LACTOBACILLUS/BARLEY EXTRACT FERMENT EXTRACT LYSATE.

Valuable / SKIN CONDITIONING - MISCELLANEOUS

A postbiotic ingredient derived from the fermentation and lysis of Lactobacillus on barley extract, designed to support the skin's natural microbiome. It delivers beneficial metabolites, cytoplasmic fragments, and cell wall components to enhance skin health, barrier function, and resilience.

Summary

Skin-Conditioning Microbiome Support Barrier Reinforcement Soothing Hydrating Redness Reduction Anti-inflammatory Anti-Acne Anti-Aging Skin Regeneration Improves Skin Tone

Science

Mechanism of Action

This ingredient functions as a postbiotic, contributing to a balanced skin microbiome by providing beneficial compounds. It actively strengthens the skin's protective barrier, diminishing transepidermal water loss (TEWL), which leads to improved hydration and a reduction in redness. By modulating immune responses and stimulating antimicrobial peptide production, it reinforces the skin's natural defense mechanisms. It also promotes skin regeneration, supports cellular renewal, and may increase collagen synthesis, thereby contributing to improved skin tone, reduced inflammation, and a more radiant, youthful appearance. The fermentation process enhances the bioavailability of skin-friendly compounds like amino acids and B vitamins.

Stability

Optimal stability is observed within a pH range of 4-7 and it remains stable at temperatures up to 60 °C. Temporary appearance changes may occur at cold temperatures, which can be reversed by warming to 45-50 °C. The stability of products incorporating lactobacillus fermentation lysis technology with plant extracts can be challenging, particularly concerning oxidative browning of plant polyphenols; decolorization methods used to improve appearance may compromise product efficacy.

Safety

Safety Profile

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

The CIR Expert Panel has deemed related Lactobacillus ferment ingredients, including lysates, safe for use in cosmetics. The maximum reported concentration for Lactobacillus Ferment in face and neck products (non-spray) is up to 5.6%. This ingredient consists of fermentation byproducts rather than live bacteria, exhibiting a low potential for irritation and sensitization. It has been predicted as non-irritating and non-sensitizing in EpiDermTM assays and Human Repeat Insult Patch Tests (HRIPTs). While generally safe, individuals with known sensitivities, particularly to fermented ingredients, may consider patch testing.
