It sounds as though Ulthera might be more effective than Thermage. Is it because it goes to the SMAS layer, or because images of the tissue can be seen during the procedure, or both? Does Thermage reach the SMAS layer as well? Thank you.

Thermage vs. Ulthera
Comparing Thermage and Ulthera is not a task as the procedures are very different. Thermage uses electrical energy to heat the skin to varying depths. Heating produces collagen remodeling and some tightening. Ulthera uses focused ultrasound to deliver small, focused heat source to deeper tissues. This can also resutl in tightening. Thermage is well adapted for use on the body whereas Ulthera is still a bit less efficient for use off the face although this is expected to change with time. Both devices can be used effectively in some patients; side by side comparison studies have not been reported.
Penetration levels not the only difference between Thermage and Ulthera
Having used both technologies extensively, my opinion is that they work differently in that Thermage generally gets superfical rejuvenation more than lifting, Ulthera the other way around. It is true that Ulthera, which uses highly focused ultrasound energy, can be applied with great precision at the level of the SMAS, a collagen-rich layer under the facial skin, and the imaging is an advantage by confirming that you are at the depth that you want. Because Thermage requires conduction of a current through the tissue, it isn't as focused but can penetrate deeply to some degree.
