Ingredient review
Horopito Leaf Extract
INCI: Pseudowintera colorata leaf extract
A gentle botanical extract with antioxidant potential, but research on its cosmetic benefits is still limited.
In plain English
Horopito leaf extract comes from a New Zealand shrub also called red horopito or New Zealand pepper tree. In skincare, it's used mainly for its antioxidant properties, meaning it can help protect your skin from damage caused by environmental stressors like pollution and UV rays. It also has some natural antimicrobial activity, which might be helpful for oily or blemish-prone skin. However, most of the evidence comes from lab studies, and more human research is needed to confirm its effects in skincare products.
