Why Measure Skin Thickness With Ultrasound?

The reason for measuring skin thickness with an expensive ultrasound machine -

The reason for purchasing an expensive ultrasound separately to examine the skin is for more accurate results.

Hello, I am Director Kim Ga-eul. Many people ask this question. 'Do you really measure skin thickness with ultrasound?' Yes, that's correct.

And this process is a very important step that determines the accuracy of the Ultherapy procedure.

✴️Skin thickness is different for everyone

Even within the same face, the skin thickness varies by area.

For example, the structure of the cheeks, forehead, and jawline is different.

Also, even on the same body part, the amount of skin thickness and subcutaneous fat varies from person to person.

Therefore, the concept of "just shooting at a predetermined depth"

is actually hard to consider as an accurate lifting method.

🎯 Ultherapy is all about 'depth'

Ultherapy is a device that accurately delivers ultrasound energy

to a specific depth.

If the tip is marked with 4.5mm as shown in the above photo,

it means targeting a depth of 4.5mm from the skin surface.

This is almost at the same depth as the 5mm (0.5cm) point seen on the ultrasound screen.

In other words,

after checking the current thickness of my skin and the position of the fat layer with ultrasound,

you have to choose the appropriate tip to reach the desired layer (SMAS layer) precisely.

🫧Reasons for viewing ultrasound Even for the same person, as shown in the above screen, the thickness of subcutaneous fat can vary depending on weight changes, swelling, and fat condition.

Therefore, real-time confirmation before the procedure is important.

💰 Reasons why Ultherapy is expensive

Ultherapy is not a cheap procedure. Usually, it costs over 1 million won for 300 shots. For that reason,

✔ checking the layers with ultrasound, ✔ selecting the appropriate tip for each area, and ✔ adjusting the depth must be included

to finally achieve ‘accurate Ultherapy’. If a place is excessively cheap based only on cost,

there is a possibility that they might not see the ultrasound sufficiently or not carefully change the tips for each area.

💫Summary of today

Ultherapy is not just about the number of shots

but about where, at what depth, and how accurately it enters. is the key.

The reason for viewing the ultrasound is simple.

It is to achieve the safest and most accurate lifting suitable for my skin condition.

Frequently Asked Questions

Q1. Why does Ultherapy require an ultrasound scan before treatment instead of just picking a standard depth?

Skin and fat thickness vary a lot between people and even between areas of the same face, so a single preset depth would miss the target layer for many patients. Scanning first lets the provider see the current thickness and fat position and choose the tip that actually reaches the SMAS layer. This is part of why the procedure is considered more precise than a one-size-fits-all approach.

Q2. Does a higher Ultherapy price mean the clinic is doing something different?

Cost differences often come down to whether ultrasound imaging and tip selection are actually being used for each area rather than skipped. A price that looks unusually low compared to others may mean less thorough scanning or fewer tip changes per area. It's worth asking directly whether ultrasound guidance is included as standard, since pricing and protocols vary by clinic.

Q3. How is the treatment depth chosen for Ultherapy tips like the 4.5mm one?

Tips are marked with a target depth, such as 4.5mm, meaning the energy is meant to focus at that distance below the skin surface. The provider checks this against what's visible on the ultrasound screen to confirm it lines up with the SMAS layer for that particular area. Because thickness differs by region and by person, this matching step is done individually rather than applied uniformly.

Q4. Who tends to need more careful depth assessment with Ultherapy?

Anyone whose skin or subcutaneous fat thickness has changed recently, for example due to weight fluctuation or swelling, may benefit from a fresh ultrasound check rather than relying on an old assessment. Since thickness can shift over time even for the same person, real-time imaging before the procedure helps confirm the current state. A consultation with imaging is the most reliable way to know what applies to your case.
