Shurink Universe: Seven Cartridges, Two Handpieces
Second-generation focused ultrasound, concentrating energy on the SMAS so tissue contracts and collagen rebuilds. What distinguishes it is range: seven cartridges across two handpieces.

Quick Answer
Is Shurink as good as Ultherapy?
Different, not lesser. The right question is which suits your face.
In Brief
Same principle, different instrument.
Shurink Universe is a Korean HIFU platform made by CLASSYS. Like Ultherapy it delivers focused ultrasound to create small thermal points beneath the skin, prompting collagen to rebuild. The practical differences are that it uses preset cartridge depths rather than real-time imaging, that it is generally more comfortable, and that it delivers more points per session at a lower cost per point. Ultherapy tends to hold results longer. Neither fact makes one the better choice in the abstract.

The Cartridges
Seven Depths, Two Handpieces
A single HIFU setting across a whole face treats the jaw and the eye area the same way, which is why some clinics avoid the eyes altogether. Seven cartridges is what makes a per-area plan possible.
| Handpiece | Cartridge | Depth | Typically used for |
|---|---|---|---|
| UltraF (linear) | Derma | 1.5mm | Skin layer, fine lines |
| I Shurink | 2.0mm | Around the eyes and thinner skin | |
| Celup | 3.0mm | Cheeks and mid-face | |
| Linup | 4.5mm | SMAS layer, jawline and neck | |
| Ultra Booster (pen) | Derma Booster | 1.5mm | Curved and narrow areas |
| Celup Booster | 2.0mm | Eye area and around the mouth | |
| Linup Booster | 3.0mm | Nasolabial folds and contours |
The pen-type handpiece delivers energy in a circular pattern rather than a line, so it can follow a curve. Your doctor will tell you which cartridges your treatment uses, and why those.
Understanding It
What the Cartridge Depths Actually Do
Focused ultrasound converges energy at a set depth, leaving the skin above it undisturbed. Shurink Universe covers a range of depths using different cartridges: the shallower ones work in the dermis, where skin quality and fine laxity live, and the deeper cartridge reaches the SMAS. The structural layer a surgeon works on during a facelift.
Selecting between them is the whole treatment. A face that has lost firmness in the skin needs different depths from a face where the support layer beneath has softened, and most faces need more than one. Coverage matters too: results depend on how thoroughly the area is treated, not simply on which device was used.
Change is gradual. Collagen remodelling peaks over the following months rather than appearing on the day, and results are generally maintained with repeat treatment at a sensible interval, not being permanent.

Honest Comparison
Where It Sits Against Ultherapy
Ultherapy uses real-time imaging, so the doctor can see the tissue layers while treating. Shurink relies on anatomical landmarks and preset depths instead, which puts more weight on the experience of the person holding the handpiece. That’s a real difference and worth knowing before you choose.
In exchange, Shurink is typically more comfortable, delivers more points per session, and costs less. For someone with early laxity, or someone treating maintenance, not established sagging, that trade is often the sensible one. For a face with significant descent, the deeper and more precisely placed option may do more.
We run both. That’s the point of having a roster rather than a flagship: the recommendation can follow your face instead of following whichever machine the clinic happens to own.
Candidacy
Who It May Be For
It suits people beginning to notice early loss of firmness, people who want the lower face and jawline refined without incisions or recovery, and people trying HIFU for the first time who would rather start gently.
It also suits visitors well. There is no real downtime, so it fits into a short trip to Seoul without costing you days.
It suits less well where laxity is advanced, where skin excess is genuinely surgical, or where the concern is volume, not support. A hollow face tightened is still a hollow face.
The Visit
What to Expect
Your doctor assesses where firmness has been lost and plans depth and coverage accordingly, checking for anything that would make treatment unwise. Recent procedures and current medication should be mentioned at this point.
The area is cleansed and mapped, and numbing cream is applied for around fifteen minutes, adjusted to your sensitivity. Treatment follows cartridge by cartridge across the planned area.
Most people describe brief heat at each point. There’s no downtime. Mild redness typically settles within a couple of hours, and ordinary activity resumes immediately.

How It Works
Assess. Numb. Treat.
The first step decides the rest. Seven cartridges are only useful if someone works out which ones your face needs.
01
First, we decide which cartridges your face needs
Skin thickness, where the laxity sits, and whether the eye area is involved. That decides which of the seven cartridges are used and at what depths. If focused ultrasound isn’t the right answer for your face, we’ll say so rather than treat anyway.

02
Then, numbing, and treatment area by area
Numbing cream is applied first. The linear handpiece covers broad areas; the pen-type follows curves around the eyes and mouth where a straight cartridge can’t sit. Bidirectional scanning makes the pass about 2.5 times faster than the previous generation.

03
Then, collagen rebuilds over two to three months
You can wash your face and wear light makeup immediately. There is an immediate tightening, but that is tissue response rather than the result. Collagen rebuilds over the following months, and the effect accumulates across two or three sessions spaced three to four weeks apart.

Key Points
What to Take Away
- Shurink Universe is second-generation HIFU, concentrating energy on the SMAS layer to contract tissue and prompt collagen.
- Seven cartridges across two handpieces: a linear UltraF for broad areas and a pen-type Ultra Booster for curves.
- UltraF works at 1.5, 2.0, 3.0 and 4.5mm; the pen-type at 1.5, 2.0 and 3.0mm.
- The pen-type delivers energy in a circular pattern, so it can treat around the eyes and other curved areas.
- Bidirectional scanning makes it about 2.5 times faster than the previous generation, so the appointment is shorter.
- Two modes are available in one handpiece: dot and linear, chosen for the area being treated.
- Onlif recommends 2 to 3 sessions spaced 3 to 4 weeks apart.
- You can wash your face and wear light makeup immediately afterwards.
- Numbing is applied before treatment, and cooling is used during it. Comfort still varies between people.
FAQ
Questions People Ask
Numbing is applied before treatment and the device uses cooling during it, so most people find it manageable. Pain varies between individuals, and the deeper 4.5mm cartridge is felt more than the shallower ones. Tell us if you’re sensitive and the settings can be adjusted.
Yes. You can wash your face and wear light makeup immediately. There’s usually no bruising or swelling.
Onlif recommends two to three, spaced three to four weeks apart. This varies with skin type and how far the change has progressed, and your doctor will give you a number at consultation.
Yes, with the pen-type handpiece. It delivers energy in a circular pattern rather than a straight line, which lets it follow the curve of the orbital area. A linear cartridge can’t sit properly there.
This is the second generation. The practical differences are the pen-type handpiece for curved areas, bidirectional scanning that’s about 2.5 times faster, and a wider set of cartridges. The underlying technology is the same focused ultrasound.
There is an immediate tightening, but the collagen response builds over the following two to three months and accumulates across the course. We compare photographs rather than judging on the day.
