How Does The Hyaluronic Expert Energetic Eye Roller Works? Hyaluronic Expert Energetic Eye Roller is primarily aimed at visible skin problems around the eyes. This formula contains high levels of caffeine in addition to kojic acid. This combination of active ingredients works synergistically to reduce visible dark circles and contour puffiness. Hyaluronic Expert Energetic Eye Roller penetrates deep into damaged skin and stimulates the production of new collagen, a protein that helps skin appear plump and firm. This eye roller effect on skin resulted in a reduction in dark circles, puffiness, fine lines, and wrinkles. OUR GUARANTEE We are confident that we offer some of the best products on the market.
