Macadamia oil is a natural oil extracted from the nuts of the macadamia tree, native to Australia. It is rich in monounsaturated fats, particularly oleic acid, which is known for its heart-healthy properties. The oil has a light, nutty flavor and is often used in cooking, baking, and salad dressings. In addition to culinary uses, macadamia oil is popular in the beauty industry for its moisturizing properties. It is commonly found in skincare products due to its ability to hydrate and nourish the skin. The oil is also used in hair care products to promote shine and manageability.
