Ingredient review
Cedrela Sinensis Leaf Extract
INCI: CEDRELA SINENSIS LEAF EXTRACT
A gentle plant extract that may help protect skin from environmental stress, though research is still early.
In plain English
Cedrela sinensis leaf extract comes from the leaves of a tree sometimes called Chinese mahogany or toon. In skincare, it's added for its antioxidant content, which can help neutralize free radicals (unstable molecules that can damage skin cells). It also has mild soothing properties, making it a nice addition for sensitive or irritated skin. Because it's a natural extract, its effects are gentle and not as potent as some lab-made antioxidants.
