Torreya Nut Extract
INCI: Torreya Nucifera Extract
A gentle, plant-based antioxidant that may help protect skin from environmental stress, though human studies are limited.
In plain English
Torreya nut extract comes from the seeds of a Japanese evergreen tree. It contains compounds that can help shield your skin from damage caused by pollution and UV light, similar to how vitamin C works but from a different plant source. It's generally very mild and unlikely to cause irritation.
