BACILLUS/CORN SEED FERMENT FILTRATE.

Valuable / SKIN CONDITIONING

A cutting-edge biotech ingredient derived from the microbial fermentation of Zea mays, designed to deliver high-performance hydration and barrier restoration. It serves as a biomimetic skin-smoother that bridges the gap between deep cellular moisturization and surface-level protection.

Humectant Skin Conditioning Barrier Protection Smoothing Anti-Pollution

Science

Through the fermentation process, Bacillus bacteria break down corn proteins and carbohydrates into a nutrient-dense cocktail of bioavailable peptides and amino acids. These act as powerful humectants that anchor moisture to the skin's surface, while simultaneously forming a breathable, silk-like film that shields against environmental stressors and prevents trans-epidermal water loss (TEWL).
