Thermage in Suwon: what changes right after treatment and a few months later?
If you are looking into Thermage because your jawline has become less defined and your skin feels thinner, it helps to first understand when and how the results appear. Thermage is a radiofrequency lifting treatment that delivers radiofrequency heat to the dermis to contract collagen fibers and then encourages new collagen to form over the following months.
Right after treatment, the heated collagen contracts and you may feel a tightening sensation, while changes in firmness and skin texture build up gradually over 2 to 4 months. That is why the right way to judge is to compare a few months later against photos taken before treatment, rather than what you see in the mirror on the day. At the Suwon clinic, during consultation we first look at whether the sagging comes from the skin layer or from deeper layers, then decide the number of shots and any treatments to combine.
In this article, we go through what radiofrequency heat does inside the skin, the difference between right after treatment and a few months later, the process and how the number of shots is decided, recovery and care, and side effects in order.
Thermage key points
- Radiofrequency heat contracts collagen in the dermis and then stimulates the formation of new collagen.
- The tightness right after treatment eases within a few days, and changes in firmness appear gradually over 2 to 4 months.
- Results vary from person to person, but they are known to last about 1 to 2 years, so a maintenance treatment about once a year is considered.
- If the cause is not the skin but fat position or sagging in deeper layers, treatments that address other layers are reviewed alongside.
Where in the skin does Thermage deliver heat?
Collagen and elastin, which support firmness, are spread like a mesh mainly in the dermis. As we age, this mesh loosens and thins, and the skin feels thinner, with fine lines, a less defined jawline, and sagging pores appearing together.
This device cools the skin surface while concentrating radiofrequency energy in the dermis beneath. Thermage FLX has a wide tip area, along with features that adjust energy to the skin with each shot, cooling, and vibration, which help heat be delivered evenly even though skin thickness differs across areas of the face.
It does not lift the skin directly; it works on the skin's own firmness and density, so even with the same number of shots, the change you notice differs depending on what caused your facial contour to lose definition.
How do Thermage results differ right after treatment and a few months later?
The two changes come from different processes inside the skin, so they are easier to understand when looked at by period. The table below separates what happens inside the skin and the changes you notice on the outside by period.
| Period | What happens inside the skin | Changes you notice on the outside |
|---|---|---|
| Right after treatment | Heated collagen fibers contract | The skin feels tight and taut |
| Over a few weeks | New collagen begins to form as the skin recovers from the heat stimulus | Visible changes are still small |
| 2 to 4 months | New collagen settles back into place | Changes in skin texture, fine lines, and firmness around the jawline |
If you judge within a few weeks after treatment, it is before collagen has settled, so it is easy to feel there is no effect. If the sagging comes from cheek fat that has moved down or from significant volume loss, working only on the skin layer may feel like a small change, so ultrasound lifting that addresses deeper layers or volume treatments are reviewed alongside.
How is Thermage FLX performed at the Suwon clinic?
How the number of shots is determined
The number of shots is decided by looking at whether loss of firmness is spread across the whole face or concentrated in areas such as the jawline and cheeks, whether the skin is thin or thick, and whether the sagging stops at the skin layer or extends into deeper layers. Thick, oily skin, such as men's skin, spreads heat differently, so intensity is adjusted to skin thickness. Shot options include 300 shots, 600 shots, and 1,200 shots that can be split over two sessions, and if sagging extends into deeper layers, there are also options combined with ultrasound lifting.
Treatment steps at our Suwon clinic
- Personalized Consultation
- Photos (Before Treatment)
- Numbing Cream (about 30–60 minutes)
- Treatment
- Soothing Care
Numbing cream is left on for about 30 to 60 minutes, and if you feel strong heat during treatment, let us know and we will adjust the intensity in that area. Photos taken before treatment are used as the baseline for comparing changes a few months later, and you are consulted again around a year later to decide whether to have a maintenance treatment.

Recovery and care after Thermage
- On the day of the procedure, avoid hot saunas, drinking and strenuous exercise.
- For a week, take a break from harsh care such as peels and scrubs.
- Apply plenty of moisturizer and always wear sunscreen when you go out.
- If redness or swelling lasts a long time, contact the clinic.
If the skin keeps being exposed to UV rays and dryness during the months when collagen is forming, changes in firmness can be masked. Keep up moisturizing and sun protection after treatment, and setting a time in consultation to compare with your first photos makes it easier to judge the change.
Side effects and precautions of Thermage
Common reactions include redness, a sensation of heat, mild swelling, and a dull ache when pressed, and most settle down over time. How strongly you feel the heat and how quickly you recover vary by area, skin thickness, and individual.
Rarely, small burns or blisters, temporary numbness, or slight hollowing in part of the face may occur. The risk increases when heat overlaps in the same spot or strong energy goes into areas with thin skin and little fat, so intensity is adjusted separately for each area. Please tell us before treatment if you have an electrical device or metal implant in your body, such as a pacemaker, are pregnant, or have inflammation or a wound in the treatment area.
If redness and swelling persist for several days, blisters form, or pain keeps getting worse, please contact the clinic right away.
What is checked before Thermage?
If these apply to you, start by checking the cause of sagging
- The first thing you notice is that your skin has become thinner and fine lines have increased.
- Your jawline has become less defined, but you are unsure whether cheek fat has moved down.
- When you had it before, you noticed a change only right after, and were unsure about changes afterward.
- Pores, skin texture, and firmness all bother you.
If two or more apply, it is best to first check whether the sagging comes from the skin layer or from deeper layers before radiofrequency lifting. Whether to treat, the method, and the number of shots are decided together in consultation after a physician's examination.
In short, Thermage is judged by collagen changes over several months rather than the tightness right after, and the key is to choose any combined treatments according to the cause of the sagging.
FAQ
Q. When can I feel the effects of Thermage?
A. Right after treatment, collagen contracts and you may feel tightness, while changes in firmness and skin texture appear gradually over 2 to 4 months. That is why it is best to judge the change by comparing photos taken before treatment with photos taken a few months later.
Q. What should I do if I feel Thermage had no effect?
A. First we check how long it has been since treatment, and look again at whether the cause of the sagging was fat position or volume change. If collagen has not yet settled, we wait a bit longer, and depending on the cause, we discuss whether to add a treatment that addresses other layers.
Q. Can men get Thermage too?
A. Yes, you can. Men's skin tends to be thick and oily, so heat spreads differently. That is why we first check areas where sagging is concentrated, such as the jawline and cheeks, and set the number of shots and the intensity for each area according to skin thickness.
Q. How is Eye Thermage different from facial Thermage?
A. A small dedicated tip designed for thin skin such as the eyelids is used, and the treatment is done while wearing lenses that protect the eyes. Sagging around the eyes can be caused not only by the skin but also by fat and muscle, so the cause must be examined first.
Q. How often should I get Thermage?
A. Results vary from person to person, but they are known to last about 1 to 2 years, so a maintenance treatment about once a year is considered. When you have it again, the number of shots is decided by comparing with your first photos to see how skin thickness and firmness have changed.
Q. How can I find out the cost of Thermage?
A. The cost depends on the number of shots and any treatments combined with it. We confirm in consultation how many shots to use for the whole face and whether to combine other lifting treatments before giving you details, and items by option can also be found on the treatment information page.
