ASPERGILLUS/PICHIA/SORGHUM BICOLOR FERMENT LEES EXTRACT.

Valuable / ANTIOXIDANT, SKIN CONDITIONING

A sophisticated dual-fermented botanical active derived from the nutrient-dense residue of Sorghum bicolor. This bio-active extract leverages a specialized fermentation process to deliver a concentrated shield against environmental stressors while deeply conditioning the skin's natural barrier.

Summary

Antioxidant Skin Conditioning Anti-Pollution Brightening Barrier Repair

Science

Mechanism of Action

This ingredient is created through a synergistic fermentation using Aspergillus and Pichia, which biotransforms complex sorghum proteins and polyphenols into low-molecular-weight, highly bioavailable compounds. These include 3-deoxyanthocyanidins and hydroxycinnamic acids that neutralize reactive oxygen species (ROS) and inhibit tyrosinase for a brightening effect, while the fermented 'lees' provide a rich matrix of beta-glucans and amino acids to reinforce hydration and soothe the epidermal layer.
