The choice between InMode and Shrink Universe depends on whether your concern is fat or sagging. If both fat under the chin and sagging are concerns, InMode is a candidate to consider, and if the goal is mainly to improve sagging, Shrink Universe is. Since it is hard to judge the effect of either from a single session, deciding after measuring the skin's condition is the recommended approach.

How Do the Two Treatments Differ in Principle?
InMode is a device that uses bipolar radiofrequency (RF) together with vacuum suction. Localized fat reduction and improved skin firmness proceed at the same time. The InMode FX/Forma owned by Repic Clinic in Gangnam is an FDA-approved device and checks the epidermal temperature 1,000 times per second.
Shrink Universe is a device that uses high-intensity focused ultrasound (HIFU) to stimulate the dermis and the SMAS layer (fascia) to encourage lifting. It uses a variety of cartridges and, as a domestically made device, is described as relatively less painful.
Which Treatment Should You Consider First for Which Concern?
- InMode: When both fat under the chin and sagging are concerns
- Shrink Universe: When the goal is mainly to improve sagging, such as a sagging face line, double chin, nasolabial folds or neck wrinkles
For concerns like a double chin, where both treatments come up, the choice depends on whether the cause is fat or sagging. It is hard to tell the difference from the impression in the mirror alone. That is why diagnostic numbers become the basis for the decision.
How Do Pain, Recovery and Treatment Intervals Differ?
Downtime is short with InMode and almost none with Shrink Universe. Pain varies with the treatment area, the power setting and individual sensitivity, so please check this in advance at the consultation.
It is hard to judge the effect from one session, and the number of sessions is usually adjusted at intervals of 2 to 4 weeks. If you have an event to attend, the intervals have to be worked out backward from it, so it helps to share your schedule first.
In What Order Are Decisions Made at Repic Clinic in Gangnam?
Repic Clinic in Gangnam quantifies skin thickness, location of sagging, pores, pigmentation and facial proportions through dual diagnostics: Meta View (skin surface) and Mark-Vu (deep analysis). This data is used as the basis for treatment decisions, and the clinic's principle is not to perform treatment without diagnostics.
Diagnosis, consultation and treatment are handled directly by the doctors under a five-doctor system, and consultation coordinators do not lead treatment decisions. The clinic applies its "Design" series approach, in which the same treatment name is planned differently for each patient, and besides InMode and Shrink Universe it also has Ulthera, Thermage FLX, ONDA and others. It is located at B1 and 2nd floor, 318 Gangnam-daero, Gangnam-gu, Seoul.
Pre-Consultation Checklist

Frequently Asked Questions
Which is better, InMode or Shrink Universe?
It is a question of suitability rather than superiority. InMode addresses localized fat reduction and improved firmness together, while Shrink Universe focuses on improving sagging with HIFU. The suitable one is chosen after diagnosing fat distribution and the degree of sagging.
If I have both fat under the chin and sagging, which treatment should I consider?
InMode, which uses bipolar RF with vacuum suction, is classified as suitable for such cases, because fat reduction and improved skin firmness proceed at the same time. Whether it actually applies depends on the diagnostic result.
What is the principle behind Shrink Universe?
Shrink Universe is a device that uses high-intensity focused ultrasound (HIFU) to stimulate the dermis and SMAS layer and encourage lifting. It is aimed at improving a sagging face line, double chin, nasolabial folds and neck wrinkles, and downtime is almost none.
How many sessions, and at what intervals?
For both InMode and Shrink Universe, it is hard to judge the effect from a single session. The number of sessions is usually adjusted at intervals of 2 to 4 weeks and may vary with your skin condition and goals.
How do Ulthera and Shrink differ?
Both use HIFU, but the device characteristics differ. Ulthera is a U.S. FDA-approved device that allows ultrasound visualization and tends to act deeply and precisely on the SMAS layer. Shrink is a domestic device with a lower cost per shot and relatively less pain. For deep sagging, Ulthera may be reasonable, and for regular firmness maintenance, Shrink may be.
What is checked in the pre-treatment diagnosis?

These numbers are used to decide the type and number of treatments. You can find more details on the official page and through a consultation.
