Teosyal Puresense Redensity 1 is a medical grade injectable treatment that consists of hyaluronic acid, amino acids, antioxidants, minerals and vitamins. Instead of applying nutrients to the surface of the skin, often failing to reach the deeper layers, Redensity 1 is injected into the dermis nourishing from within. By replacing hyaluronic acid and nutrients to the skin Redensity 1 restores hydration, skin tone, and elasticity and helps to stimulate collagen production. Areas that can be treated are the face, neck, décolleté and hands.
