Why is the effect different after 300 rounds of Ultherapy ultrasonic scalpel? The key is not just the number of shots, but the layers, locations and ultrasound images.
Do the same Ultherapy (American version of ultrasonic scalpel) 300 rounds , why do some people’s jaw lines tighten significantly, while others feel there is not much change? The answer is usually not just “whether the number of rounds is enough”, but whether the 300 rounds are designed according to the individual’s skin thickness, fat distribution, SMAS fascial layer depth and relaxation direction.
1. Why do the same 300 rounds produce different effects?
Everyone’s face shape, skin thickness, fat amount and facial volume are basically different, and the position of the SMAS fascial layer is not fixed. Generally speaking, the target layer may be deeper in people with thicker tissue and shallower in people with thinner tissue, but appearance does not reliably predict internal structure in all people.
If the target layer is close to 5mm, the fitting and pressing method of the 4.5mm probe is very important; if the target layer is shallower, the 3.0mm probe may be closer to the planned level. This is not simply to say “the deeper the better”, but to make the thermal coagulation point fall as far as possible on the tissue layer where it is planned to act.
2. Can Ultherapy itself see ultrasound images?
Yes. One of the important features that distinguishes Ultherapy from many energy devices is that it provides real-time ultrasound visualization during treatment. The doctor can observe the subcutaneous tissue, confirm the probe contact, and adjust the layer and procedural path accordingly.
According to the official instructions for use of Ulthera System, the device can be used in treatment depths such as 1.5mm, 3.0mm and 4.5mm, and can use images to assist in observing tissues and formulating plans. It should be noted that, Additional diagnostic-grade ultrasound examination is not a must for everyone before doing Ultherapy ; It can provide more reference when the anatomical level is difficult to judge, the patient has received multiple fillings or energy surgeries in the past, and the tissue thickness is significantly different.
3. Where do the 1.5mm, 3.0mm and 4.5mm probes function respectively?
| Common depth | main target level | Design focus |
|---|---|---|
| 1.5mm | Superficial dermis | For use on more superficial skin areas, avoid applying the same parameters to all areas. |
| 3.0mm | Deep dermis and subcutaneous fibrous tissue | Commonly used for skin thickness and superficial tissue tightening designs. |
| 4.5mm | SMAS/Platysma and other deeper fibrous layers | Used for deep structural lifting, but not every area is suitable for heavy use. |
Official information shows that Ultherapy uses micro-focused ultrasound to form thermal coagulation points at the planned depth, and then initiates tissue contraction and collagen remodeling. The task of different probes is not to “strength level”, but to put energy at different levels.
4. Will my face become sunken after using Ultherapy?
Ultherapy does not necessarily lead to fat loss or sunken cheeks. The risk is related to the basic face shape, fat distribution, action site, depth, energy and hair number arrangement.
- Appropriate tightening of the mandibular margin or areas where fat is relatively concentrated may make the contours clearer.
- The temples, cheeks, or areas that lack volume of their own need to be sparingly reserved.
- If you use the same depth and density for your entire face, you may not be able to achieve both lifting and volume protection.
The positioning of Ultherapy is to lift and tighten, not to fill in depressions. If facial aging also includes fat loss, loss of bone support, or significant depression, ultrasound lifting alone cannot solve all the problems.
5. Why would someone match Thermage or Density?
Ultherapy uses micro-focused ultrasound, focusing on deeper structures and contours; Thermage FLX, Density and other radio frequency devices focus more on extensive heating and elasticity improvement of skin and subcutaneous tissue. The two types of equipment do not have to be used together, but when “deep relaxation” and “decreased skin elasticity” exist at the same time, the doctor may design a joint plan according to the situation.
6. How long does it take for Ultherapy to become effective? How long can it last?
Some people will feel firmer due to immediate tissue contraction after the procedure, but the more important change comes from subsequent collagen remodeling, which usually takes weeks to months to gradually appear.
There are individual differences in the maintenance time. The common re-evaluation period is about one year, but not everyone should do it once a year. Skin thickness, laxity, age, lifestyle habits and previous procedural history will all affect the re-evaluation time.
7. What should I ask the doctor before taking Ultherapy?
- Is my main problem loose skin, fat migration, or lack of volume?
- Which probe depths are planned to be used and in what areas will each be used?
- How to distribute 300 rounds to the mandibular edge, midface, neck or other parts?
- Are areas that lack volume inherently being avoided?
- Is the equipment genuine Ultherapy? Can the probe and operation records be verified?
- Are real-time ultrasound images used to confirm tissue and probe fit?
- How to review when persistent pain, numbness, facial asymmetry, etc. occur?
8. FAQ
Is 300 rounds of Ultherapy enough?
There is no fixed answer that works for everyone. Whether 300 rounds is enough depends on the scope of the operation, the area of the face, the degree of relaxation, and the allocation of the number of rounds to each layer.
Is the effect better with more rounds?
Not necessarily. Increasing the number of rounds is not a substitute for layer judgment and may increase pain, swelling, or unnecessary energy exposure. Reasonable distribution is more important than simply pursuing the total number of rounds.
Are the Ultherapy and the Korean version of the ultrasonic scalpel the same device?
no. Ultherapy is a specific brand of micro-focused ultrasound equipment; Ultraformer MPT, Shurink Universe and other HIFU equipment belonging to other brands cannot be confused with just three words “ultrasound scalpel”.
Is it necessary to do additional diagnostic ultrasound before treatment?
Not everyone has to. The Ultherapy itself has a real-time imaging function; additional diagnostic ultrasound can provide more information when the tissue level is difficult to judge, or when previous filling or treatment history is complicated. The doctor should judge whether it is needed.
