Essential Nine includes Aloe, Chamomile, Green Tea, and three clinically proven active ingredients to reduce eyelid and under eye puffiness, dark circles and redness while deeply hydrating to minimize fine lines. Active ingredients include Eyeseryl, Regu-Age, GatulineA and Pentavitin. Essential Nine is unscented and non-irritating to the eyes, and it absorbs quickly, leaving the skin silky smooth. Made in the U.S.A. A 1 oz. bottle provides approximately 70 pumps. More about E9's predominant ingredients: Sodium Hyaluronate is a salt of hyaluronic acid which has a much lower molecular size, thus it can penetrate the skin when applied topically. Sodium Hyaluronate holds 1000 times its weight in water and makes it an excellent moisturizing ingredient - it not only hydrates the skin, but helps to reduce water loss and gives an immediate slight swelling of skin that helps to minimize the appearance of fine lines and wrinkles. Eyeseryl (Acetal Tetrapeptide-5) is an amino acid peptide which demonstrates the ability to correct fluid retention in the facial areas and dramatically reduce the decomposition of collagen. Eyeseryl has proven efficacy in reducing puffiness related to under eye bags, improving skin elasticity and enhancing skin texture and smoothness.
