REVOX B77 JUST Collagen Amino Acids + HA is a moisturizing solution for face and neck. The solution combines the benefits of natural moisturizing factors (Collagen, Allantoin, Urea) with the hydrating power of the Hyaluronic Acid. The low weight of Collagen molecules allows their penetration in the skin, increasing its moisture levels and smoothing the complexion. This powerful moisture-binding complex reduces the appearance of new lines for younger-looking skin. The product targets the visible signs of aging.
