Hippophae Rhamnoides Extract is a plant extract from sea buckthorn (Hippophae rhamnoides, willow family).(1) In our formulation, we use an extract obtained from upcycled leaves, which is used as an antioxidant, skin-caring ingredient due to its composition (including phenolic acids, lipophilic compounds, vitamins, organic acids). Manufacturers report an improvement in the appearance of dark circles and puffiness as well as a fresher-looking eye area(2).
