Renuva is a groundbreaking treatment that gradually replaces age-related fat loss with your body's own fat. Renuva is injected where fat naturally exists, to replace volume where fat loss occurs. Renuva contains the same collagens, growth factors and proteins as your own fat. When injected, Renuva is gradually replaced with your own fat cells over the next few months. Post injection, new blood vessels and fat cell formation results in volume restoration – which helps you look natural, youthful and healthy.
