What is Thermage? Why it's called a "facelift without surgery"
So many patients walk in and tell me, "Doctor, when I look in the mirror my face just doesn't feel as firm as it used to, the jawline is starting to blur — but I'm not ready for surgery." I understand that feeling completely. It's that in-between stage where creams can no longer keep up, but you're nowhere near needing the operating table. Thermage was made for exactly this stage.
Thermage is a skin-tightening device that uses Monopolar Radiofrequency (RF) to deliver heat into the dermis, prompting collagen to contract and rebuild. The result is smoother, firmer, tighter skin — with no wounds, no surgery, and no downtime. That's why people have come to call it a "facelift without surgery."
This isn't some new device that just appeared out of nowhere. It's been in the aesthetics field for over 20 years, developed through several generations up to the latest model, Thermage FLX, and it's cleared by the U.S. Food and Drug Administration (FDA). That's one of the reasons I'm comfortable recommending it — it has a long track record of use and a body of safety data behind it.
- Uses radiofrequency (RF) to heat the dermis → collagen contracts immediately + rebuilds over the long term
- Excels at "smooth, firm skin across the whole face" — not a surgical lift
- One session, no wounds, go straight home; results last around 1-2 years
- Cleared by the U.S. FDA — backed by safety data
How it works — heat that prompts skin to build new collagen
Got questions? Dr. Time offers personalized, honest consultations — no upselling.
Consult via WhatsAppA lot of people hear "radiofrequency heat" and can't quite picture how it's any different from pressing something hot against the face. Let me paint the picture for you.
The Thermage tip delivers RF waves that build up heat in the dermis, at a depth of roughly 2.5-3 millimeters — the layer where our collagen lives. The heat there does two things at once. First, the existing, sagging collagen fibers "contract" immediately, like a tendon that tightens up when heated, so your skin feels a little firmer from the very first day.
But the real star is the second part — this controlled heat stimulates the collagen-producing cells (fibroblasts) to wake up and gradually build new type 1 and type 3 collagen to replace the old. This process takes time; it doesn't happen in a single day. Research has found that new collagen formation takes clear shape over the 3-6 months after treatment. That's why Thermage results keep getting better and better, rather than appearing in a flash and then stopping.
What I love about this technology is that the tip cools the upper skin at the same time as it delivers heat to the deeper layer, so the top layer of skin doesn't burn — the heat goes to work only in the spot we actually want. Histopathology studies have found orderly new collagen formation, without causing scarring or damaging the upper skin.
Thermage vs HIFU/Ulthera — what's the difference, and which is better?
This is the question patients are most confused about, and the advertising out there loves to muddy it about which one is "better." I want you to understand this first: they're not rivals where you have to pick a side — they do different jobs.
An easy way to remember it: Thermage excels at the "skin" (smooth, firm, tighter pores), while HIFU/Ulthera excels at the "lift" (sharpening the jawline), because the waves they use reach different layers.
| Topic | Thermage (RF) | HIFU / Ulthera (Ultrasound) |
|---|---|---|
| Energy type | Monopolar RF radiofrequency | High-intensity focused ultrasound (HIFU) |
| Reaches the layer | Dermis ~2.5-3 mm (spread as a volume) | SMAS layer ~3-4.5 mm (focal points) |
| Strength | Smooth, firm skin across the whole face, smaller pores | Lifting and tightening the jawline, jowls, chin |
| Sensation during treatment | Sharp bursts of heat in rhythm (newer model hurts less) | Deep stings down to the bone, point by point |
| Clear results | 2-6 months | 2-3 months |
| Best for | Skin starting to sag, wanting a firm whole face | A sagging jawline, wanting it sharper |
In many patients, I recommend doing both to complement each other, because they work on different dimensions — HIFU lifts the framework to make it sharp, then Thermage makes the skin wrapping it smooth and firm. The combined result looks more natural and complete than either one alone. But if the budget is tight, I'll ask whether your main concern is "sagging" or "not smooth," and then choose the one that answers that first.
How many months until results, and how long they last
Patients often ask me, with a slightly impatient tone, "Will my face bounce back right away?" I have to be honest so you set the right expectation. Thermage isn't a treatment that transforms you the instant it's done, like filler. It "wakes up" your skin to build its own collagen, so it needs time.
- Day one — Skin feels a little firmer from the existing collagen contracting; there may be slight redness.
- 2-4 weeks — The early firmness fades somewhat. Don't panic and wonder where it went — this is the stage where your body is just getting to work.
- 2-3 months — New collagen starts to show clearly; skin genuinely begins to feel firmer.
- 4-6 months — Results reach their peak; skin is at its firmest and smoothest in this window.
Studies that followed patients found that results usually peak at around 3-4 months and may keep improving up to 6 months, all from a single session. As for "how long it lasts," the answer is about 1-2 years — that number isn't fixed; it depends on your age, skin quality, genetics, and, importantly, how you take care of yourself. People who wear sunscreen consistently, don't smoke, and rest well see their results last longer.
If, two weeks after treatment, you feel "wait, that early firmness is gone" — don't worry at all, that's completely normal. The day-one firmness was the existing collagen contracting, while the real, lasting result is forming inside. Wait until 2-3 months and take a comparison photo — you'll see the difference for yourself.
Does it hurt? The question I'm asked most often
Let me speak plainly about this, because it's what people worry about most and many clinics don't talk about it. Yes — the older Thermage models were known for the sharp heat when firing energy; some people described it as "like being flicked by something hot, in rhythm." I don't want you running into exaggerated information on either side — neither the claim that it doesn't hurt at all, nor the claim that it's absolute torture.
The truth is, the newer Thermage FLX was designed specifically to fix this. The tip has a vibration system while delivering energy, which helps distract the nervous system's perception of pain (the same principle as rubbing a spot that hurts and feeling better). Combined with automatic energy adjustment that delivers just the right amount of heat for each spot of skin — not overdone to the point of unnecessary stinging — most patients tolerate it comfortably without general anesthesia.
At my clinic, I always apply numbing cream before treatment, and during the procedure I keep asking you, "Is this level okay?" — it can be adjusted up or down the whole time. There's no forcing the energy up just to finish quickly, because your peace of mind matters more.
And what about downtime?
The good news is Thermage has almost no downtime. You can go right back to work afterward. The most common side effect is mild redness that fades within a few hours to a day, or a little swelling for 1-2 days in some people. No wounds, no scabs, and you can wear makeup the next day. This is what makes Thermage suit working people who don't have time to take off.
Who Thermage suits, and who should consult first
I want you to know yourself before deciding, because Thermage isn't the answer to every problem. If you come in with the wrong expectation, you might feel "I did it and saw no difference" when in reality it just didn't match your particular concern.
Suits you if
- Your skin is starting to sag in the early-to-mid stages and feels less firm than before
- You want smooth, firm skin with tighter pores and a healthy look
- You're a working person with no time for downtime and want a one-and-done session
- You're afraid of needles and don't want anything injected into your skin
- You're starting to see shallow fine lines, or the skin under your chin or along your jawline is beginning to sag
Consult the doctor first if
- Your skin is very lax, or you have clearly drooping eyelids (you may need to consider other options as well)
- You're pregnant or breastfeeding
- You have a pacemaker or an implanted electronic device
- You have an infection or wound at the treatment area
- You expect a surgical-style "lift" in a single session
If you're in the left-hand group, Thermage should serve you well. But if you're in the right-hand group, it doesn't mean you can't do it — I'd just like to have a clear conversation with you first, to plan around your real concern.
Thermage FLX vs the older model (CPT) — what's the difference
When you read reviews you'll find the model names jumbled together until it's confusing — Thermage CPT, Thermage FLX. Let me sum it up simply: FLX is the model developed from CPT, improved in three main areas.
One — faster. The FLX tip is larger, up from 3 to 4 square centimeters, meaning it covers more area per shot, so treatment is shorter, you sit for less time, and it's more comfortable. Two — more precise. FLX has the AccuREP system that measures and adjusts the energy to suit the resistance of each spot of skin automatically — thicker areas get just the right amount, thinner ones don't get overdone. Three — less painful thanks to the tip's vibration system I mentioned earlier.
If you ask whether you must choose FLX — my advice is that if you can choose, go with the newer model, because you get both more comfort and more precision. But what matters even more than the model is the person holding the tip — the physician's technique and assessment affect the outcome more than the model number ever will.
What drives the price of Thermage
I understand price is what you want to know from the start, but I'd rather not toss out a floating number, because Thermage has factors that can make the price differ quite a bit, and I want you to understand what you're paying for.
What is the price based on?
The heart of the Thermage cost is the "tip." Each tip is single-use and comes with a set number of "shots" built in — for example 600 shots, 900 shots, or 1,200 shots. The wider the area you treat (whole face + neck), the more shots you use, and the higher the price. This is why treating just the face costs differently from treating the whole face and neck.
Why does the price differ from place to place?
Two things I want to warn you to watch out for. One is a genuine tip and the real shot count — some unusually cheap promotions may use fewer shots than they should, or use non-genuine materials. Two is whether a real physician does the treatment, because the energy settings and technique affect both the result and safety. The cheapest isn't always the best value.
- The tip is genuine, and they open it to show you the real shot count in front of you
- A physician does the treatment, assessing your skin and setting the energy to suit you
- There's aftercare and consultation after treatment — not just done and finished
At Depry, I want you to know the clear price before treatment, along with an explanation of how many shots the tip uses and which areas are being treated, so you can decide on real information. Feel free to ask about updated prices and promotions on LINE first.
Thermage in Phitsanulok — Depry Clinic
If you're in Phitsanulok or a nearby province and looking for somewhere to do Thermage, I'd like to invite you to come and talk first. There's no rush to decide. Dr. Time will sit and really look at your skin, listen to what worries you and what kind of result you want, and then tell you honestly whether Thermage answers your needs, or whether there's another option that suits you better.
I believe good skincare doesn't start with the device — it starts with understanding what you want and planning something that fits your skin and your budget, rather than selling everything we have. Being treated by a physician who cares for you continuously — whatever the result, I'm right here to keep looking after you — is what I want you to receive.
- It excels at "smooth, firm skin across the whole face" — if you want to "lift the jawline," think of HIFU/Ulthera alongside it
- Results build gradually over 2-6 months and last 1-2 years; one session, no downtime
- The FLX model hurts far less, but the most important thing is having it done by a physician who can assess and set the energy properly
Frequently Asked Questions
Does Thermage hurt?
The newer FLX model hurts far less thanks to the tip's vibration system and automatic energy adjustment. Most people tolerate it without sedation. I'll apply numbing cream and keep checking in to make sure you're okay — the level can always be adjusted.
How soon do you see Thermage results, and how long do they last?
Skin feels a little firmer right after treatment, but the real result shows clearly over 2-6 months from the new collagen, and lasts about 1-2 years, depending on how you take care of yourself.
Thermage vs HIFU/Ulthera — which should I do?
Thermage excels at smooth, firm skin across the whole face, while HIFU/Ulthera excels at lifting the jawline. Many people do both to complement each other. I'll look at your skin first before recommending.
How many Thermage sessions do you need, and how often?
Usually a single session shows results, then you leave a gap of about 1-1.5 years before repeating to maintain the result.
How is Thermage FLX different from the older model?
FLX fires faster, is more precise (the AccuREP system), and hurts less thanks to the vibration system. In short: faster, more comfortable, more precise heat control.
Is Thermage dangerous?
It's cleared by the U.S. FDA and safe when performed by a physician. Side effects are usually just mild redness or slight swelling for 1-2 days. Choosing to have it done by a real physician matters most.
Do I need downtime after Thermage?
Almost none. You can go back to work afterward and wear makeup the next day. I recommend wearing sunscreen and keeping your skin moisturized.
What age is Thermage right for?
People usually start to notice sagging skin from their late 30s to 50+, but it depends on each person's skin condition. I'll assess your case honestly.
