Ultherapy uses sound energy – tried-and-true ultrasound – which has unique properties that allow it to bypass the surface of the skin to treat depths not matched by any other non-invasive cosmetic device. Ultherapy ultrasound stimulates collagen production in the skin’s foundation, resulting in a clinically significant lift of tissue over 3-6 months.  Lasers rely on light energy, which cannot reach deeper skin layers at an optimal temperature, so laser treatments typically only treat superficial skin and are not FDA-cleared to lift skin.  Since the two technologies often treat different types of skin issues, they’re actually very compatible.
