SACCHAROMYCES/RICE BRAN FERMENT FILTRATE EXTRACT.

Valuable / SKIN CONDITIONING

SACCHAROMYCES/RICE BRAN FERMENT FILTRATE EXTRACT is a potent postbiotic ingredient, derived from the fermentation of rice bran with yeast. Rich in antioxidants, amino acids, vitamins, and minerals, it is designed to enhance skin hydration, strengthen the skin barrier, and promote overall skin vitality.

Antioxidant Skin Conditioning Humectant Hydration Booster Anti-aging Skin Brightening Anti-inflammatory Barrier Support

Science

Mechanism of Action

This ferment filtrate provides essential nutrients and potent antioxidants, effectively neutralizing free radicals and offering protection against environmental aggressors such as pollution and UV radiation. It significantly boosts skin hydration by replenishing natural moisturizing factors (NMFs) through its amino acid content, activating aquaporin 3 (AQP3) expression, and stimulating hyaluronic acid synthesis. The ingredient also contributes to restoring skin balance, fortifying the natural barrier, and improving elasticity and firmness by stimulating collagen and elastin production and enhancing fibroblast migration. Additionally, it may contribute to skin brightening by inhibiting melanin, harmonize the skin's microbiome, reduce inflammation, refine skin texture, and minimize the appearance of fine lines and wrinkles.

Key findings

  1. 01 Continuous application of a related fermented product filtrate at 5% for four weeks resulted in a 37.2% average reduction in trans-epidermal water loss (TEWL) and a 62.5% increase in stratum corneum hydration.
  2. 02 A related fermented brown rice filtrate demonstrated significant elevation of hyaluronic acid (HA) levels and enhanced expression of hyaluronan synthase 2 and aquaporin 3 (AQP3) in HaCaT cells, crucial for maintaining skin hydration.
  3. 03 An emulsion containing a related rice fermentation filtrate reduced transepidermal water loss (TEWL) by 25.05% within ten minutes of application in a double-blind, placebo-controlled clinical trial.
  4. 04 Recommended for leave-on products at 0.1%-5% concentration to improve overall skin health, reduce inflammation, promote collagen, improve elasticity, texture, and reduce fine lines and wrinkles.
