Antioxidant Skin Conditioning Skin Protecting Bleaching Hair Conditioning

Science

This ingredient functions as an antioxidant, proactively inhibiting oxygen-promoted reactions that can lead to ingredient degradation and cellular damage. Its skin conditioning and protective benefits are largely attributed to the byproducts generated during Lactobacillus fermentation, which include a complex mixture of intracellular and extracellular metabolites, enzymes, peptides, and organic acids like lactic acid. Research on related Lactobacillus ferments indicates additional mechanisms such as DNA repair, antimicrobial and anti-inflammatory effects, enhanced cellular oxygen uptake, stimulation of collagen production, and ATP synthesis (demonstrated in in-vitro studies). Furthermore, there is a potential for tyrosinase-inhibiting properties, which could influence skin pigmentation.

Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel concluded that related Lactobacillus ferment ingredients, consisting primarily of fermentation byproducts rather than live bacteria, are safe for cosmetic use. The highest reported concentration for Lactobacillus Ferment in face and neck products is up to 5.6%. Formulators are advised that skin lightening is considered a drug effect, and cosmetic applications should not be formulated to induce skin depigmentation. Inhalation toxicity data for spray applications is not currently available.
