ASPERGILLUS/SORGHUM BICOLOR FERMENT LEES EXTRACT.

Valuable / ANTIOXIDANT, HAIR CONDITIONING, SKIN CONDITIONING

A sophisticated upcycled bioactive produced by fermenting sorghum grains with Aspergillus fungi. This nutrient-dense extract serves as a precision tool for simultaneous skin brightening and architectural reinforcement, delivering a high-potency blend of peptides and vitamins.

Antioxidant Skin conditioning Collagen protection Tyrosinase inhibitor Barrier repair

Science

This ferment functions through a dual-action pathway: it inhibits tyrosinase enzymes to disrupt melanin production while simultaneously suppressing MMP-1 enzymes that degrade collagen. It further supports the skin's structural integrity by stimulating fibroblast activity and providing a complex of antioxidant polyphenols and B-vitamins to fortify the epidermal barrier.

Key findings

  1. 01 In vivo trials demonstrated a significant reduction in transdermal water loss (TEWL) and measurable increases in epidermal moisture content.
  2. 02 SGS-verified testing confirmed the inhibition of melanin synthesis and tyrosinase activity in human live skin models.
  3. 03 Patent data indicates that concentrations as low as 0.05% begin promoting fibroblast proliferation and inhibiting collagenase gene expression.
