Hippophae rhamnoides extract is a plant extract derived from sea buckthorn (Hippophae rhamnoides, family Elaeagnaceae).(1) In our formulation, we use an extract derived from upcycled leaves, which, due to its composition (including phenolic acids, lipophilic compounds, vitamins, and organic acids), is used as an antioxidant and skin-nourishing ingredient. According to the manufacturer, it improves the appearance of dark circles and puffiness and leaves the eye area looking fresher.(2)
