Oligio and Thermage FLX are both monopolar radiofrequency devices that heat the skin to stimulate collagen. Thermage FLX delivers strong energy into the epidermis and dermis using core cooling; Oligio delivers energy to the dermis with a fine, precise current and is known for a gentle feel with no anesthesia needed. Neither replaces surgery, and the right choice for your skin is made in a one-on-one consultation with the doctor.
If you are researching non-surgical skin tightening in Seoul, Oligio and Thermage FLX will appear side by side on almost every clinic menu. They are easy to confuse because both use radiofrequency rather than ultrasound or laser.
This guide explains how each works, how they compare, what the session involves, what published studies report, and how to plan treatment at Glory Clinic in Gangnam if you are visiting Korea.
| Thermage FLX | Oligio | |
|---|---|---|
| Energy type | Monopolar radiofrequency | Monopolar radiofrequency |
| Where the energy goes | Into the epidermis and dermis | Down to the dermis |
| Comfort features | Vibration and cooling switch on before, during and after each pulse | Strong cooling and vibration modes; no anesthesia needed |
| What it aims to improve | Firmness and elasticity through collagen regeneration | Sagging skin, pores and skin texture through collagen remodeling |

How radiofrequency tightening works
Radiofrequency (RF) energy creates heat inside the skin. That controlled heat prompts the skin's own repair process: collagen remodeling and new collagen production, which is what makes skin firmer and more elastic. Because it relies on your body's response, the change builds over time rather than appearing all at once.
Both Thermage FLX and Oligio are monopolar RF devices, so the basic mechanism is the same. The differences lie in how each device delivers and controls that energy, and in how the treatment feels.
Thermage FLX: strong energy with core cooling
Thermage FLX is the latest, fourth generation of Thermage. Its core cooling technology minimizes damage to the skin's surface while delivering strong radiofrequency energy effectively into the epidermis and dermis.
Every pulse follows a set cycle. Just before the energy is delivered, the vibration and cooling functions switch on. The energy then travels down to the dermis while the surface cooling keeps working, and once the energy has been delivered, the surface is cooled once more.
At Glory Clinic, Thermage FLX is performed with the genuine device and genuine tips, and you receive a Thermage FLX genuine-tip certificate.
Oligio: a gentle-feeling option
Oligio delivers radiofrequency energy down to the dermis. A fine but precise current and radiofrequency heat promote collagen remodeling and production, aiming to improve sagging skin, pores and skin texture.
No anesthesia is needed, and strong cooling and vibration modes keep pain to a minimum. An effect can be seen right after treatment, and because collagen production continues afterward, the results can be expected to last.
Your session at Glory Clinic, step by step
1. One-on-one consultation with the doctor. The medical director looks at your skin and your goals and decides which device suits you, and the same doctor performs your treatment.
2. Treatment area design (for Oligio) or an explanation of the Thermage process (for Thermage FLX).
3. Cleansing and preparation.
4. The treatment itself, with the genuine device and the correct dose of energy.
5. Post-treatment care and aftercare instructions.
What published studies report
A retrospective review of more than 600 Thermage (monopolar RF) facial treatments found that the most common effects were redness and swelling that usually lasted less than 24 hours, with no permanent side effects; about 2.7% of treatments had temporary side effects that resolved. The treatments were given in an office setting without injectable anesthetic or IV sedation [1].
A prospective study of Oligio, a new-generation monopolar RF device, in 30 Asian volunteers (Fitzpatrick skin types III to V) with mild-to-moderate lower-face laxity reported improvement right after a single treatment, with continued improvement at 1, 3 and 6 months. The average pain score was 3.13 out of 10 and no serious adverse events were observed [2].
These are individual studies with their own limits. Results vary from person to person, and neither treatment is a substitute for a surgical facelift.

Frequently Asked Questions
What is the main difference between Oligio and Thermage FLX?
Both are monopolar radiofrequency devices. Thermage FLX delivers strong energy into the epidermis and dermis using core cooling; Oligio delivers energy to the dermis with a fine, precise current and is known for a gentle feel.
Which is more comfortable, Oligio or Thermage?
Oligio needs no anesthesia, and its strong cooling and vibration modes keep pain to a minimum. Thermage FLX also switches on vibration and cooling before, during and after each pulse to protect the surface.
Do I need anesthesia?
Oligio needs no anesthesia. Your doctor explains comfort measures for either treatment at the consultation.
Is there downtime?
In a large review of Thermage treatments, the most common effects were redness and swelling that usually settled within 24 hours. In a study of Oligio in Asian patients, no serious adverse events were observed.
When will I see results?
Oligio can show an effect right after treatment, and collagen production continues afterward. Because RF works through your own collagen response, change builds over time for both treatments.
Can I have treatment during a short trip to Seoul?
Yes. Same-day treatment is available at Glory Clinic. Share your travel dates when you book so the plan fits your trip.
Do Oligio or Thermage replace a facelift?
No. They are non-surgical treatments for firmness and skin quality and are not a substitute for surgery.
How do I know the device is genuine?
Glory Clinic uses the genuine Thermage FLX device and tips and gives you a genuine-tip certificate. Oligio is also performed with the genuine device and tips.
Key Summary
- Oligio and Thermage FLX are both monopolar RF treatments that stimulate collagen.
- Thermage FLX: strong energy into the epidermis and dermis with core cooling. Oligio: precise current to the dermis, gentle feel, no anesthesia.
- Published studies report mostly short-lived redness and swelling and no serious adverse events, but results vary and neither replaces surgery.
