Valuable CAS - / ANTIOXIDANT, SKIN CONDITIONING, SKIN PROTECTING

Saccharomyces/Rice Ferment Filtrate Extract is a multi-functional fermented ingredient, derived from rice through a controlled yeast fermentation process. It delivers deep, sustained hydration by enhancing key skin components and acts as a potent antioxidant, safeguarding the skin from environmental stressors. This extract further brightens and evens skin tone, soothes irritation, and fortifies the skin's natural barrier.

Science

This fermented rice filtrate functions as a robust antioxidant, shielding the skin from oxidative stress and environmental damage by combating free radicals. It provides profound hydration by stimulating cellular regeneration, enhancing the expression of hyaluronic acid (HA) and aquaporin 3 (AQP3), and fortifying the skin's natural protective barrier to minimize moisture loss. The fermentation process yields a wealth of beneficial, small-molecular-weight substances, including polysaccharides, peptides, amino acids, vitamins, and minerals, which are readily absorbed to nourish skin cells. It possesses soothing and anti-inflammatory properties that reduce redness and irritation, simultaneously promoting a harmonious skin microflora. Furthermore, it stimulates collagen production, improving skin elasticity and reducing the appearance of fine lines, while enhancing overall skin texture, boosting radiance, and evening tone by inhibiting melanin synthesis and encouraging natural exfoliation. For oily and acne-prone skin, it assists in regulating sebum production and minimizing pore visibility.

Sensitization risk Low

Generally regarded as safe for cosmetic use, with no widespread reported side effects. Recommended concentrations range from 0.1% to 5% in leave-on formulations, extending up to 10% for rinse-off products. While largely well-tolerated, a patch test is advisable for individuals with sensitive skin, as some may experience sensitivities or potential breakouts to fermented ingredients, potentially due to increased absorption of smaller molecular byproducts. The CIR has broadly deemed related yeast-derived ingredients safe, even at higher cosmetic concentrations.
