Macadamia Ternifolia Seed Oil

Macadamia ternifolia seed oil is extracted from the nuts of the macadamia tree, native to Australia. It is a natural oil rich in fatty acids and antioxidants, commonly used in skincare as an emollient.In formulations, it works to soften the skin surface and help lock in moisture. Because of its molecular composition, it tends to absorb reasonably well compared to heavier plant oils, making it a popular choice in both face and body care products.

Macadamia oil's emollient action relies on its fatty acid composition, which sits on the skin surface and creates a barrier that slows transepidermal water loss. This helps the skin feel softer and more comfortable, particularly in dry or dehydrated states.The oil also contains antioxidants such as vitamin E and polyphenols, which may neutralise free radicals. However, the extent to which these compounds penetrate the skin barrier in cosmetic formulations remains unclear.

Macadamia oil is typically found in concentrations between 1% and 50% depending on the product type. In lighter formulations such as serums or lotions, it usually appears at lower concentrations. In richer creams or oils, it may be a primary component. Apply to damp skin to enhance hydration retention, and adjust frequency based on how your skin responds.

Macadamia oil is generally well-tolerated and suitable for most skin types. However, those prone to fungal acne may wish to patch-test first, as some plant oils can potentially feed certain fungal organisms; individual response varies.
