Skin Boosters or Lifting in Gangnam: Match Your Concern

“Idol treatment” is a name people use for two different categories: skin boosters, which work on hydration and surface texture, and lifting, which works on sagging in the deeper layers. The useful first step is deciding which category your own concern belongs to, then checking the specific options and recovery timing for that category in a consultation. UH CELL Clinic Gangnam runs both categories, inside the UH FLAT SIGNATURE Gangnam hotel building.

Hello, I am Dr. Kim Yeon-jin, Chief Physician at UH CELL Clinic Gangnam. If you are asking about the “skin booster and lifting combination that idols get,” I would first ask you to picture the exact moment your skin bothers you. Is it your makeup lifting off by midday, or your jawline looking less defined in photos? The same phrase, “idol treatment,” points to very different procedures depending on which one you mean.

Two Different Questions Hide Under One Name

A skin booster is an injectable that works inside the skin to change its quality. One common approach places hyaluronic acid in very small droplets into the dermis to improve hydration and smoothness. Another uses polynucleotides, a compound derived from salmon DNA, injected for similar surface goals. Skinvive, for example, is a hyaluronic acid micro-droplet injection that AbbVie’s Allergan Aesthetics division reported in 2023 had received U.S. FDA approval specifically for improving cheek skin smoothness in adults aged 21 and older.

Lifting uses energy, ultrasound or radiofrequency, delivered to deeper layers of the skin to address sagging and firmness. Merz Aesthetics, which makes Ultherapy, states in its own materials that the device’s U.S. FDA clearance covers eyebrow lifting, lifting skin on the neck and under the chin, and improving lines on the chest area. That clearance is defined by body area, which means a lifting device is not a single treatment for “the whole face” but something matched to a specific region and goal.

The evidence behind the two categories also differs in kind. For polynucleotide skin boosters, Smaragda Lampridou and colleagues published a systematic review in the Journal of Cosmetic Dermatology in 2024 covering nine studies that met their criteria, totaling 219 patients. They rated the overall study quality as low to moderate and noted that injection sites and technique varied between studies. That is why I describe a skin booster by the concern it targets rather than by a percentage of improvement: the research supports a general direction, not a precise number.

Matching Your Concern to a Treatment Category

If this is what you notice	Category to check first	Gangnam options we offer	What we confirm in consultation
Makeup lifts off and skin looks dry	Skin booster (hydration, texture)	Skinvive, Rejuran Healer	Whether the dryness is a skin condition or a habit/skincare issue
Visible pores and uneven texture	Skin booster + radiofrequency microneedling	Potenza, Rejuran Healer	Depth and extent of pores or scarring
Jawline and under-cheek area look less defined	Lifting (ultrasound)	Ultherapy, Sofwave	Where the sagging is and the thickness of skin and fat
Skin feels thinner with overall loss of firmness	Lifting (radiofrequency)	Thermage FLX, OligioX	Extent of the firmness loss and the degree of change you want
Volume loss in certain areas is also a concern	Skin booster (collagen-stimulating type)	Juvelook	Where the volume loss is and whether lifting should be combined

Potenza delivers radiofrequency energy to either the dermis or the epidermis, using a non-insulated or insulated mode depending on the goal, which is why we sometimes review it alongside a skin booster for patients whose main concern is surface texture such as pores or scarring.

Diagnosis Changes the Plan, Not the Treatment Name

Even on the same face, the cheekbone area, the cheek itself, and the jawline each differ in skin thickness, fat distribution, and degree of sagging. Following “the treatment an idol received” without adjustment can mean energy or product goes into an area that was not actually your concern. That is the reason we start from an individual skin diagnosis rather than from a treatment name, and design the plan from there.

It is also worth knowing that which specific clinic a public figure visits is generally not something we can confirm. Medical institutions cannot disclose patient information learned in the course of treatment, and the use of patient testimonials in medical advertising is restricted here as well. Rather than searching for a clinic by a celebrity’s name, checking whether a clinic has the right option for your own concern and whether recovery fits your schedule is the more useful standard.

If You’re Visiting Seoul on a Short Trip

If you are coming to Seoul for a few days specifically for treatment, preparing the following before your consultation lets us spend more of that time on diagnosis and planning:

1. The one or two areas that concern you most, with a photo that shows the concern clearly
2. Your arrival and departure dates, and whether you have photos or an important event right after returning home
3. The names and approximate dates of any skin procedures you have had in the past year
4. Current medications and any allergies
5. How much change you are hoping for, a natural refresh or a more visible difference

The shorter your stay, the more downtime and swelling schedules matter to which treatment makes sense. Because individual recovery speed varies, sharing your itinerary with us lets us discuss treatment order and scope together.

Where Treatment and Recovery Meet in Gangnam

Our Gangnam clinic is inside the UH FLAT SIGNATURE Gangnam hotel building, on the 2nd and 3rd floors of the WD building at Teheran-ro 8-gil 13, Gangnam-gu, Seoul. UH CELL operates as an on-site amenity within an UHC group hotel rather than as a separately located partner clinic, so staying at the same group hotel places lodging, treatment, and recovery care along one path. Treatment takes place in a private room.

Guests staying at an UHC group hotel can choose one complimentary option, either a 30-minute oxygen chamber session or a vitamin IV drip. If you use both, the vitamin IV drip is priced at 55,000 KRW. Full conditions are available on our promotion page.

Our Gangnam clinic has interpreting staff on-site for Japanese, Chinese, and English. I completed my graduate studies at Seoul National University and trained at Seoul National University Hospital. I serve as Allergan faculty for Juvederm and Botox, and as a Key Doctor for Potenza and Ultherapy Z. I am also a lecturer with the Korean Society of Clinical Cosmetic Medicine and a full member of the Korean Society for Aesthetic Plastic and Laser Medicine.

FAQ

Can you tell me which clinic a specific celebrity visits?
We cannot disclose whether a particular individual has visited, because medical institutions cannot reveal patient information learned during treatment. If you describe or show us the skin change you want, we can tell you which category of treatment fits that concern based on a diagnosis.

Do I need both a skin booster and a lifting treatment?
Not necessarily. If your concern is mainly texture and hydration, a skin booster alone may be enough to review; if sagging is the main concern, lifting alone may be the starting point. When both concerns are present, we discuss combining them, and the scope is still set according to your stay and your skin condition.

How reliable is the evidence for skin boosters?
It depends on the specific product. Some, like Skinvive, have a regulatory approval tied to a defined area and purpose in another market. Others, like polynucleotide skin boosters, are supported by research that trends positive but varies in study quality and method. Because individual skin response varies, we do not promise a specific numeric outcome, and we review the treatment’s goal and its limits together during consultation.

Can I be consulted in English if I don’t speak Korean?
Yes. Our Gangnam clinic has interpreting staff available in Japanese, Chinese, and English. Let us know your preferred language when you book.

If the “idol treatment” question brought you here, bring a photo of the area that concerns you most along with your Seoul schedule when you book a consultation at our Gangnam clinic. Hotel stay and recovery care conditions are also available on our promotion page.
