Persimmon Leaf Extract
INCI: Diospyros Kaki Leaf Extract
A gentle, plant-based antioxidant that helps calm skin and defend against environmental stress, but research is still emerging.
In plain English
Persimmon leaf extract comes from the leaves of the persimmon tree. It's rich in natural compounds called flavonoids and tannins that can help protect your skin from damage caused by pollution and UV rays. Think of it as a mild shield that also helps calm redness or irritation. It's not a powerhouse ingredient on its own, but it works well alongside other antioxidants like vitamin C or E.

What it is
An extract derived from the leaves of the persimmon tree (Diospyros kaki), containing bioactive compounds such as flavonoids, tannins, and phenolic acids.
