"I got it last year, do I need to get it again this year?"
"I feel like it worked, but I'm not really sure."
This is the question people who have tried Thermage ask most often the following year.
Hello, I am Kwon Si-jin, the representative director who will be practicing at DA Clinic Myeongdong ^^
We're getting ready to open our doors in Myeongdong soon, and since so many people ask about the timing of a repeat treatment, I wanted to put this together for your information first.
Thermage is generally planned around once a year. That is because it takes about that long for collagen to rebuild itself.
However, there is something else to check before looking at the calendar.Let's look step by step at what criteria you should use to decide the timing.
Why a year
Thermage is described as delivering radiofrequency (RF) energy across the dermis as a plane.
Where ultrasound lifting drives energy in point by point, radiofrequency warms a broad surface evenly.So the way the effect appears is different too.
When heat goes in, existing collagen contracts first.That light tightness you feel right after the treatment is that response.And then fibroblasts are stimulated and new collagen begins to form.
That second process takes time.It builds over several months, holds for a period, and then gradually returns to your original rate of ageing.
It's natural to time the next session to the point where that curve turns, and that point is generally spoken of as around a year.
How the effect appears
- Right aftera mild tightening. Not dramatic
- 2–3 monthscollagen builds and the change begins
- 3–6 monthsdescribed as the period when it shows best
- After thatgradually back to the ordinary rate
Rather than going by the calendar alone, it's better to watch that curve and judge the next point from it.
Photographing the same area under the same lighting and at the same angle before you start and three months on makes judging it far easier.The change is gradual enough that memory alone won't hold it.
How the day itself goes
To make sense of the interval, it helps to know how the day runs.
- Mappingthe areas are divided while you're sitting up. Lying down changes where the sagging appears to sit, and the lines can miss the places that actually need work
- Checking the tipthe genuine tip is opened and the number of shots per area is decided. A set shot count is tied to the tip
- Deliverythe intensity is varied area by area. Thin skin and thick skin don't get the same setting
- Finishinggenerally described as around an hour, and often done without separate anaesthesia
What's worth watching here is whether the intensity is divided by area. Pushing one setting from start to finish concentrates the strain on the thin areas. And that strain can come back later as "the effect felt short."
What you do in the months afterwards
With Thermage, it's the months that follow rather than the treatment itself that make the result, because that's the period when collagen builds.
So how you look after your skin during this time carries straight through into how long it holds.
- Sun protectionUV is spoken of as the single largest factor that erodes collagen. If it's being eroded while it builds, less of it remains
- Moisturisingduring recovery it's better to lean on hydration rather than active, irritating ingredients
- Saunas and hard exercisesafer to postpone for a week or two right after the treatment
The difference between "it lasted a year" and "it only lasted six months" is sometimes not a difference of device but a difference in these few months.
Would more often be better?
No.
Building collagen takes time.Applying heat again before that response has finished accumulates burden faster than additional benefit.
The wish to come in early when the effect seems to be fading is entirely understandable — but in that case, it's better to look first at why it felt short than to shorten the interval.
If it's all radiofrequency, why several devices?
Not all radiofrequency is the same radiofrequency.Depending on how the electrodes sit, what frequency is used and how the surface is cooled, the depth it reaches and how it feels change even when the same dermis is being warmed.
Let me take one question that comes up often here.
- Thermage FLXmonopolar, warming the whole dermis evenly. It has a function that reads the skin's resistance and matches the energy to it, and is described as having lowered the pain through cooling and vibration. Usually done without anaesthesia
- XERFdescribed as using two frequencies together to reach deeper layers. It has cooling and tends to be less painful, and comes up for people with little facial fat
- Volnewmermonopolar radiofrequency, even from the dermis through to the subcutaneous layer. Described as being on the fuller, more voluminous side of firmness
- InModethe firmness mode and the fat-side mode are separate, and it comes up when the jawline is being considered alongside
So when the Thermage interval feels short, the answer is sometimes not the same device more often but a different device once.That's the practical reason for separating them into families.
If it felt short, what to look at first
- Whether you received the set number of shots with a genuine tip
- Whether the energy plan per area suited the thickness of your skin
- Whether sun protection and moisturising held up afterwards
- Whether the main issue was in fact sagging rather than firmness
That last one matters most.Where sagging runs deep, radiofrequency tightening alone has its limits, and shortening the interval will still leave you wanting.
This isn't a problem that changes device solves — it's a problem of which layer is being targeted.However well you warm the dermis, it can't lift what has descended in a deeper layer.
So we separate them into families
Inside the single word "lifting" sit families with quite different characters.
- Radiofrequency (RF)the dermis, as a plane. Firmness, skin texture, pores. Thermage FLX, InMode, XERF, Volnewmer
- Ultrasound (HIFU)deep layers, point by point. Lifting what has descended. Ultherapy PRIME, Shurink Universe, Sofwave
- Microwavereaching the fat layer. Tidying the contour. Onda
The reason we have all three families at our Myeongdong clinic is that we have to be able to say "this isn't a Thermage interval problem."
With only one device, every consultation drifts towards shortening that one device's interval. That isn't a good order of things for you.
There's no need to rush in these cases
- If three months haven't passed yet — the change hasn't finished emerging
- If you have relatively little fat — excessive energy is associated with a hollowed look
- If your skin is inflamed
And please tell us in advance if you have a pacemaker, metal implants in the treatment area, or are pregnant.Dental titanium implants are described as not falling into this category.
- Around one year is the baseline
- Watch how collagen refills rather than the calendar
- Depending on skin condition, we bring it forward or push it back
Frequently asked questions
Q. Once I've had it, do I have to keep having it?
A. Ageing continues regardless of treatment, so it's hard to see this as a one-and-done treatment. That said, it isn't something you must continue, and stopping doesn't leave you worse off than before.
Q. Can I alternate it with other lifting treatments?
A. Treatments targeting different layers are sometimes planned together.Order and interval matter, though, so it's safer to settle that in consultation.
Q. I'm worried my cheeks will look hollow.
A. Where there's little fat and the energy is excessive, that change is sometimes mentioned. Which is why looking at the plan before the intensity matters.
Q. I heard you can go stronger with anaesthesia.
A. It's true that less pain creates room to raise the energy. But raising the intensity isn't always better, and the thickness of your skin and the amount of fat have to be considered together.Plan before intensity.
Q. Are more shots better?
A. Enough to cover the area evenly is necessary; beyond that it moves towards strain.Genuine tips have a set shot count, so check the tip and the shot count together.
Q. It feels like nothing has changed — has it failed?
A. Start by checking when you're judging it. Two or three months in, the change hasn't finished emerging, so a conclusion drawn from that impression will be off.Comparing a photo from before you started with one at three months, under the same conditions, is more accurate.
Q. From what age do people have this?
A. Your skin's condition, not your age, is the measure. Many begin when firmness starts to drop, but if the change isn't yet clear there's no reason to hurry.
Watch the collagen, not the calendar
If I leave you a single line, it's this.
Take a year as the baseline for Thermage, but set the timing by how collagen is building rather than by the calendar.
