Factor-A® Eyes For Dark Circles With Vitamin K, Retinol, and Supporting Agents Addresses Darkened Color, Lines, Wrinkles, and Other Signs of Aging Around the Eyes Under-eye darkness can result from a combination of different factors. These factors can include: Thinner skin on the lower eyelids allowing pigment and vessels to be more visible. Gravity, which causes under-eyelid skin to move downward, initiating more stretching and thinning. This allows the blood vessels and pigment to become more noticeable. Cumulative sun exacerbates the skin-thinning, melanin content, and effects of gravity. Inflammation. Jan Marini Skin Research Factor-A Eyes is a medically researched and tested formulation that dramatically addresses the combination of these contributing factors by utilizing Vitamin K, Retinol, and a number of supporting agents in a highly stabilized polymeric controlled release system. Vitamin K has been shown in clinical studies to assist in decreasing the appearance of pigment and repairing blood vessels. Retinoids (such as stabilized retinol) have historically been proven to decrease the appearance of lines and wrinkles, reorganize collagen and assist in preventing the deposit of pigment in the epidermis. The combination of these two ingredients directly addresses the appearance of darkened color, lines, wrinkles, and other signs of aging around the eyes. Users report rapid and noticeable improvement. Factor-A Eyes for Dark Circles is packaged in 60 individually encapsulated and stabilized dosages. Used once daily in the evening, one capsule is used for both eyes. The gel-like, time-release formula is gently applied to the under eye area. 60 individually encapsulated dosages (2-month supply)
