Science
Mechanism of Action
LACTOBACILLUS/HYDROLYZED COLLAGEN FERMENT FILTRATE EXTRACT operates as a robust humectant, effectively drawing and retaining moisture to significantly enhance skin hydration. It actively contributes to strengthening the epidermal barrier, consequently mitigating irritation and supporting a stable, healthy skin microbiome. The fermented component promotes cellular renewal, leading to refined skin texture and a more youthful complexion. Functioning as a natural antioxidant, it neutralizes free radicals, providing essential protection against environmental aggressors and preventing premature signs of aging. The hydrolyzed collagen fraction directly supports the skin's connective tissues, enhancing elasticity and suppleness, and assisting in the amelioration of lines and wrinkles. This ingredient is understood to boost the synthesis of collagen types I, III, and IV, regulate collagen quality, and impede its degradation. Additionally, it supplies beneficial amino acids, peptides, organic acids (such as lactic acid for gentle exfoliation and pH equilibrium), and enzymes, all of which contribute to comprehensive skin repair and recovery. Preliminary data suggests its capacity to inhibit tyrosinase, potentially leading to a reduction in hyperpigmentation and a brighter, more even skin tone.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Panel determined in June 2025 that related ingredients, including Lactobacillus Ferment Filtrate, are safe for use in cosmetics. While this specific extract was not explicitly evaluated, its primary ferment component is covered under this assessment. Use has been reported up to 5.6% in leave-on facial and neck products. A potential for allergic reaction exists for sensitive skin, suggesting a patch test may be prudent.
