What Is Caesalpinia Benthamiana Root Extract?
Caesalpinia Benthamiana Root Extract comes from the roots of Caesalpinia benthamiana, a small leguminous tree native to tropical West Africa. Traditional healers have long boiled or pounded the roots to soothe irritated skin, a folk use that sparked interest among modern formulators. The root is rich in polyphenols, flavonoids and tannins, molecules known for their ability to fend off environmental stressors and reinforce the skin’s natural barrier.
To produce the cosmetic grade extract, harvested roots are washed, air-dried then milled into a coarse powder. The powder is soaked in a skin-safe solvent like glycerin or ethanol, allowing the beneficial compounds to leach out. After filtration and gentle evaporation, the concentrated liquid is standardized for consistency before being blended into finished products.
You will most often spot this botanical in soothing masks, barrier-boosting moisturizers, after-sun lotions, anti-aging serums and leave-on treatments aimed at reducing the impact of pollution and daily wear.
