Our take
Is Coix Lacryma-Jobi Ma-Yuen Seed Extract a Good Ingredient?
Traditional use and some preliminary data suggest soothing and antioxidant support, but strong clinical evidence for brightening in leave-on products is limited and extract composition can vary. As a botanical, it carries a small risk of irritation or allergy in sensitive skin. Those gaps in the evidence, plus the added risk, are why it sits at Fair.
