Ingredient review
Tribulus Terrestris Root Powder
INCI: TRIBULUS TERRESTRIS ROOT POWDER
A gentle botanical powder with antioxidant potential, but limited research supports its specific skin benefits.
In plain English
Tribulus terrestris root powder is made from the dried, ground roots of a prickly plant sometimes called puncture vine. In skincare, it is added for its antioxidant content, which may help protect skin from environmental stressors, and for its traditional use as a soothing ingredient. However, most research on this plant focuses on internal use, so its topical benefits are not well-established.
