The Ingredient

Black cumin hides its most interesting part inside an unusual inflated seed capsule. As the capsule matures, it fills with small, angular black seeds—the source of the deep amber oil. Naturally rich in linoleic and oleic fatty acids, black cumin seed oil helps soften, condition, and support the skin’s protective barrier while also providing naturally occurring antioxidant compounds.

A Closer Look

Black cumin's tiny black seeds develop inside an inflated capsule that almost looks architectural. When mature, the capsule dries and opens to release the angular seeds inside. Those unassuming seeds contain both the oil and thymoquinone, one of the naturally occurring plant compounds that has made Nigella sativa the subject of considerable scientific interest.
