Ultherapy is one of the best skin tightening treatments on the market as it is FDA approved and unlike other lasers, it uses ultrasound energy that allows it to bypass the surface of the skin and treat depths not matched by any other non-invasive machine. Ultherapy stimulates collagen production in the skin’s deeper layers which results in a significant lift of tissue. Other lasers use light energy which does not reach deeper skin layers so can only treat superficial skin.
