Ingredient review
Nutmeg Kernel Extract
INCI: MYRISTICA FRAGRANS KERNEL EXTRACT
Nutmeg kernel extract offers antioxidant and soothing benefits, but research on its topical use is still limited.
In plain English
Nutmeg kernel extract comes from the seed of the nutmeg tree. In skincare, it's used as an antioxidant to help protect skin from environmental damage and as a soothing ingredient to calm minor irritation. It's generally gentle, but because it's a plant extract, people with very sensitive skin or nut allergies should patch test first.

What it is
A natural extract obtained from the kernel (seed) of Myristica fragrans, the nutmeg tree. It contains compounds like myristicin, elemicin, and various phenolic antioxidants.
