1. What is Shrink?
Shrink (Shurink) is a non-surgical lifting treatment that uses MMFU (Micro & Macro Focused Ultrasound) technology.
Compared to traditional HIFU devices, it delivers a denser, more precise pattern of ultrasound energy into the dermal and SMAS layers — driving collagen regeneration and lifting. Discomfort is comparatively low while the lifting effect remains strong.
MMFU Technology — Key Features
Densely Packed Shots
A denser shot pattern than conventional HIFU produces more uniform, effective lifting.
Multiple Treatment Depths
Cartridges of various depths (1.5 mm, 3.0 mm, 4.5 mm) allow precise energy delivery matched to each treatment area.
Less Discomfort
Micro-focused energy is concentrated exactly at target points without spreading, sparing surrounding tissue and reducing pain.
2. Shrink vs. Ulthera
Both Shrink and Ulthera are ultrasound-based lifting treatments, but there are key technical differences.
| Category | Shrink | Ulthera |
|---|---|---|
| Technology | MMFU (Micro & Macro Focused Ultrasound) | HIFU (High-Intensity Focused Ultrasound) |
| Shot Density | More densely spaced | Comparatively wider spacing |
| Discomfort | Comparatively lower | Comparatively higher |
| Depth Options | Multiple depth cartridges | 1.5 / 3.0 / 4.5 mm |
| Regulatory | Cleared by Korea MFDS | Cleared by US FDA |
| Treatment Time | 20–40 min | 30–60 min |
Which one is better for me?
Both are effective lifting treatments — which is best depends on your skin condition and the result you want. We'll recommend the right option at your consultation.

4. Expected Results
Improved Elasticity
Collagen regeneration leads to firmer, more elastic skin.
Reduced Fine Lines
Fine lines around the eyes and forehead naturally diminish.
V-Line Effect
A more defined jawline produces a slimmer, more youthful V-line.
5. Aftercare
Immediate Return to Daily Life
Normal activities resume right after treatment. Some mild redness or swelling may appear and typically clears within hours.
Hydration Matters
Skin may feel temporarily dry — keep it well hydrated.
Sun Protection Is Essential
Apply sunscreen thoroughly and avoid saunas and jjimjilbangs for 1 week.
When Results Appear
You may feel some lifting immediately after treatment; the full effect develops over 1–3 months as collagen regenerates.
Maintenance Schedule
To sustain the lifting effect of Shrink, maintenance sessions every 6 months to 1 year are recommended.
