How it works
Thermage uses monopolar radiofrequency energy delivered through a cooled tip. The energy heats the deeper dermis and connective tissue while the surface is protected by cooling. This heat causes existing collagen to contract right away and triggers your body to produce new collagen over the following months.
The result is gradually tighter, smoother, firmer skin. Thermage is FDA-cleared, and the current-generation system is Thermage FLX.
During treatment you feel brief deep heat with each pulse, followed by cooling. Numbing cream is applied first, and the energy level is adjusted to your comfort.
How it compares
| Compared with | Difference |
|---|---|
| Ultherapy | Ultherapy uses focused ultrasound to reach the deeper SMAS layer for lifting, while Thermage uses radiofrequency for broader skin tightening. |
| Thermage FLX | Thermage FLX is the newer generation with a larger tip and more even energy delivery, often allowing faster, more comfortable treatment. |
| Shurink | Shurink is a Korean focused-ultrasound lifting device and is often combined with Thermage for both lift and tightening. |

Frequently asked questions
How much does Thermage cost in Seoul?
Price depends on the area and number of shots (pulses), for example full face versus eyes. Message us on WhatsApp for current options and the doctor confirms the exact plan and quote at consultation before treatment. Because every face and skin type is different, the doctor confirms what is suitable for you during your consultation, and results vary from person to person.
Does Thermage hurt?
You feel short bursts of deep heat followed by cooling. Numbing cream is applied beforehand, and the doctor adjusts energy levels to keep you comfortable. Most people find it tolerable, with bony areas more sensitive. If you are visiting Seoul for a short time, tell us your travel dates when you book so the doctor can plan treatment timing around your flight.
When will I see results?
Some people notice slight tightening right away, but the main collagen-related improvement develops over 2 to 6 months. Results vary with age, skin condition and lifestyle. Our English-speaking team can answer follow-up questions on WhatsApp or KakaoTalk before your visit and after you return home.
Can I fly after Thermage?
Yes. There is no downtime, so you can fly the same day. Keep skin hydrated on the plane and use sunscreen at your destination. The doctor will also review your medical history, current medications and any previous treatments before recommending anything.
Thermage or Ultherapy, which is better?
They work differently. Thermage tightens skin with radiofrequency, while Ultherapy lifts deeper tissue with ultrasound. Many patients combine both. The doctor recommends based on your degree of laxity and goals. Written aftercare instructions in English are provided, and you can message us any time if something does not feel right.
How long does Thermage last?
Results can last up to 12 months or more, depending on skin condition and lifestyle. Many people repeat it yearly to maintain firmness. Aging continues, so results are not permanent. Booking early in your trip also leaves time for a quick check with the doctor before you leave Korea, if one is needed.

Thermage in Hongdae – Non-Surgical Skin Tightening That Works
Ready to smooth, firm, and rejuvenate your skin without downtime? Thermage® is a trusted, non-invasive skin tightening treatment that uses radiofrequency (RF) technology to stimulate collagen and improve skin texture. At our Hongdae clinic, we offer Thermage for patients looking to lift sagging skin, reduce fine lines, and restore youthful definition—with natural-looking results and no surgery.
What is Thermage?
Thermage® is an FDA-cleared procedure that uses focused radiofrequency energy to heat the deeper layers of the skin. This gentle heating triggers your body’s natural collagen production, leading to tighter, smoother, and firmer skin over time.
Unlike lasers, Thermage works on all skin types and tones and doesn’t require recovery time, making it ideal for those with busy lifestyles.
Common Treatment Areas:
- Forehead and eye area (non-surgical eye lift)
- Cheeks and jawline (jaw contouring)
- Neck and décolletage (tightening loose skin)
- Abdomen, thighs, arms, and knees (body firming)
Key Benefits of Thermage

- ✅ Single-session treatment: Most patients see results after one session
- ✅ Long-lasting results: Effects continue to improve for months and last up to a year or more
- ✅ Full-face and body solution: Safe and effective for multiple areas
- ✅ Safe for all skin types: Customizable settings ensure comfortable treatment
Is Thermage Right for You?
You may be a good candidate for Thermage if:
- You have mild to moderate skin laxity
- You want to firm and contour your skin without surgery
- You are not ready for a facelift but want visible results
- You prefer treatments with little to no downtime
Thermage is suitable for adults of all ages and is especially popular among those in their 30s to 60s who are beginning to see signs of aging or sagging.
What to Expect
Before Treatment:
A consultation will be conducted to assess your skin and customize the treatment plan. No special preparation is needed.
During Treatment:
You’ll feel a brief heating sensation with each pulse, followed by a cooling effect for comfort. Treatment usually takes 45–90 minutes, depending on the area.
After Treatment:
There’s no downtime—you can return to your normal activities immediately. Some patients may experience slight redness or swelling, which fades quickly.
When Will You See Results?
Initial tightening can often be felt right after the procedure, but the full benefits develop gradually over 2–6 months as collagen regenerates. Results can last up to 12 months or more, depending on your skin condition and lifestyle.
Thermage vs. Other Treatments
Unlike Ultherapy (which uses ultrasound), Thermage uses radiofrequency to treat the skin’s deeper layers. It’s particularly effective for surface-level texture and fine lines while also offering skin-tightening benefits. It can be used alone or combined with other treatments like fillers or laser rejuvenation for comprehensive anti-aging care.
