AT A GLANCE
Ultrasound treatment such as Ultherapy Prime uses focused ultrasound with imaging that lets the clinician see tissue, whereas radiofrequency treatment such as Thermage FLX delivers RF energy through a treatment tip. RF microneedling, as with Potenza, is a third method in which needles enter the skin, so the device and method need naming as well as the energy type.
How are ultrasound and radiofrequency delivered?
Ultrasound and radiofrequency are delivered through different device methods, which need to be named as well as the energy type. Prime's ultrasound imaging lets the clinician see tissue during treatment. FLX applies RF energy through a treatment tip. Potenza combines RF with microneedling, in which needles enter the skin and energy heats tissue; it is not the same procedure as surface-applied RF.
At Jcell, Ultherapy and Thermage illustrate different energy-device discussions. RF microneedling is another method and should not be treated as identical to a surface RF treatment simply because both use the letters RF. Ask the clinician to name the device, explain the procedure and connect it to the examination. Avoid using depth numbers from an online comparison to choose your own treatment settings.
The FDA's October 2025 RF microneedling communication reports burns, scarring, fat loss and nerve damage with certain uses. That category warning is neither a Jcell-specific finding nor a Korean approval statement. Device-specific information matters because one technology label can cover different methods and risk discussions. Use this explanation to understand a proposal, then consult the Ultherapy–Thermage comparison for the patient decision and the combination guide if both procedures are suggested.
Which technology details should I clarify?
- Which device and method are being proposed?
- How does that method relate to the area you examined?
- Which risks and limitations are specific to this procedure?
Your questions
Does deeper treatment automatically mean a better result?
No. The intended target and individual anatomy matter. Ask why the clinician proposes a particular approach; greater depth is not a general measure of quality.
