This laser uses the most advanced cooling system to cool the surface of the skin, thus allowing the use of higher energies to penetrate deeper into the skin for more impressive results. The heat from the laser causes immediate tissue tightening and signals the body to start making new collagen. As the new collagen forms, skin will be tighter and firmer. The 1064 Tightening Laser is best for diminishing fine lines, scars, and wrinkles. It effectively tightens and brightens the skin.
