Science
Mechanism of Action
Hydrolyzed Coix Lacryma-Jobi Ma-Yuen Seed works through several biological pathways to optimize skin health. Rich in protective antioxidants like phenols and flavonoids, it effectively neutralizes free radicals and shields the skin from environmental stressors, thus interrupting pro-aging damage. As a humectant, it deeply hydrates, reducing feelings of tightness and plumping skin cells with water. The extract stimulates natural skin renewal and regeneration processes, visibly strengthening the skin barrier and smoothing its surface texture. It also targets melanogenesis to reduce excess pigment, contributing to a more even and radiant skin tone. Furthermore, this ingredient exerts significant anti-inflammatory and soothing effects by inhibiting key mediators such as tryptase, histamine release, and IL-31, which are linked to pruritus and inflammation. It can also suppress epidermal hyperplasia, macrophage infiltration, and the production of pro-inflammatory molecules like IL-1α, PGE2, and COX-2. Additionally, it aids in gentle exfoliation, clearing dead skin cells and impurities, while helping to control acne breakouts and balance sebum production.
