About this ingredient
Job's tears seed extract (INCI Coix Lacryma-Jobi Ma-yuen Seed Extract) comes from an Asian grain crop. It supplies proteins, starches and amino acids, and in cosmetics it works as a hydrating, conditioning agent that leaves skin soft. A caveat on efficacy. This is a supporting ingredient with a herbal tradition, not an active with solid clinical backing. It hydrates and improves feel, and it is often marketed as a tone-evening brightener, but independent evidence for that claim is thin. Treat it as a pleasant texture ingredient rather than a pigment treatment. Applied to skin its passage into the blood is minimal, so it can be used in pregnancy and breastfeeding. Tolerance is good. Irritation and allergy risk are low, which suits sensitive skin. It does not dry or clog pores. Caution only makes sense for people with a known grain allergy.
