Ultherapy is a non-surgical, non-invasive procedure that uses ultrasound and the body’s own natural healing process to lift, tone, and tighten loose skin. Ultherapy can be used on many parts of the body, but it is especially for moderate skin laxity on the neck. The procedure utilizes ultrasound energy to stimulate the deeper layers of the dermis to produce collagen without disturbing the surface of the skin.
