While both SkinTyte and SmartLipo are based on the principle of selective thermolysis to firm skin in targeted areas, there are differences in the way the lasers are used during treatment. SkinTyte is completely non-invasive. The SkinTyte laser is applied above the skin’s surface, utilizing pulsed light technology to deeply heat the skin while cooling and protecting the entire treated surface. SkinTyte can be performed quickly and comfortably with no anesthesia. The SmartLipo laser is placed beneath the skin through a tiny incision. For SmartLipo, a local anesthetic is used to numb the treatment areas and ensure that patients remain comfortable during the procedure.
