Ultherapy vs Thermage: Which Is Better?
THE SHORT VERSION
Ultherapy lifts deep tissue (the SMAS layer) with focused ultrasound and is best for sagging jowls and brows. Thermage FLX tightens skin with radiofrequency and is best for crepey texture and fine lines. Neither has downtime. For most people over 35, combining both on the same day gives the most complete result.
