Rheum Palmatum Root Extract

What is Rheum Palmatum Root Extract?

Rheum Palmatum Root Extract comes from the roots of Rheum palmatum, a perennial plant in the Polygonaceae family native to mountainous regions of China and Tibet, traditionally known as Chinese rhubarb. This botanical extract is rich in tannins, polysaccharides, and anthraquinone derivatives like emodin and rhein. In cosmetics, it falls into the category of plant-derived actives used in toners, serums, and masks. It functions by leveraging tannins to mildly contract surface skin proteins, producing a tightening sensation that refines texture and controls shine. Simultaneously, its conditioning components support skin's natural moisture retention and flexibility, while contributing to an invigorating after-feel through mild solvent-like refreshment. This dual action makes it suitable for formulations aiming to balance oiliness and enhance sensory appeal without harshness.
