Cyperus Rotundus Oil: What It Is, What the Research Says, and How We Test It

The ingredient ✿
Everything you'd want to know about the main ingredient in Caramela's oil: where it comes from, what the published research says, and how every batch is tested before it reaches you.
What is Cyperus rotundus?
Cyperus rotundus, also called nutgrass, is one of the oldest botanicals in the world. It has been used for generations, going back to ancient Egypt, in skincare and for the look of finer, softer hair. In our oil it is the main ingredient, blended with nourishing oils like jojoba, rosehip, sweet almond, and aloe. It is a topical you apply to the surface of your skin.
What the research says
Cyperus rotundus has been studied in published research, including a clinical study. In a 6-month study of 91 women with unwanted hair, participants reported finer, less noticeable hair, with no irritation and no allergic reactions reported. In that same study, researchers measured participants' blood testosterone at the start and again at six months, and the levels stayed essentially the same.
