Uncaria Gambir Extract
What is Uncaria Gambir Extract?
Uncaria Gambir Extract derives from the leaves and twigs of Uncaria gambir, a woody climber native to Southeast Asia, particularly Malaysia and Indonesia. This botanical extract is rich in condensed tannins, including catechins and gambiriin, polyphenolic compounds responsible for its characteristic properties. In cosmetic formulations, it functions primarily as an astringent agent, typically incorporated into toners, cleansers, and tightening lotions at low concentrations. Upon application, the tannins interact with skin proteins, causing mild contraction of surface tissues. This mechanism delivers a subtle firming sensation, temporarily minimizing the visibility of pores and excess shine without penetrating deeply. Valued for its plant-based origin, the extract aligns with clean beauty trends, offering a gentle alternative to synthetic tighteners while contributing to product stability through its antioxidant components.
