How Much Does Shurink Universe Hurt? A Complete Guide to How It Works and Aftercare Precautions

Shurink Universe is performed after applying numbing cream, and you may feel heat or a prickling sensation deep in the skin at the moment the ultrasound converges.
A lifting device by Classys that focuses high-intensity focused ultrasound (HIFU) at set depths within the skin to create small thermal coagulation points. How much you feel varies by area, depth, and skin thickness, and you can return to daily activities immediately after treatment.
How Shurink Universe Works
With age, the fascia (SMAS) layer that supports the skin loosens and collagen and elastic fibers decrease, making the cheeks and jawline appear to sag. This device sends ultrasound energy down to that layer.
- Ultrasound focusing: Ultrasound is concentrated at a single point, generating heat at a set depth while causing little damage to the skin surface.
- Thermal coagulation points: The heated tissue contracts, followed by a process in which collagen is newly produced.
- Depth by cartridge: Facial cartridges come in 1.5mm, 2.0mm, 3.0mm, and 4.5mm, and are swapped to suit the area and skin thickness.
According to the manufacturer, this device delivers energy to the dermis, the fascia layer, and the subcutaneous fat layer. Even with the same device, the plan differs depending on which depths are used and how many shots are applied.
Ultra F vs. Ultra Booster
| Category | Ultra F | Ultra Booster |
|---|---|---|
| Cartridge shape | Linear type | Round pen type |
| Best-suited areas | Broad surfaces such as the cheeks and jawline | Narrow, curved areas such as nasolabial folds, around the eyes, and cheekbones |
| Facial depths | 1.5mm, 2.0mm, 3.0mm, 4.5mm | 1.5mm, 3.0mm, 4.5mm |
| Mode | Normal (dot), MP | Normal (dot), MP |
| Options at our Suwon clinic | 100 shots, 500 shots | 100 shots |
Normal mode delivers energy in dots to concentrate heat at a set layer, while MP mode heats a wider area continuously. Because MP mode can cover broad areas quickly, it is used to shorten treatment time.
Sensation and pain during treatment
- Heat: As the ultrasound focuses, you may feel heat or a prickling sensation beneath the skin.
- Dull ache: Areas close to the bone, such as the jawline and cheekbones, may feel achy.
- Anesthesia: We begin after applying numbing cream to reduce discomfort. If you feel significant discomfort during the treatment, please let us know right away.
The treatment takes about 1 hour in total and proceeds in this order: Personalized Consultation, Self-Cleansing, Numbing Cream, Treatment, and Finishing Care.
Who this treatment suits
- Those concerned about their facial lines due to sagging cheeks and a less defined jawline
- Those concerned about firmness in small areas such as around the eyes, the mouth, and the nasolabial folds
- Those bothered by both a double chin and the line beneath the jaw
- Those who need to finish treatment quickly and return to daily life right away
Depending on your skin condition, we recommend a schedule of at least 3~5 sessions at 1-month intervals, and results last approximately 3~6 months.
If you are worried about your cheeks looking hollow
If your cheeks already look hollow or the area below the cheekbones is sunken, using a lot of energy at deep layers may make the face look as if it has lost even more volume. For such faces, we determine deep cartridge use and the number of shots separately, starting the examination by assessing volume and skin thickness.

Precautions on the day of treatment
- You can wash your face and wear makeup right away; use a gentle cleanser.
- Do not rub the treated area hard or touch it often.
What to Avoid for One Week
- For the first 3 days, wash your face with lukewarm water only.
- For about 7 days, avoid heavy drinking, saunas and jjimjilbang (Korean bathhouses), hot baths, and strenuous exercise.
Post-Treatment Care
- Your skin may become dry, so apply moisturizer often and use sunscreen when going out.
- We recommend taking antioxidants such as vitamin C.
- Heat, tingling, swelling, redness, a burning sensation, dryness, and itching usually subside soon.
Rarely, the cheeks may look hollow, or a burn may occur on the epidermis if the cartridge does not make even contact with the skin. Please contact us right away if blisters form, if redness and pain worsen day by day, or if numbness persists. Please let us know before treatment if you are pregnant or breastfeeding, have dermatitis, wounds, or severe acne in the treatment area, have recently received fillers or thread lifting, or have metal implants in your face.
