Science
Mechanism of Action
During fermentation, Lactobacillus Ferment Filtrate produces a synergistic blend of amino acids, peptides, organic acids (like lactic acid), enzymes, and antioxidants. These compounds rebalance the skin's natural microbiome, stimulate ceramide and lipid production to strengthen the skin barrier, and enhance cellular renewal. It acts as a natural antioxidant, neutralizing free radicals and offering protection against environmental stressors, while contributing to pH balance, reduced irritation, and potential melanin regulation for brighter skin.

The Formula
Formulation
Stability
Considered 100% soluble and stable in testing, generally offering more stability than live probiotics. Store at room temperature not exceeding 25°C, in a tightly closed container.
Safety
Safety Profile
The CIR Expert Panel concludes Lactobacillus Ferment Filtrate is safe for cosmetic use within present practices and concentrations, up to 5.6%. While predicted non-irritating in undiluted EpiDermTM assays and found non-sensitizing in 100% HRIPTs, its potential to inhibit tyrosinase activity for skin brightening is considered a drug effect; formulators must ensure usage does not induce skin depigmentation. A precautionary patch test is advised for sensitive skin due to a noted, low risk of allergic reaction.
