SACCHAROMYCES/RICE FERMENT FILTRATE.

Valuable CAS - / SKIN CONDITIONING

Saccharomyces/Rice Ferment Filtrate is a bio-active postbiotic derived from the meticulous fermentation of rice by yeast. This advanced ingredient offers profound hydration, potent antioxidant defense, and vital nourishment to the skin. It is recognized for its comprehensive benefits, ranging from skin barrier restoration to significant anti-aging support.

Summary

Skin-conditioning Antioxidant Humectant Moisturizing Soothing Skin brightening Wrinkle repair Restoring skin barrier Stimulates cell metabolism Harmonizes skin microflora Repairs damaged cells Enhances skin immunity Reduces redness and irritation Promotes skin renewal

Science

Mechanism of Action

This ferment filtrate functions as a natural antioxidant, actively neutralizing free radicals to protect the skin from premature aging. It deeply hydrates by drawing and locking in moisture, fortifying the skin's natural barrier, and encouraging the release of intrinsic Natural Moisturizing Factors (NMFs). Rich in essential vitamins, minerals, amino acids, polysaccharides, and peptides, it provides comprehensive cellular nourishment. Its soothing properties help to alleviate redness and irritation, making it suitable for sensitive and problematic skin by reducing inflammation. Furthermore, it stimulates collagen production to enhance skin elasticity, reduces the appearance of fine lines and wrinkles, promotes skin renewal, harmonizes the skin's microflora, and may assist in regulating oil production and pore size. The ingredient also supports the repair of damaged cells and bolsters overall skin immunity and resistance.

Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has issued an 'Insufficient Data Announcement' for yeast-derived ingredients, including Saccharomyces Ferment Filtrate, requesting further dermal sensitization and GRAS (Generally Recognized As Safe) status data. However, multiple sources indicate it is generally well-tolerated in cosmetic products with no reported side effects. Safety Data Sheet assessments indicate no potential for dermal irritation, allergic contact, or ocular irritation. It is recommended for use in leave-on products at concentrations ranging from 0.1% to 5%.
