Oubaku Ekisu
What is Oubaku Ekisu?
Oubaku Ekisu is a botanical extract obtained from the bark of Phellodendron amurense, the Amur cork tree native to East Asia, including parts of China, Japan, and Russia. Belonging to the Rutaceae family, this tree's bark yields an extract rich in alkaloids like berberine and palmatine. In cosmetic formulations, it functions primarily as a skin conditioning agent, helping to preserve the skin's moisture barrier and enhance its texture. Commonly found in creams, lotions, and serums, it supports the skin's natural suppleness without contributing to pore blockage. Its mild profile stems from traditional use in Asian herbal preparations, now adapted for modern skincare where it integrates seamlessly to promote a balanced feel.
