Caviar extract is harvested from fish roe and packs some of its source’s nutrients, like essential fatty acids and protective antioxidants. Caviar extract’s antioxidant properties help defend skin from free radicals, or molecules that can damage cells and destroy collagen. Fatty acids omega-3 and omega-6, on the other hand, hydrate skin and help maintain its moisture barrier. Fatty acids benefit hair, too, by moisturizing strands and restoring shine.
