Profhilo is a HA (Hyaluronic Acid) gel, which is designed not to simply add volume but to bio-remodel the skin. It was developed using patented technology resulting in hybrid cooperative complexes between high molecular weight hyaluronic acid and low molecular hyaluronic acid without the use of any chemical cross-linking compounds. Profhilo stimulates four types of collagen (I, III, IV, VII and elastin) and does this thanks to slow and long lasting release of hyaluronic acid from the hybrid complexes action on fibroblast and keratinocytes. This unique formulation works to restore elasticity, skin tone and deep hydration while lifting and tightening the skin.
