Yes, there is a key difference. HIFU (High-Intensity Focused Ultrasound) is a general term for ultrasound-based skin tightening treatments, whereas Ultherapy is the original, patented version of this technology.
Ultherapy stands out because it includes real-time ultrasound imaging, allowing practitioners to see the exact layers of skin they are targeting. This precision reduces risks and ensures optimal results.
Copycat HIFU machines do not have this imaging feature, meaning the treatment is done blindly, without the ability to visualise skin depth. This increases the risk of uneven results or complications.
