Hello, I am Yeon-jin Kim, the Representative Director of UH CELL (formerly Dr. Petit Clinic Gangnam).
For those planning “Ultherapy,” the gold standard of lifting, the biggest hesitation often stems from the fear of “Cheek Hollows.”
Especially if you are preparing for a trip to Korea, I know all too well the feeling of staying up late searching through reviews, worrying, “What if my cheeks look more sunken after trying to get prettier?” Having experienced countless cases, I understand your concerns better than anyone.
Today, I want to talk about the Ultherapy x SKINVIVE synergy—a method that preserves the powerful lifting effect of Ultherapy while simultaneously capturing facial volume and vitality.
Why do cheek hollows occur after Ultherapy?
Ultherapy uses High-Intensity Focused Ultrasound (HIFU) to contract the SMAS layer, the deepest part of the skin. While it is excellent for tightening sagging tissue, for those with thin skin or less facial fat, the contraction of the fat layer can make the cheek area look sunken.
The dry air during flights to Korea and UV exposure during outdoor activities drop the skin’s hyaluronic acid levels. Performing a heat-based lifting treatment in this state can make the “Cheek Hollow” phenomenon even more prominent.
How SKINVIVE Acts as a “Shield” for Ultherapy

To reduce this risk, the solution I’ve chosen is SKINVIVE.
- The Dermal Buffer Effect: SKINVIVE injects micro-hyaluronic acid into the dermis, instantly increasing moisture density. When the fat layer contracts due to Ultherapy, the dermis acts like a firm sponge, visually smoothing out hollows and creating a seamless curve.

- A Catalyst for Collagen: When a moisture-rich environment is created around the thermal coagulation points made by Ultherapy, fibroblasts regenerate collagen much faster. It goes beyond a simple “pulling lift” to a “firming lift” where the skin itself becomes more elastic.

UH CELL’s Signature “Triple Regeneration” System
At UH CELL Gangnam, we go a step further. We recommend pairing the treatment with the Hyperbaric Oxygen Chamber (HBOT) and Megadose Vitamin C IV therapy immediately after the procedure.
Vitamin C is an essential nutrient for collagen synthesis, and high-pressure oxygen supplies energy to cells, reducing swelling and stabilizing skin texture rapidly. This is my medical philosophy—designed so you can return to your daily life in the best condition within the limited time of your trip to Korea.
Conclusion: Lifting is the perfect balance between “Pulling” and “Filling.”
If Ultherapy is like strongly shrinking the surface of a balloon to regain tension, SKINVIVE plays the role of healthily filling the volume and balance inside that balloon.
There is one more crucial fact: SKINVIVE acts as a dense “Hyaluronic Acid Buffer” within the skin. It not only alleviates the specific heat and dryness that follows energy-device treatments like Ultherapy but also acts as a medical safety device to lower the risk of burns.
Ultimately, the combination of these two treatments is not just a simple addition. It creates a synergy that maximizes results while minimizing risks.
