Shurink Universe (Classys) is a HIFU (high-intensity focused ultrasound) device that heats tiny points beneath the skin, reaching as deep as the SMAS layer, with the aim of firming the lower face without an incision. At ENTER Plastic Surgery in Seoul, a face session takes 20 to 40 minutes under numbing cream, is priced by shot count, and allows a flight home the same day.
Is it for you?
Who Shurink Universe suits
Focused ultrasound works on tissue that has started to loosen but still has its volume. The people it fits are noticing a softer jawline, the first heaviness beside the mouth or a slight drop under the chin, and they want a change measured in months with no stitches. It also fits travelers, because a session leaves no wound to care for and the clinic allows a same-day flight.
The limits are just as clear. Heat can encourage new collagen, yet it cannot move a cheek pad that has slid down by centimeters or remove a fold of hanging neck skin, and it adds no volume where the face has hollowed. In those situations a surgical lift or a filler conversation is the more useful starting point, and a session would mainly cost time and money.
Usually a good fit
- Early laxity along the jawline or under the chin
- Mild heaviness beside the mouth or on the lower cheeks
- Wanting firmer skin with no incision or stitches
- Short trips that need a same-day flight home
- Eye-area crepiness suited to a small 100-shot pass
We may suggest waiting
- Deep sagging or hanging neck skin needing surgery
- Hollow cheeks or temples where volume is the issue
- Active acne, infection or an open wound on the area
- Pregnancy, or a metal implant or device in the area
- Wanting the result of a facelift from one session
How it works
How Shurink Universe heats the deeper layers
Ultrasound energy passes through the outer skin and converges at a fixed depth, where it creates small points of heat. Each point shrinks the collagen around it and starts a slow repair process, so firmness builds over the following weeks. The handpiece works with different cartridges, which lets one session place energy at more than one depth: closer to the dermis for skin texture and deeper toward the SMAS, the fibrous sheet that the surgeon tightens in a facelift.
A shot is one pulse delivered along a line. Larger areas take more shots, which is why the face is sold in 300, 600 and 900-shot tiers and the delicate skin around the eyes has its own 100-shot line. The tier is matched to the area covered and how loose the tissue is.
Research on HIFU is encouraging, though modest in size. A meta-analysis of 17 studies with 477 patients found moderate objective improvement and satisfaction, an average pain score of 4.2 out of 10, and little long-term follow-up (Ayatollahi, 2020). Those studies used a range of HIFU devices, so the figures describe the technology in general and are not specific to Shurink Universe. A prospective study of another focused-ultrasound device likewise judged it suitable for selected patients with mild laxity and no volume loss (Friedman, 2020).
Laxity and area check
At consultationThe jawline, cheeks, under-chin and eye area are examined to see where tissue has loosened and which shot tier covers that area.
Numbing the treated zones
The skin is cleansed and numbing cream is applied so that the heat pulses are easier to tolerate.
Pulses along set lines
20–40 minutesUltrasound gel is spread and the handpiece delivers shots in rows across each zone, with the cartridge depth changed for deeper or more superficial passes.
Cleanup and same-day travel
Same dayThe gel is wiped off, any redness is calmed, and you can leave for the airport the same day following the clinic guidance.

Prices
Shurink Universe price list in South Korea
Every Shurink Universe line is priced per shot package, so the number on the card already reflects how much of the face is covered. A first session on the lower face and jawline starts from ₩400,000 for 300 shots, and the 600 and 900-shot tiers extend coverage to more of the cheeks, chin and neck. The eye area is a separate 100-shot line that can be booked alone or added to a face tier.
Body Shurink uses its own larger packages of 800, 1,600 and 2,400 shots. All prices are listed before VAT (10% VAT is added at payment). If you want numbing, soothing care or a second area itemized, ask for a written quote that lists each line.
Prices exclude VAT (10% VAT is added at payment).
Recovery
Aftercare following Shurink Universe
Mild redness and warmth fade within hours. Light cleansing and normal travel are fine, and the clinic allows a flight home the same day.
Swelling can last three to seven days depending on the person. Sleeping with the head slightly raised and avoiding saunas helps it settle.
A dull, deep ache along the jawline or cheekbones can last one to two weeks. It is tender to press rather than painful at rest.
Avoid strong facial massage or pressure-based facials for two to four weeks so the treated tissue is not disturbed while it remodels.
Safety
Risks of Shurink Universe and other HIFU
Focused ultrasound is non-invasive, but the heat it delivers is real, and complications are described in the literature. A case series and review found that serious adverse events after focused ultrasound are uncommon yet possible and probably underreported (Friedmann, 2017).
- Redness, swelling and tenderness, and a deep ache over bony areas that can last up to two weeks.
- Raised lines, welts or bruising where rows of shots were placed.
- Surface burns or blisters if energy collects too close to the skin.
- Temporary numbness, tingling or weakness of a facial nerve branch, with a lopsided smile in rare cases.
- A hollowed look from loss of fat in thin faces, which has been reported after deep passes.
Contact the clinic straight away if you notice blistering, a burn mark, spreading pain or any change in how your face moves.

FAQ
Shurink Universe questions
How many Shurink Universe shots does a face need?
There is no single number for every face. The clinic offers 300, 600 and 900-shot tiers, and the right one depends on how much of the lower face, cheeks, chin and neck is treated and how loose the tissue is. Smaller coverage suits 300 shots; wider coverage takes a higher tier.
Is Shurink around the eyes priced separately?
Yes. The eye area has its own 100-shot line at ₩200,000 + VAT, separate from the face tiers. It can be booked alone or added to a face session, and the eye cartridge places energy more superficially because the skin there is thin.
Is Shurink Universe the same as Ultherapy?
No. Both use focused ultrasound to heat deeper layers, but they are different devices. Ultherapy shows an ultrasound image of the tissue during treatment, and the clinic's guidance gives it a longer interval between sessions. Shurink Universe sessions are shorter and can be repeated within months.
Does Shurink Universe hurt?
Each pulse feels like a brief, deep prick of heat, strongest over the jawbone and cheekbones. Numbing cream is applied first. Across HIFU studies the average pain score was 4.2 out of 10, so expect discomfort that is noticeable but short, pulse by pulse (Ayatollahi, 2020).
Can I fly home on the same day as Shurink Universe?
Yes. The clinic's guidance allows a flight home on the treatment day, because there is no wound or dressing. Swelling can build over the next few days in some people, so a window seat with a cold drink and a pillow for the neck is more comfortable than a full schedule.
What should I avoid after a Shurink Universe session?
Skip strong facial massage, gua sha and pressure-based facials for two to four weeks. Saunas, hot baths and hard workouts are worth postponing while swelling lasts. Gentle cleansing, sunscreen and normal makeup are fine, and any blistering or a burn mark should be reported to the clinic at once.
Who will I see for Shurink Universe at ENTER Plastic Surgery?
ENTER Plastic Surgery is a plastic surgery clinic led by Dr. Jang Jin-woo, a Korean board-certified plastic surgeon trained at Kyung Hee University Medical Center. If you want to know who will plan and carry out your session on the day, ask when you book and the clinic will tell you.
Does the Shurink Universe price include VAT?
No. Each shot package is listed before VAT, and 10% VAT is added at payment. Numbing cream or soothing care after the session may be itemized differently, so request a written quote that shows every line before you pay, especially if you plan to combine face and eye-area shots.
How do I contact the clinic from abroad?
Send the form on this page or message us on WhatsApp, and we will get back to you as soon as possible. English-speaking staff are available at the clinic. Tell us which areas bother you and your travel dates, so the shot tier and timing can be planned together.
Do I need a deposit, and what happens if I cancel?
Deposit and cancellation terms depend on the booking, so ask for them in writing before you pay. Because Shurink Universe allows a same-day flight, the appointment can sit on any clinic day of your trip, which leaves room to move it if your plans change.
Can Shurink Universe replace a facelift?
Not for marked sagging. Focused ultrasound suits early laxity and builds firmness gradually, while a facelift repositions tissue and removes excess skin. If jowls hang well below the jawline or the neck has loose folds, the surgical options are the realistic comparison, and a session would add little.
How does focused ultrasound firm the skin?
It heats small points at a set depth, which contracts existing collagen and starts a repair process that lays down new collagen over weeks. Reviews describe this neocollagenesis and tissue remodeling as the mechanism, while noting that complications can occur even with a minimally invasive treatment (Welc, 2025).
