Coix Lacryma-Jobi Ma-Yuen Seed Extract description

Coix lacryma-jobi ma-yuen seed extract is a skin care ingredient and plant extract derived from the Coix lacryma-jobi ma-yuen plant, a grain-producing grass also known as adlay or Job’s tears. This seed extract possesses antioxidant properties due to phenols and flavonoids present in the seed’s chemical profile. These antioxidant-rich compounds help protect skin, interrupting the cascade of pro-aging damage that external factors can trigger. Research also supports claims that Coix lacryma-jobi ma-yuen can function as a skin-brightening ingredient. It accomplishes this benefit through helping to curb excess pigment that would then go on to form visible dark spots and discolorations. We’ve also seen claims that this seed extract might have calming and hydrating properties, but more research needs to be completed to establish this as fact. Last, optimal usage levels for this ingredient have not been firmly established for use in cosmetics. It’s often part of a blend with other natural ingredients and ferments.
