Ultherapy
Overview
Focused ultrasound is one of the many energy technologies that have lately been created to address the ever-increasing public desire for considerable, noninvasive skin lifting and tightening. Focused ultrasound shares many characteristics with ultrasound used in medical imaging, however, it is highly convergent and uses different acoustic energy frequencies. Special transducers focus the ultrasound energy to create a small focused area where increased temperatures might trigger tissue coagulation. Similar to medical imaging, a focused ultrasound beam can be made to innocently pass through skin, allowing the main focus to target subcutaneous tissues like the superficial musculoaponeurotic system (SMAS), where the protein around the central focus will achieve over 65°C and be denatured within milliseconds.
