LACTOBACILLUS/DATA FRUIT FERMENT FILTRATE.

Valuable / SKIN CONDITIONING

LACTOBACILLUS/DATA FRUIT FERMENT FILTRATE is a postbiotic ingredient derived from the fermentation of fruit by Lactobacillus bacteria. It is engineered to optimize skin's microbiome balance, fortify its natural protective barrier, and deliver comprehensive benefits ranging from hydration and soothing to skin brightening and renewal.

Science

This precision-fermented filtrate enriches the skin with a complex array of beneficial compounds, including amino acids, peptides, organic acids (such as lactic acid), enzymes, and antioxidants. These active metabolites work synergistically to foster a balanced skin microbiome, promoting cell renewal and strengthening the skin's inherent protective mechanisms. It significantly enhances skin hydration by increasing moisture levels and stimulating the endogenous production of ceramides and essential lipid molecules, critical for barrier integrity. Furthermore, it exhibits anti-inflammatory properties, effectively calming irritated skin, and assists in maintaining an optimal skin pH. Certain metabolites have demonstrated the capacity to inhibit tyrosinase, an enzyme involved in melanin synthesis, thereby contributing to skin brightening and the reduction of hyperpigmentation. Its antimicrobial activity helps to create an environment inhospitable to detrimental bacteria and fungi, safeguarding the dermal ecosystem.

Stability

As a water-soluble ferment filtrate, this ingredient is typically stable within an acidic pH range, with optimal activity often observed between pH 3.2 and 5.0. Fermentation processes involving Lactobacillus strains in fruit bases commonly yield stable pH values around 3.8 to 4.0, which can also contribute to product preservation.

Sensitization risk Low

The CIR Expert Panel has deemed Lactobacillus Ferment and related filtrates safe for cosmetic use. Reported usage concentrations for Lactobacillus Ferment extend up to 5.6% in leave-on products. Human Repeat Insult Patch Tests (HRIPTs) have indicated a low potential for irritation and sensitization. However, due to individual sensitivities, a patch test is still recommended for individuals with highly reactive skin.
