ASPERGILLUS/SACCHAROMYCES/PRUNUS MUME FRUIT/RICE FERMENT LEES EXTRACT.

Valuable / HAIR CONDITIONING, HUMECTANT, SKIN CONDITIONING

A high-performance bio-fermented complex derived from Japanese Apricot and Sake Kasu (Rice Lees) using a dual-culture fermentation process. It is specifically engineered to target the physiological causes of skin sallowness and structural protein degradation.

Science

Mechanism of Action

This ingredient utilizes a double fermentation system to release a high concentration of bioactive polyphenols and amino acids. It functions as a potent anti-glycation and anti-carbonylation agent, effectively inhibiting the Maillard reaction which leads to the formation of Advanced Glycation End-products (AGEs). By preventing these cross-linked proteins, it protects collagen elasticity and stops the yellowing of the stratum corneum while simultaneously boosting Natural Moisturizing Factors (NMFs).

Key findings

  1. 01 In vivo testing at 1.0% showed a significant reduction in skin yellowness and a 14.2% increase in skin translucency over a 4-week period.
  2. 02 In vitro analysis at 2.0% demonstrated a 45% inhibition of Advanced Glycation End-products (AGEs), highlighting its role in collagen preservation.

Ferment extracts are frequently used at 'claim' levels (0.1% or less) for marketing purposes. However, clinical data suggests that a minimum of 1.0% is required to see measurable improvements in skin translucency and anti-yellowing effects.

Stability

The extract is highly stable in aqueous systems but is thermolabile; it must be incorporated during the cooling phase of production (below 40°C) to protect the integrity of the fermented peptides.

Synergies

  • Vitamin C (antioxidant synergy)
  • Niacinamide (enhanced brightening)
  • Hyaluronic Acid (complementary hydration)

Conflicts

  • Strong oxidizing agents
  • Highly alkaline environments (pH > 8.0)
