Ultherapy does not melt fat. Ultherapy can target three different depths: the Dermis (deeper skin), Connective tissue (Superficial Musculoaponeurotic System-SMAS) and Muscle. The Superficial Musculoaponeurotic System (SMAS) is located below the fat and is a strong tissue that envelops the face. It is made up of collagen, elastic fibers and muscle fibers. The ultrasound energy produced during an Ulthera treatment, precisely and consistently heats the targeted tissue to 60-70 degrees centigrade, which is the optimal temperature for contraction and denaturation of collagen. The first stage is the contraction and denaturing of collagen, which causes an immediate tissue tightening, and resultant lift. The second stage occurs over time while the body’s healing response builds new collagen (neocollagenesis). New collagen production is generated over 2-3 months and often continues for 6 months after the treatment. Full results are visible after 3 to 6 months.If you have volume loss in addition to skin laxity, you will probably need fillers as well for facial volumization.In my practice we have had amazing results with Ultherapy. I recommend you receive your treatment from an Ultherapy expert. Good Luck!
