Ingredient review
Persea Thunbergii Extract
INCI: Persea Thunbergii Leaf/Root/Stem Extract
A gentle botanical extract with antioxidant potential, but research is still early and benefits are not yet proven in human skin.
In plain English
This is an extract from a tree called Persea thunbergii (also known as Machilus thunbergii), which grows in East Asia. In skincare, it's added to products like serums and creams to help protect skin from environmental damage and calm irritation. Think of it as a plant-based helper that may support your skin's natural defenses, but it's not a powerhouse ingredient on its own.
