Bad Thermage Side Effects: Rare, but Some Should Skip It
Bad Thermage side effects like burns, dents and dark marks are uncommon and tied to energy and selection. Who should skip it, from VOS Dermatology…
A Korean lift at VOS Dermatology uses one of six devices: Ultherapy Prime, Sofwave, Thermage FLX, Oligio XM, Double Tite and Revinas. Each one works at a different layer of the skin, and that depth is the main difference in Sofwave vs Ultherapy.
Dr. Hongseok Kim, a board-certified dermatologist with 21 years of experience, examines your skin and performs every treatment himself. Results vary from person to person; prices are listed on each treatment page.

View treatment: RevinasSagging, a double chin and crepey skin start in different layers of the face, so each needs a different device. Find your concern below to see which treatments are usually used.
The line from chin to ear is less sharp than it was. Sagging here usually starts in the deeper support layer (SMAS) and the fascia.
A double chin that shows in photos and side views, often with looser skin under the jaw.
Thin neck skin that creases and has lost some spring.
Skin that feels thinner, drier or less firm, with fine crinkly lines — before real sagging sets in.
Hooding over the eyelid and a brow that sits lower than before. VOS lists separate eye-area options: Ultherapy PRIME Eye and Thermage FLX Eye.
A starting point only — Dr. Kim confirms the match after examining your skin. Results vary from person to person.
Skin tightening works in the dermis; structural lifting reaches the SMAS beneath it. Knowing which layer is the problem explains most of the Sofwave vs Ultherapy question.

Ultherapy Prime Micro-focused ultrasound at 1.5, 3.0 and 4.5 mm — the deep dermis and the SMAS, checked on the DeepSEE image.
Depths are those stated by the clinic and the device makers. Your plan depends on your skin thickness, which Dr. Kim checks first.
Choose three things. You will see one or two treatments that usually fit — then Dr. Kim checks it against your skin.

At VOS, Dr. Kim does the consultation, the plan and every shot himself. This is how a treatment is planned.

Dr. Hongseok Kim — a board-certified dermatologist with 21 years in practice — consults, plans and performs every treatment himself. Nothing is handed to another doctor.

For Ultherapy Prime, Dr. Kim checks the depth on the DeepSEE image before each line and places the shots in an even 1 mm grid. The clinic uses authentic Ulthera devices and genuine tips.

Plans start from a skin analysis in a private 1:1 consultation room, so the areas, energy and shot count are set for your face rather than a fixed package.

Tightening the skin and lifting the support layer are different goals. When you have both, Dr. Kim combines devices that work at different depths — for example Ultherapy Prime with Sofwave.

Korea Thermage FLX procedure steps in order, who should wait, what decides the cost, and recovery, from Dr. Hongseok Kim of VOS Dermatology, Gangnam.
The worries I hear most from patients flying in — grouped by treatment. If yours is not here, ask me before you book.
Not necessarily, but the goal is different. On firm young skin, deep lifting has little to work on, so I usually think in terms of prevention — Double Tite, for example, is designed for skin that is only starting to lose firmness. I look at your skin before suggesting anything, and sometimes the honest answer is to wait.
Collagen-based change takes time: around 2–3 months for Ultherapy Prime and up to 2–6 months for Thermage FLX, while Sofwave usually shows from about a month. Thermage FLX and Double Tite often give some immediate tightening too. If you can, plan about three months ahead, and avoid the final week — after Ultherapy Prime, some tenderness can last up to 1–2 weeks.
Often, yes. Lifting works on firmness and support, while a hyaluronic acid booster such as Hilo Wave works on dryness and surface quality, so they can be discussed at the same consultation. The clinic also lists combination programs, such as Ultherapy Prime with Sofwave. What is sensible on the same day depends on your skin, and I decide that at consultation.
Focused ultrasound and radiofrequency work through heat in the dermis and deeper layers rather than by targeting pigment, so skin tone is generally less of a concern than with pigment lasers. Heat can still irritate sensitive skin, so I check your skin condition and adjust the settings. Pregnancy and some skin conditions need a consultation first.
Collagen builds gradually, so the fair moment to judge is after two to three months, not the next morning. Individual response differs and I can't promise a fixed result. Your treatment details are recorded in our Open Chart System, so if you message us later, I can review exactly what was done and talk you through the options.
Ultherapy Prime is designed to lift and tighten the support layers, not to remove volume. A slim face with little fat does need a careful plan, which is why I check the layers on the DeepSEE image before each line and choose the areas and depths for your face. If volume loss is the bigger issue, I will tell you honestly.
In many cases it can be planned, but I need to know what was done, where and when. I check the area on the ultrasound image and adjust the areas and depths around it. Bring any records you have to the consultation.
Yes — the clinic lists Ultherapy PRIME Eye separately, a treatment designed for the upper eyelids and brow, at 100, 300 or 400 shots. There is also a Signature Eye Rejuvenation Program that combines it with Sofwave and a skin booster. Which suits you depends on how much hooding and laxity you have.
Most people go straight back to their day. Mild redness or swelling can last 1–2 days, and some areas may feel tender for up to 1–2 weeks — noticeable when pressed, but usually not something that stops sightseeing or flying. It varies from person to person.
I advise avoiding saunas and strong active skincare for a few days. As a general principle, heat, intense exercise and alcohol increase blood flow and can make swelling linger, so it makes sense to keep the first day or two quiet. You will get aftercare notes for your skin right after the session.
Redness usually fades in about 20–30 minutes, so most people look presentable quickly. When to restart makeup and active skincare depends on how your skin reacts, so I tell you after the session rather than giving a single rule.
Fine lines in thin skin and a slightly lower brow are exactly what Sofwave is suited to, because it works at about 1.5 mm where fine lines form. The clinic's Signature Eye Rejuvenation Program uses 50 shots of Sofwave alongside Ultherapy PRIME Eye. Clear hooding of the upper lid usually needs a deeper treatment as well.
There is no fixed figure I can promise — how long the change lasts varies with your skin, age and lifestyle. Collagen keeps building for around three months after the session, so I usually review the result before talking about a repeat.
Thin skin with crinkly lines is one of the main reasons I choose Sofwave, and the surface is cooled during each pulse. If your skin is reactive or you have an active skin condition, I check it first and may adjust the plan or the timing.
Often it can be planned, but radiofrequency heats the dermis, so I need to know the product, the area and when it was injected. I examine the area and decide whether to treat around it or wait. Please bring any details you have.
Yes. Thermage FLX has a dedicated eye tip for the delicate eye area, and the clinic lists Thermage FLX Eye separately at 450 shots for eyelid firmness and fine lines around the eyes.
They do different jobs. Thermage FLX heats the deep dermis across the whole area for overall firmness, while Ultherapy Prime focuses energy in points down to the SMAS for structural lift. If your main issue is crepey, loosening skin, Thermage often comes first; if it is a sagging jawline, Ultherapy. Some people need both, and I plan the order at consultation.
The clinic lists Thermage FLX at 600 shots for the face, with the eye area as a separate 450-shot option. Whether 600 covers your concern depends on your face and skin, and I decide the tip and shot count after examining you. Results from a single session typically last around 1–1.5 years, varying by person.
It depends on the size of the area and how much tightening your skin needs. I examine your skin first and then choose between the two listed options: 300 shots at ₩800,000 or 600 shots at ₩1,500,000 (VAT added where applicable).
Mainly a skin-tightening treatment. It delivers radiofrequency heat from the surface layers to the deep dermis to improve elasticity, density and texture. Lifting the deeper support layer is a different goal, which is why I sometimes pair it with Ultherapy Prime.
Yes, they can be combined, because they work on different layers. Whether both are done on the same day or spaced out depends on your skin and schedule, and I plan that with you at consultation.
Oligio XM suits regular maintenance, but the right interval depends on your skin and how it responded. Rather than a fixed calendar, I review your skin at each visit and suggest the next session from there.
Double Tite is designed for the stage before a full lift — skin that is starting to feel slack, dry and finely lined. If the sagging already comes from the deeper support layer, a treatment such as Ultherapy Prime does that part. I tell you which stage I see at consultation.
The clinic's guidance is 2–3 treatments about a month apart. One session fits easily into a short trip because it is completed within 15 minutes; for a full course, people usually plan a return visit.
Improving dry skin and overall texture is one of the reasons people choose it, alongside firmness. How much your skin changes varies from person to person, and I look at the cause of the dryness before recommending it.
There is no listed downtime, and any redness usually fades within hours, with some tightening right away. As a general rule I still suggest leaving a few days' buffer before an important event, because every skin reacts a little differently.
After many procedures, tissue can become tense and stuck together, so further lifting gives less effect. Revinas sends pressure waves to the deep fascia to soften and relax that tissue rather than pull it, and it also supports lymphatic circulation. That is why I consider it for people whose earlier lifting did little.
It works by gradually strengthening the skin's foundation, so the clinic recommends 3–5 sessions about a month apart. Each session takes under 30 minutes, which makes it easy to add to repeat visits to Seoul.
Revinas is designed to relax tense tissue and improve circulation rather than to remove volume, aiming for a natural contour. Every face responds differently, so I look at your fat and skin thickness before recommending it.
They work by different mechanisms — pressure waves to the fascia versus focused ultrasound to the SMAS — so they can complement each other. Whether you need both, and in what order, I decide after examining your skin.
Treatment results, recovery and duration vary from person to person. This page is general information and does not replace an in-person consultation with a board-certified dermatologist.
