Macadamia integrifolia oils contain approximately 13–18% palmitoleic acid, omega7. This is very beneficial for mature skin, dryness and barrier function to retain moisture. Very few plant oils contain omega7 at this concentration apart from Sea Buckthorn fruit oil but because of its colour it may stain or give a yellowish tone to your skin care.

Macadamia oil also contains tocopherols and tocotrienols, the full spectrum of natural vitamin E as well as a small amount of squalene, a naturally occurring emollient.
