FAB�۪s Detox Eye Roller contains caffeine, a potent vasoconstrictor that constricts the fine blood vessels that cause dark undereye circles. Hyaluronate and advanced peptides recapture lost volume and increase collagen production to reduce fine lines. Witch hazel protects and soothes the very delicate skin under the eye. The unique delivery metal roller ball gently distributes lymphatic build-up from underneath the eyes, resulting in less baggy looking skin. Within minutes of application, the appearance of the undereye area is improved with more dramatic results over time.
