Shurink Universe is a high-intensity focused ultrasound (HIFU) lifting device made by Classys in Korea, used to firm and lift facial skin without surgery. It delivers micro-focused ultrasound energy to precise depths beneath the surface, creating tiny thermal coagulation points that trigger the body’s own collagen-building response. Because the energy is focused rather than spread across the surface, the skin’s outer layer is spared while deeper structures are treated.
Its defining feature is the ability to reach the SMAS (superficial musculoaponeurotic system) at around 4.5mm, the same structural layer a surgeon tightens during a facelift. Treating this layer with focused ultrasound is what gives HIFU a genuine lifting effect rather than only surface tightening. Shallower 3.0mm and 1.5mm cartridges target the deep and mid dermis for firmness and texture, so a single plan can address multiple depths.
At Reberry Clinic, Shurink Universe is performed at our Gangnam (Seoul) location by Dr. Yoongon Ryu, who maps the treatment to your facial anatomy and skin laxity. International patients receive full English-language support, and Gangnam-daero is roughly a 2-minute walk from Gangnam Station exit 10, making it easy to reach in Seoul, Korea.
Shurink Universe uses micro-focused ultrasound: sound waves are concentrated to a focal point below the skin, where they rapidly raise tissue temperature to roughly 60 to 70°C. At that heat, collagen fibres denature and immediately contract, and over the following weeks fibroblasts lay down new collagen as the treated points heal, a process called neocollagenesis. The result builds gradually rather than instantly. Different transducer cartridges place these thermal points at fixed depths, typically 4.5mm for the SMAS, 3.0mm for the deep dermis, and 1.5mm for the superficial dermis, so the clinic’s doctors can stack depths to both lift and refine. Because the ultrasound bypasses the epidermis, there is no open wound and most people return to normal activity the same day. This ultrasound mechanism is distinct from radiofrequency devices such as Thermage FLX, which heat tissue with monopolar RF instead of focused sound.

Dr. Yoongon Ryu grades your skin laxity and maps 3 depth zones (1.5, 3.0, 4.5mm) to match your face.
The treatment area is cleansed and gridded so ultrasound shots are placed evenly, usually across 2 to 3 facial zones.
The device fires hundreds of focal points, often 300 to 500+ shots total, heating each to roughly 60 to 70°C at set depths.
The 4.5mm cartridge reaches the SMAS to create the lift, while 3.0 and 1.5mm passes firm the dermis for texture.
Over the next 2 to 3 months, new collagen forms at the treated points, so the lifting effect builds progressively.
See representative outcomes from Reberry Clinic. Results build gradually and vary by individual; your plan is assessed at consultation.
Dr. Yoongon Ryu assesses your laxity and skin thickness, then plans depths and shot count, explaining everything in English at our Gangnam location.
After cleansing and numbing cream, the session usually takes about 20 to 40 minutes depending on how many facial zones are treated.
Most people feel warmth and brief tingling during shots and can return to normal activities the same day, with only occasional mild redness.
Some tightening may be felt early, but the lift builds over 2 to 3 months as new collagen forms at the treated points.
Results often last around a year and vary per person; gentle skincare and sun protection help, and a maintenance session keeps firmness over time.

Shurink Universe is performed at our Gangnam (Seoul) location by Dr. Yoongon Ryu, on Gangnam-daero about a 2-minute walk from Gangnam Station exit 10. International patients receive English-language consultation and aftercare, so the whole visit is easy to navigate even on a short trip to Seoul, Korea.
Most people feel warmth and a brief tingling or prickling sensation with each ultrasound shot, especially over bonier areas, but it is generally well tolerated. Numbing cream is applied beforehand to keep you comfortable. Sensation eases immediately after each pass, and the clinic’s doctors adjust settings if any zone feels too intense.
Shurink Universe has little to no downtime because the ultrasound bypasses the skin surface. You may notice mild redness, slight swelling, or tenderness for a few hours to a day, and occasionally small areas feel tender when pressed. Most people go straight back to work, travel, or sightseeing the same day.
Some early tightening may be felt within days, but the real lift builds gradually over 2 to 3 months as fibroblasts form new collagen at the treated points. Results continue to refine during this window, which is why the effect looks natural rather than sudden. Your doctor reviews progress at follow-up.
Results often last around a year, though this varies with age, skin quality, and lifestyle since ongoing ageing continues. Shurink Universe firms and lifts but is not a one-time fix, so many patients schedule a maintenance session to sustain the effect. Sun protection and good skincare help results hold longer.
Many patients see a meaningful effect from a single well-planned session, since HIFU works by stimulating collagen over months. Depending on your laxity, the clinic’s doctors may suggest a repeat around the 6 to 12 month mark, or combining depths in one visit. Your plan is set at consultation, not a fixed package.
Shurink Universe uses focused ultrasound to reach the SMAS at set depths for lifting, while Thermage uses monopolar radiofrequency to heat a broader volume of the dermis for overall tightening. Many people combine them for lift plus firmness. You can compare on our Thermage FLX page.
Yes, Shurink Universe pairs well with skin-quality treatments because it works at a structural level. Many patients add a Rejuran Healer or skin-booster session for texture and glow, or RF for extra firming. The clinic’s doctors sequence treatments so the skin is not over-stressed, planning intervals at your consultation.
HIFU is widely used and generally considered safe when a trained doctor sets the correct depth and energy for your skin. Side effects are usually mild and temporary, such as redness, swelling, or brief tenderness. A consultation screens for contraindications like implants or active infection so treatment is planned appropriately for you.
Adults with mild to moderate laxity along the jawline, lower face, or under-chin are typical candidates, especially those wanting firming without surgery. Very heavy sagging may need a surgical approach instead. A consultation confirms whether HIFU suits your skin, or whether a combined lifting plan works better.
Common effects are temporary redness, mild swelling, and tenderness that settle within hours to a day or two. Occasionally small bruises or numbness appear and resolve on their own. Serious effects are rare when performed correctly. Your doctor reviews your skin and medical history to keep risks low before treatment.
Aftercare is simple: keep skin hydrated, avoid harsh actives and heat like saunas for a couple of days, and use daily sunscreen. A gentle skin care routine supports collagen remodelling in the weeks after. Avoid vigorous facial massage briefly, and your doctor gives tailored guidance at your visit.
Yes, the jawline and lower face are among the areas that respond well, since HIFU can reach the SMAS to lift and define this region. Studies note the jawline improves notably after treatment. For submental fullness, your doctor may combine HIFU with other approaches. Individual results depend on skin laxity and volume.
Cost depends on how many facial zones are treated, the number of shots, and whether depths or treatments are combined, so it is set at consultation rather than a fixed price. The clinic’s doctors explain your plan and cost transparently in English. You can start on our face-lift page.
A single day is often enough, since the session takes about 20 to 40 minutes with little to no downtime. Many international patients arrive, treat, and continue sightseeing the same day. If combining treatments, 1 to 2 days gives room for consultation and a short review with your English-speaking team.
Yes, flying within a day is generally fine because Shurink Universe is non-invasive with no open wounds. Cabin air is drying, so moisturise and protect treated skin from sun. If you notice mild redness or tenderness, it usually settles quickly, and your doctor advises on anything specific before you travel.
Because HIFU results build over 2 to 3 months, much of the review can be done remotely, and Reberry Clinic offers English-language check-ins between visits. Many patients complete Shurink Universe in one trip and monitor progress from home. Your treatment notes are kept on file so any return visit continues seamlessly.
