Shurink vs. Ultherapy — Why Depth Settings Make All the Difference
Shurink vs. Ultherapy: Where the 4.5mm Single-Depth and Multi-Tip Approaches Diverge
Shurink vs. Ultherapy — Why Depth Settings Make All the Difference
Last Friday, a 49-year-old patient came into the clinic and asked,
"Ultherapy costs more, so it must be better, right?"
Her concern wasn't overall facial sagging —
she was focused on just one thing: her jawline.
In cases like hers, the answer is actually a bit different.
The bottom line. Shurink and Ultherapy are both HIFU devices, but they differ in how they manage depth.
The deciding factor. Whether you need a single 4.5mm depth, or the flexibility to switch between 1.5mm, 3.0mm, and 4.5mm tips.
What we're covering today. How to determine which option is better suited to your specific area of concern.
How the depth design differs between Shurink and Ultherapy
Why tip-switching gives Shurink an edge along the jawline and thinner areas
Who gets better value from each — and who doesn't
Shurink vs. Ultherapy — What's the Difference in Depth?
Shurink is a HIFU device that switches between 1.5mm, 3.0mm, and 4.5mm tips depending on the treatment area. Ultherapy is a HIFU device built around two core depths: 3.0mm and 4.5mm.
Both devices work on the same principle —
they concentrate high-intensity ultrasound energy at a single point,
creating thermal coagulation points that trigger tissue contraction.
The difference lies in how precisely each device can address different tissue layers.
Ultherapy's strength is the 4.5mm SMAS Layer depth — it excels at correcting deeper, more significant sagging.
Shurink has the added advantage of a 1.5mm tip that reaches the Dermis,
allowing it to address Fine Lines around the mouth and thinner areas along the jawline.
For reference, Shurink's 1.5mm tip does penetrate to approximately 1.5mm depth.
On ultrasound imaging, subcutaneous fat tends to compress when pressure is applied,
but the Dermis shows almost no such change —
which means energy is delivered precisely to the 1.5mm target.
Why Does Tip Selection in Shurink Change Results by Area?
Simply put, tip selection near the jawbone determines the outcome.
Key Insight from Dr. Wi Young-jin
Both Shurink and Ultherapy are HIFU devices,
but Ultherapy's strength lies in its 4.5mm single-depth power, while Shurink's advantage is the flexibility to switch between 1.5mm, 3.0mm, and 4.5mm tips for area-specific customization.
When the goal is to address even a thin jawline, Shurink's multi-tip approach offers a clear advantage.
There's a common misconception I hear often:
"Ultherapy is more expensive, so it must be better" —
and whether that's true or not really depends on the area being treated.
Let me use the jawline as an example.
If you deliver 4.5mm depth energy directly near the jawbone,
that energy can reach the bone itself.
This area is where the marginal mandibular nerve runs close to the surface,
and it's actually marked as a contraindicated zone on the Ultherapy device's own display screen.
So in this area,
the correct approach is to target only the SMAS Layer precisely at 3.0mm,
while Fine Lines around the mouth and superficial Dermis sagging require a separate 1.5mm pass.
Shurink can handle this by switching tips,
while Ultherapy has a clear identity as the 4.5mm deep-sagging specialist —
but it simply doesn't address shallow depths like 1.5mm.
This can be hard to grasp from text alone, but it becomes very clear when you look at actual cases.
The 49-year-old patient I mentioned earlier
had virtually no overall facial sagging —
her concern was limited to a single line along the jawline and Fine Lines around her mouth.
On ultrasound imaging, the subcutaneous fat near the jawbone was quite thin,
leaving little room to safely apply 4.5mm depth.
I focused primarily on Shurink's 3.0mm tip to target the SMAS Layer,
then finished the area around the mouth with the 1.5mm tip.
When she came back two weeks later,
she said, "I wasn't expecting much, but my jawline came together faster than I thought."
On the other hand, a 44-year-old patient
presented with a heavier overall facial volume
and widespread SMAS Layer descent across a broad area.
For patients like her, Ultherapy's approach — delivering deep, uniform 4.5mm energy across the SMAS Layer — produces cleaner, more consistent results.
When a patient has a higher BMI and thicker subcutaneous fat,
even with Shurink, the proportion of 4.5mm shots needs to be increased accordingly.
Dr. Wi Young-jin's Key Summary
Ultherapy is the go-to for deep sagging at 4.5mm,
while Shurink's strength is area-specific customization through 1.5mm, 3.0mm, and 4.5mm tip switching.
If you need to address a thin jawline or the area around the mouth, Shurink's multi-tip approach gives you more precise control.
For deep, widespread facial sagging, Ultherapy delivers cleaner results.
Shurink vs. Ultherapy — Who Should Reconsider Each Option?
Let me be straightforward about where the cost-to-benefit ratio diverges.
Looking at it this way, the difference becomes clear.
Let me also address the cases where each approach is not recommended.
For patients with a narrow jaw and minimal subcutaneous fat,
treating the entire jawline with a single 4.5mm depth is not advisable.
There is a risk of nerve stimulation,
and when energy goes primarily into muscle without reaching the intended tissue,
you're left with Pain during and after the procedure — with little visible improvement.
Conversely, for patients with a higher BMI and widespread SMAS Layer descent,
relying primarily on the 1.5mm tip is
the most common pattern of poor value —
patients often report, "I had it done, but the change was barely noticeable."
That said, neither device is universally superior.
Without using ultrasound imaging to assess tissue thickness first,
simply saying "let's use all the Shurink tips" or "Ultherapy is always better"
won't yield good results with either device.
However, if you understand where your own condition falls on this spectrum,
making the right choice becomes much easier.
Shurink vs. Ultherapy — 3 Questions I Hear Most in the Clinic
Q1. If Ultherapy costs more, does that mean it's more effective?
A. In short — it depends on the area.
For deep, widespread facial sagging, Ultherapy delivers a stronger single-session impact.
But for areas that need attention at a shallower level — like the jawline or around the mouth — Shurink's multi-tip flexibility produces cleaner results.
Price doesn't determine effectiveness. The depth of your sagging does.
And here's another question I get asked very often:
Q2. How many sessions of Shurink do I need, and how far apart?
A. This is the part that confuses most patients.
Shurink is typically scheduled at shorter intervals than Ultherapy.
A standard protocol is about 3 sessions, spaced 3 weeks apart.
Every month or two, someone asks, "Can't I just do it once every 6 months?"
But Shurink is designed for cumulative effect — the key is to progressively stabilize the SMAS Layer through closely spaced sessions.
And there's one more point I always make sure to cover before we wrap up:
Q3. What about Pain and side effects when treating the jawline?
A. It varies from patient to patient,
but most people find it manageable with topical numbing cream — though Pain does scale with energy level and depth.
If nerve stimulation is a concern, adding a nerve block injection makes the procedure significantly more comfortable.
Applying 4.5mm depth directly near the jawbone can occasionally cause temporary asymmetry around the mouth —
it's not common, but it's not zero either.
The safest approach is always to assess tissue thickness with ultrasound imaging and adjust tip depth accordingly.
If you take one thing away from today — choose between Shurink and Ultherapy based on the depth of your sagging, not the price tag.
In my next post, I'll break down "Shurink 3 sessions over 3 weeks vs. a single Ultherapy session 6 months apart — what happens when the same person tries both." I'll walk through how Collagen accumulation translates into SMAS Layer stabilization using real cases. This has been Dr. Wi Young-jin.
