In Thermage consultations, we often receive the question, "Isn't it true that the more painful it is, the better the effect?"
To put it simply, the intensity of pain and the Lifting & Tightening effect are not proportional.
In fact, repeatedly enduring unbearable stimulation can increase the risk of side effects like burns.
So today, we've summarized the criteria we prioritize when determining intensity in the consultation room.
Please take just one minute to read this.
Is it true that the more painful, the better the effect?
Radiofrequency Lifting & Tightening works by applying thermal stimulation to the collagen deep within the skin to improve elasticity.
If the stimulation is strong, the heat is also delivered more intensely, so the perception that pain equals effect naturally took hold.
However, this equation is not as simple as it seems.
There is an animal model study that examined the effect of radiofrequency energy on collagen in aged facial ligaments (Oh S. et al., Cells, 2025).
This study reported that collagen-related responses were more favorable under relatively lower power conditions than higher power.
However, since this is a study conducted on animal models, it cannot be definitively applied directly to human treatment results.
This study suggests that simply increasing the intensity may not be the answer, and that an approach of adjusting the pain within a tolerable range may be more reasonable.
The same applies to devices like Thermage FLX and Oligio, which use monopolar RF.
Adjusting the energy within the patient's tolerable range while continuously checking for pain is closer to safety than simply applying strong stimulation.
The same context was also discussed in Why we don't judge Thermage shot counts by numbers alone.
What's the difference between strong intensity and customized intensity?
Here's a summary of the differences between the two methods.
| Category | Unconditionally Strong Intensity | Customized Intensity for Skin |
|---|---|---|
| Criteria | Intensity of pain | Skin thickness, elasticity, sensitivity |
| Pain | Can be extreme | Within tolerable range |
| Risk | Increased possibility of burns, side effects | Direction to lower risk |
| Aim | Strong at once | Consistent, tailored to condition |
Rather than excessively increasing the intensity to improve skin elasticity, a method of consistent management with energy tailored to the individual's condition may be more helpful.
For concerns like nasolabial folds, where the area and sagging patterns differ for each person, the combination of devices itself needs to be re-evaluated. This part is explained in detail in How to combine Ultherapy, Thermage, and Oligio for nasolabial fold Lifting & Tightening.

Why do we check skin condition first?
To expect good results from Thermage FLX, the key is to first sufficiently understand the skin condition, not the pain intensity.
This is because the appropriate energy and areas to focus on differ depending on skin thickness, areas with reduced elasticity, and sensitivity.
At O.N Clinic, we measure and analyze skin condition with the AI skin analyzer Muse before consultation.
The process of designing the intensity based on these results generally proceeds as follows:
- Measure skin thickness, elasticity, and sensitivity with a skin analyzer before consultation.
- Medical staff analyze the measurement results to identify areas where energy should be concentrated.
- Design intensity and discuss treatment direction tailored to the individual's condition.
This process may lead to a slightly longer waiting time before the consultation.
Nevertheless, it is a procedure to reduce the risk of side effects and determine the appropriate direction for each patient.
For treatments like Thermage FLX, which involve a cost burden, the importance of thoroughly checking the skin condition becomes even greater.
If you are new to the device, reviewing What to check before Oligio X treatment may also help with your decision.
Before treatment, keep these points in mind
The effects and reactions of Thermage FLX may vary depending on the individual's skin condition.
Knowing the possible reactions after treatment in advance can help prevent alarm.
- Temporary pain, redness, swelling, heat sensation
- Rarely, burns or pigment changes may occur
- Recovery patterns vary depending on individual skin condition
(※ The applicability and intensity of the treatment must be determined through consultation and examination by medical staff.)
Rather than relying solely on online information, it is safer to determine whether to proceed with the treatment after checking your actual skin condition.
Post-treatment care can also affect the maintenance of the effect, so we recommend familiarizing yourself with the instructed care methods and thoroughly clarifying any questions through consultation.
Frequently Asked Questions
Is more pain associated with better results?
No, that is not the case. Strong intensity and extreme pain do not guarantee better results.
It is more important to proceed with appropriate energy tailored to your individual skin condition, and excessively strong stimulation can increase the risk of side effects such as burns.
What criteria are used to determine intensity?
The medical staff designs the intensity by comprehensively considering skin thickness, areas with reduced elasticity, and sensitivity.
Using skin measurement tools or AI analysis devices can enable more precise judgment. It is always safer to determine the applicability and intensity through consultation with medical staff.
What reactions can occur after the procedure?
Temporary pain, redness, swelling, and heat sensation may occur, and rarely, burns or pigment changes may develop.
Reactions vary depending on individual skin condition, so sufficient consultation and confirmation of precautions are necessary before the procedure.
Which is better, Thermage FLX or Oligio X?
Both devices are Lifting & Tightening devices that use monopolar RF, but which one is more suitable depends on the individual's skin condition and treatment goals.
We recommend checking your skin condition first rather than focusing on the device name, and then making a decision after thorough consultation with medical staff.
Is a pre-treatment skin measurement essential?
Measuring and analyzing skin condition in advance can help design appropriate intensity and focus areas more precisely, thereby reducing the risk of side effects.
Since it is a treatment that involves cost and time, it is good to check whether a pre-treatment skin analysis process is in place.

Recovery and Downtime: What to Expect
Radiofrequency (monopolar RF) Lifting & Tightening treatments like Thermage FLX and Oligio X use thermal stimulation, so temporary redness, heat sensation, numbness, and mild swelling may occur immediately after the procedure.
(※ These reactions generally subside within a few days, but recovery patterns vary individually depending on skin condition and treatment intensity.)
Since it is not a Surgery involving incisions or threads, return to daily life is generally known to be relatively quick. However, on the day of the procedure, it is helpful to avoid strong heat or stimulation (sauna, strenuous exercise, excessive massage, etc.) and pay attention to moisturizing and sun protection.
Rarely, burns or pigment changes have been reported, so if unusual reactions persist, we recommend seeking medical examination rather than self-diagnosis.
How is the cost structured?
The cost of Thermage FLX is not a single fixed price but is determined by several factors.
The composition varies depending on the treatment area (whether it's the entire face or a part), the areas to focus on and the degree of sagging, whether pre-treatment skin measurement and analysis are included, and whether post-treatment care is also considered.
The combination of Thermage FLX, Oligio X, and Ultherapy also influences the cost.
Therefore, rather than simply applying the prices found online, it is more accurate to check your skin condition and then determine what is included in the quoted price.
We recommend receiving an accurate cost estimate after skin measurement and consultation.
