Skin tightening procedures are non-surgical treatments used to stimulate new collagen and elastin to gradually lift and tighten skin in the deeper layers of the skin. Overtime, these treatments work to shrink tissue, reduce the appearance of fine lines, and tighten areas which have lost tone and elasticity. There are many types of non-invasive skin tightening approaches, but most effective laser energy, radiofrequency energy, ultrasound energy, or a combination of these energies to deliver heat to the skin tissue.
