why we use lactobacillus ferment

Microbiome Balancing Postbiotics

While live probiotics typically can't survive in cosmetic formulations (because, well, they're alive), their byproducts—known as postbiotics—can offer significant skin benefits. Lactobacillus Ferment is a postbiotic ingredient produced through the fermentation of Lactobacillus bacteria, yielding beneficial bioactive compounds that support skin health. Lactobacillus Ferment reinforces the skin’s natural microbiome by promoting a balanced microbial environment. As a skin-conditioning agent, it enhances hydration and resilience, helping to maintain a strong skin barrier. Additionally, Lactobacillus fermentation byproducts produce antimicrobial peptides that help defend the skin from external stressors while supporting equilibrium within the skin’s ecosystem. Its soothing properties make it a valuable ingredient in formulations designed for sensitive or reactive skin.1

Antioxidant + Brightening

Beyond microbiome support, Lactobacillus Ferment exhibits antioxidant activity, neutralising free radicals that contribute to oxidative stress. This protection helps maintain skin clarity and overall radiance. Studies indicate that Lactobacillus Ferment can also influence melanin pathways, improving the appearance of uneven skin tone for a more balanced complexion.2
