This nourishing face serum is a very special serum in my recipe book. Made with four of my favorite skincare oils, this blend is deeply hydrating and delivers a flattering bronze tint that can suit many skin tones. The star of this recipe is sea buckthorn oil, which in my opinion is a misused oil that doesn't get the fame it deserves. While most skin care oils are pressed from the seeds of a particular plant, sea buckthorn oil it is pressed from seeds and berries that gives it a vibrant golden hue and contains abundant antioxidants, vitamins, minerals and essential fatty acids. Sea buckthorn oil also contains linoleic acid, which has been shown to support the skin's lipid barrier, helping to reduce overall moisture loss. For all these reasons, it remains high on my list of favorite skin care ingredients.
