Natural Refined Vegetable Oil that improves the intrinsic properties of Macadamia Oil. It displays an optimal fatty acid composition profile that provides high antioxidant protection for cosmetic formulations.

Palmitoleic acid is found in human sebum among the young, but the level dramatically drops in mature skin.
