Almost 90% of macadamia oil is made up of 3 fatty acids; oleic acid, palmitoleic acid, and palmitic acid. Oleic acid is a monounsaturated, omega-9 fatty acid that moisturizes the skin and acts as an anti-inflammatory. It helps skin cells regenerate quickly, keeping skin smooth and supple. Palmitoleic acid is a monounsaturated, omega-7 fatty acid that helps to prevent burns, wounds and skin scratches. It is the most active anti-microbial in human sebum and is surpassed only by palmitic acid as the main fatty acid in sebum. Palmitic acid is a saturated fatty acid that helps maintain the skin’s healthy barrier function, by forming an occlusive layer on the surface.
Skin’s sebum consists of a number of complex lipids, such as, triglycerides, wax esters, and squalene. As we age, the production of sebum changes in both quantity and in composition. In early adolescence, our sebum production increases until we are in our 20’s and 30’s, where it begins to decline. The amount produced varies between males and females, with females experiencing a more noticeable decline around the age of 40. (No wonder we get dry skin when we go through menopause. The composition of our sebum also changes with age. The two main fatty acids of human skin sebum are palmitic acid (22.5%) and palmitoleic acid (21.8%). The level of palmitic acid in sebum remains fairly constant throughout our lives. However, the production of palmitoleic acid starts to decline once we are in our 20’s. My research indicated it is not comedogenic.
While all the scientific information seems good, it gets even better when you talk to people who have been using it a while. It is particularly helpful to maturing skin. Its composition lets it soak in more deeply than other oils so the skin becomes better hydrated and skin seems to “recognize” the components and make use of them. As a skin care professional I use a lot of wonderful serums and products on my face, but I have never found a body product I could stick with – until now. I have only been using it less than 3 weeks, but my skin is softer, smoother, firmer with no hint of the former dry flakiness. Feel free to do your own test. Buy a bottle and try it twice a day for at least a month (how long it takes for the skin to completely turn over) and send me a message with your results.
