Our take
Is Imperata Cylindrica Root Extract a Good Ingredient?
Rated Good because it's supported by supplier data and small studies showing improved short- to medium-term skin hydration, with a low history of irritation and good formulation stability. It works well as a complementary humectant in hydrating products, though the modest evidence base keeps it from Great.
