incorporating co-preservatives are recommended for robust product preservation.
Conflicts
- Requires careful pH control to maintain stability and efficacy.
- May necessitate co-preservatives for a comprehensive preservation system.
- Must be formulated to prevent unintended skin depigmentation, particularly at higher concentrations, due to potential tyrosinase inhibition.
Safety
Safety Profile
The CIR Expert Panel deems Lactobacillus Ferment and its filtrates safe for cosmetic use. Reported usage includes up to 5.6% in face and neck products and up to 1.5% in makeup bases. However, a potential risk of allergic reaction exists for sensitive skin, necessitating a patch test prior to widespread use. Formulators must ensure the ingredient is used in a manner that avoids any unintended skin depigmentation.
