Science
Mechanism of Action
The ingredient operates through several synergistic pathways. Its fermented nature generates bioactive compounds, including natural amino acids and peptides, which support a balanced skin microbiome and fortify the skin barrier. These compounds contribute to powerful moisturizing effects, aiding the skin in moisture retention, while accelerating cell renewal and boosting cellular energy levels to support regeneration and repair. Furthermore, its antioxidant capacity protects against environmental damage, its anti-inflammatory properties soothe irritation, and its influence on collagen and hyaluronic acid synthesis helps improve elasticity and reduce the appearance of wrinkles, alongside a noted ability to inhibit melanogenesis for skin brightening.

Key findings
- 01 Components of the ferment filtrate, particularly from Coix Lacryma-Jobi Ma-Yuen Seed, exhibit powerful moisturizing properties, promote skin cell regeneration, reduce inflammation, mitigate signs of aging such as wrinkles, and possess significant antioxidant benefits.
- 02 Fermented Coix lachryma-jobi L. seed fermentation broth significantly increases cell viability, total antioxidant capacity, superoxide dismutase (SOD) activity, catalase (CAT) activity, collagen type I (COL-I) content, and hyaluronic acid (HA) synthesis in human skin fibroblasts, while decreasing reactive oxygen species (ROS) and matrix metalloproteinase-1 (MMP-1), thereby protecting skin structure.
- 03 Coix seed extract prevents inflammation-mediated skin dryness by attenuating reductions in epidermal water content, reducing erythema and scaling, suppressing epidermal hyperplasia, macrophage infiltration, and inhibiting pro-inflammatory mediators (IL-1α, PGE2) and COX-2 upregulation.
- 04 Coix lacryma-jobi seeds demonstrate melanogenesis inhibitory activity, indicating potential as a skin brightening agent.
