What is Macadamia Ternifolia (Macadamia) Seed Oil?

Macadamia ternifolia seed oil comes from the kernels of the macadamia nut tree, native to Australia, extracted typically by cold-pressing for cosmetic use. This pale yellow vegetable oil is rich in monounsaturated fatty acids, primarily oleic acid around 60%, along with palmitoleic acid that resembles human sebum lipids. In skincare products like moisturizers, serums, and balms, it acts as an emollient by spreading easily to fill skin crevices, enhancing texture and slip. It supports the skin's natural barrier through its occlusive-like properties when blended with other ingredients, aiding in lipid replenishment for smoother, more supple skin. The oil's composition includes natural tocopherols contributing to stability. Commonly found in natural and luxury formulations, it absorbs readily without greasiness, making it suitable for various skin types in leave-on and rinse-off products.
