What it is
Macadamia integrifolia seed oil is expressed from the seeds (nuts) of the macadamia tree and is rich in fatty acids, notably oleic and palmitoleic acids. It functions as an emollient and skin-conditioning oil, leaving a soft, cushioned feel and helping smooth the skin surface. It is used in sunscreens, creams, and balms as a nourishing oil phase component.
Safety & warnings
Macadamia seed oil is generally well tolerated and valued for its emollient feel. Like many nut-derived oils it can have moderate comedogenic potential and may not suit very acne-prone skin. People with tree nut allergies sometimes prefer to be cautious, though refined oils are widely used in cosmetics. It is not a fragrance allergen.
Origin & sourcing
A natural plant oil obtained by pressing the seeds of the macadamia tree (Macadamia integrifolia).
