Ultrasound and radiofrequency tightening overview
Ultherapy microfocused ultrasound and the radiofrequency devices that compete with it all go after the same job, which is tightening skin that has begun to sag. Skin tightening is optional care, so it sits at the bottom of any triage list. Nothing here is urgent, but the questions you ask before treatment are worth getting right.
Start with Cleveland Clinic's Ultherapy page and the ASDS piece on ultrasound therapy for sagging skin. Then read how the radiofrequency side is described in a systematic review of subsurface radiofrequency treatments and a separate paper on radiofrequency in aesthetic surgery. When the two sides describe the same device differently, note the difference and ask your clinician which description matches the machine they use.

Your device question list
Pick the device you have been offered and read its page first. Then write down what you want to ask: how many sessions are planned, what the device does to the skin, what the recovery looks like, and which reactions after treatment mean you should call the clinic the same day. Get that list in writing before the visit, and use it if something feels wrong afterward.
An independent publication with no device to sell wrote this overview, and it is not medical advice.
