Thermage Gone Wrong? Burns, Dents, Cost

Worried your face could end up looking like the gone wrong Thermage side effects you've been reading about, with a blister on the jaw, a small dent in the cheek, or a face that looks thinner instead of tighter?

Serious problems are uncommon. Most people get redness, mild swelling and tenderness that settle within hours to a few days. Burns, blisters and small dents from fat loss are rare, and they usually trace back to too much heat in one spot, a tip that wasn't sitting flat, or a break in surface cooling.

Hello, I'm Dr. Sarang Lim, Head Doctor at Muse Clinic Myeongdong in Seoul, and a member of the Korean Academy of Aesthetic Plastic & Laser Medicine.

Duet Thermage and Ulthera are both on our menu, so our conversation can be about which kind of heat suits your face. You'll go through the consultation with an English interpreter, at no extra charge, who stays with you into the treatment, and then I plan and perform the treatment myself. The price list on our site is the same one Korean patients see; there's no foreigner markup.

If a previous treatment left you wary, send a front and a side photo in daylight on WhatsApp, list any filler or threads you've had in your cheeks or jaw, and ask whether your face is one where you'd hold back on heat.

What actually goes wrong with Thermage, and how often?

Thermage is monopolar radiofrequency. A treatment tip on the skin passes a current that turns into heat in the deeper skin and the fibrous layer beneath it, while the surface is cooled during each pulse. The heat makes existing collagen contract and prompts the skin to build new collagen over the following months. Almost everything that goes wrong is a heat problem.

The largest published series worth knowing is a retrospective review of more than 600 consecutive treatments in the Journal of Drugs in Dermatology (2006). Temporary side effects followed 2.7% of treatments. Redness and swelling usually lasted under 24 hours, a handful of people had swelling for up to a week, and the authors reported no lasting side effects.

The notable events were one slight cheek depression, a few small bumps and one superficial crust, all resolved within a week; three people had neck tenderness that lasted two to three weeks.

The bottom three rows are what most accounts of gone wrong Thermage side effects describe. They're the rare ones, and they share a cause. Darker patches after any skin injury, called post-inflammatory hyperpigmentation, tend to be more common and slower to fade in medium and darker skin tones, according to DermNet, so a small burn matters more for those skin types.

Why a burn or a dent happens

Three things decide whether heat stays where it belongs. The first is contact. The tip has to sit flat. Over a bony jaw angle or a hollow temple, a tip that rocks onto one edge squeezes the energy into a smaller area, and that edge is where a superficial burn usually starts.

The second is cooling. The surface stays protected only while cooling reaches it during each pulse; if that is interrupted, the outer skin takes heat meant for the layers below. The third is energy and passes. Piling extra pulses onto thin padding over bone is how the fat just under the skin can shrink and leave a dip, and extra heat in one spot doesn't add lift.

One thing surprises people: the heat you feel is part of the safety system. Monopolar RF settings are commonly adjusted to what the person feels, and the 600-treatment series above was done without injected anesthetic or IV sedation. If your face is numbed so deeply that you can't feel a hot spot, you've lost the signal that tells the operator to turn the level down or move on.

When a pulse feels sharp and hot, say so right away; your interpreter is with you through the treatment for moments like that.

With a lean face, I would rather leave a little tightening on the table than risk a dent over a cheek hollow. Thin padding over bone is also where I'd ask whether heat is the right tool at all. If you're used to a strong numbing cream from other treatments, tell me before we start, so we can agree how you'll signal a hot spot.

Ulthera or Thermage: which risks come with which?

The two put heat in different places. Ulthera uses focused ultrasound to create small heated points at set depths, down to the muscle and fascia layer. Its usual temporary effects are tenderness, bruising and welts along the treatment lines, and less often short-lived numbness or weakness if heat lands near a nerve. Thermage spreads heat more broadly through the skin and the layer just beneath it, so its rare problems are surface burns and fat loss; nerve effects aren't its typical concern.

I go through who suits each one in more detail in Thermage vs Ultherapy in Seoul.

Say you're 36, with an oval face, a softening jaw edge, and cheeks that were already slim in your twenties. You've read about dents and you're close to cancelling. I would look first at where the laxity sits. If it's mostly a soft jaw edge and looser skin texture, an RF treatment that avoids extra passes over the hollows can make sense. If the cheeks look hollow because volume is already gone, heat won't bring that volume back, and a volume treatment such as Sculptra belongs in the same conversation.

Someone with thicker skin and heavier lower-face tissue is a different case. There's more padding to absorb heat, so the question shifts to whether non-surgical tightening can show enough on tissue that heavy. Tightening of this kind gives a modest change; it doesn't do what surgery does for marked sagging.

Burns, dents and darker patches: who should wait, and what to do at home

In short, these are the situations where general medical advice is to hold off, or at least raise it before anything is booked:

• a pacemaker, defibrillator or other implanted electronic device
• pregnancy or breastfeeding
• an active skin infection, a cold sore or inflamed acne in the area
• isotretinoin within the past several months, a recent laser or peel, or a fresh sunburn
• filler, threads or metal implants in the treatment area, which change how heat should be placed
• a history of keloids, or of skin darkening after small injuries

Some of these are a firm no for monopolar RF; others are a matter of timing. How much tightening you see and how long it holds differ between people, and results vary with skin thickness, age and the laxity you start with.

If something appears once you're home, photograph it in daylight with the date, keep the area clean and out of the sun, and don't pop a blister or pick a crust. See a dermatologist or your GP if it spreads, weeps, or gets more painful after the third day, or if you notice a dip. A dip in the first weeks can partly be swelling around it, so it's worth a doctor's look before anyone injects filler into it.

Before you fly, find a dermatologist at home you could see at short notice, and keep a note of the device, the areas and the date to show them.

If any item on that list applies to you, put it in your WhatsApp message together with your flight-home date, and ask what you should do if a blister or a tender spot shows up after you're back.

Are the Thermage horror stories online true?

Partly. Three claims come up again and again, and they hold up differently.

Thermage melts fat. This is true only in the rare overheated case. At usual settings fat loss is not the expected effect, and a face that looks thinner a few weeks later is sometimes swelling going down, or age-related volume loss that was already under way.

You see the full result straight away. Not quite. There can be a slight early tightening as collagen contracts, and the change that counts builds over a few months as new collagen forms.

One bad session scars you for good. Scarring from RF is rare. Most burns are superficial and heal within a couple of weeks, though a darker patch can take months to fade. Many of the Korea gone-wrong stories you'll find are about surgery, which carries a different kind of risk from an in-office heat treatment. If you're also weighing a skin booster on the same trip, its risks are another category again, mostly bruising and small bumps at the injection points, as covered in Korean glass skin treatment side effects.

What decides the cost of Thermage in Seoul?

A handful of things move the figure for your case:

• the areas: full face, eyes, neck, or a combination
• the number of shots, which follows the size of those areas and how much laxity there is
• whether you have Duet Thermage alone or pair it with another lifting treatment such as Ulthera in the same visit
• whether you also want a separate concern treated on the trip; if texture or acne scarring is the real issue, RF microneedling is a different tool with its own cost logic, laid out in Potenza RF microneedling cost in Korea

Our full menu price list is published on the site, it's the same list Korean patients use, and VAT is added separately. For a sense of who Duet Thermage tends to suit before you ask, see Thermage in Seoul: Duet Thermage and who it suits.

Ask on WhatsApp what it would cost for your case: name the areas you care about, attach a front and side photo, and ask how the deposit and payment work, since both are settled after the consultation.

Fitting it into a Seoul trip

Book it early in your stay, not on your last day. Redness usually fades within a day, but if a blister or sore spot does appear, you want time to have it seen while you're still in Seoul. Skip saunas, hot baths and hard workouts for the first few days, and wear sunscreen and a hat while you're out walking.

We're a one-minute walk from Exit 5 of Myeongdong Station on Line 4, on the third floor of Korea Daeyungak Tower, and we're open Saturday and Sunday from 9 AM to 3 PM as well as weekday evenings until 8 PM. If you land on a Friday night, a Saturday morning visit leaves the rest of the trip for any redness to settle.

Send your travel dates and a daylight photo of the area you want tightened on WhatsApp, and add the one thing that's holding you back, whether that's old filler in your cheeks or a bad reaction to a previous treatment. The specifics for your face are settled at the consultation itself. There, the first thing I'll look at is how much padding sits over your cheekbones and jaw, because that tells me how much heat your face can take.
