Hello, I’m Im Young-soo, the chief director of Troy Plastic Surgery.
Today, among those who clicked on this post, there are probably many who have concerns like these.
“Even though I had Ultherapy, why does my face look exactly the same as before?”
“Am I the only one who doesn’t see any effect?”

Especially as people age and begin to feel skin sagging and reduced elasticity, many make the difficult decision to undergo Ultherapy but feel disappointed and confused when they do not get the results they wanted.
In fact, our clinic also hears this concern from quite a few patients.
So today, for your valuable time and peace of mind, I would like to speak honestly from a medical perspective about the real reasons why some people feel Ultherapy does not work in the Mok-dong area, and the answers to those concerns.
Reason 1. A matter of treatment intensity depending on skin type
Reason 2. A matter of setting the correct ultrasound depth
Reason 3. The importance of using genuine devices and tips
Reason 4. Individual lifestyle habits and aftercare
★ Tips to increase satisfaction with Ultherapy
Reason 1. A matter of treatment intensity depending on skin type
Ultherapy uses powerful ultrasound energy to act on the SMAS layer, the deepest layer of the skin, in order to achieve a lifting effect.

However, because skin thickness and the degree of aging differ from person to person, simply using a higher intensity does not necessarily produce better results.
For example, if the skin is thin and sensitive, treating it with too much intensity may only irritate the skin and make it difficult to achieve the desired level of firmness improvement.
On the other hand, for thicker skin, the treatment must be performed at the correct depth with relatively higher energy in order to see results.

Therefore, before treatment, it is most important to accurately diagnose your skin condition and set the energy and depth accordingly.
Reason 2. A matter of setting the correct ultrasound depth
Ultherapy works when the ultrasound reaches the SMAS layer accurately.
If the ultrasound energy is not delivered precisely to the SMAS layer, the effect may be minimal or may not appear at all.

The SMAS layer is located at a depth of 4.5 mm
Even when actually using an ultrasound device, slight differences in angle or how closely the device adheres to the skin surface can change the depth and accuracy of ultrasound delivery.
Therefore, experienced medical staff must finely adjust the treatment depth to match each patient’s skin condition.
Reason 3. The importance of using genuine devices and tips
Ultherapy requires the use of genuine devices and genuine tips to accurately deliver ultrasound energy to the deeper layers of the skin.
If counterfeit tips or unverified devices are used, the output and delivery of the ultrasound may be inconsistent, making it difficult to feel the effects after treatment.
In fact, among dermatology specialists, there is a common view that the results of Ultherapy can differ significantly depending on whether genuine products are used.
Therefore, when choosing a clinic, it is a good idea to check in advance whether genuine devices are being used.
Reason 4. Individual lifestyle habits and aftercare
Ultherapy is important for its immediate effects, but care after the procedure also affects the results.
Proper skin moisturizing, sun protection, and maintaining healthy lifestyle habits after the procedure have a major impact on how long the treatment effect lasts.
In particular, smoking, excessive drinking, and irregular lifestyle habits can slow skin regeneration after the procedure and reduce the expected effect.
Therefore, if you have undergone Ultherapy, you should pay even more attention to your skin care than usual.
★ Tips to increase satisfaction with Ultherapy
- Get an accurate skin diagnosis
Before an ultrasound procedure, it is important to have your skin condition professionally assessed and to establish a treatment plan.
- Confirm the use of genuine devices
Before the procedure, you should make it a habit to check whether the equipment and tips being used are genuine.
- Thorough aftercare
Sun protection, moisturizing care, and a regular lifestyle are essential for skin recovery and for maintaining the effects of the procedure.

Final advice
If Ultherapy did not work for you, I hope you will not be discouraged and think that your skin cannot improve.
Ultherapy is a procedure that delivers the best results only when accurate diagnosis, the correct treatment method, and thorough aftercare all work together.

We will always be medical staff who listen sincerely to your skin concerns.
Thank you.
