Summary

Antioxidant Skin Conditioning Skin Protecting Barrier Strengthening Soothing Hydrating Collagen Boosting Texture Improving Skin Brightening Cell Renewal

Science

Mechanism of Action

The co-fermentation of silkworm extract by Lactobacillus and Saccharomyces yields a filtrate abundant in amino acids, peptides, organic acids, and enzymes. Lactobacillus ferment filtrates fortify the skin's barrier function, soothe irritation, and promote a balanced microbiome. They contribute hydration through humectant properties and protect against environmental damage with antioxidant activity. Saccharomyces ferment filtrates complement these actions by supplying vital nutrients and antioxidants, reducing inflammation, stimulating collagen synthesis, and refining skin texture to diminish the appearance of fine lines. This synergistic action supports skin regeneration, softening, and brightening.
