Ultherapy Prime, from effects to changes over time

Ultherapy Prime lifting, is it really effective?
Have you ever looked closely at your jawline after taking a photo? There comes a time when you feel your facial contours aren't what they used to be, even if you haven't gained weight. If you look up Ultherapy Prime (the procedure often called Ultherapy), you'll find reviews saying "it definitely made a difference" right next to reviews saying "I don't see much of a difference."
Both reviews can be true. This is because Ultherapy Prime is not a procedure that shows immediate results right after you leave. Knowing what changes and when it happens can help align your expectations with the results.
Why is there no immediate change after the procedure?
Ultherapy Prime is not a procedure that physically pulls the skin up, but one that stimulates the skin to produce collagen on its own.
By delivering ultrasound energy to deep layers rather than the skin surface to create tiny thermal coagulation points, our body produces new collagen in the process of recovering those points. It takes time for that collagen to settle. Therefore, changes appear not on the day of the procedure, but several weeks later.

The key here is the SMAS layer. This is the layer actually pulled during a facelift in plastic surgery. Ultherapy Prime sends energy to this layer via ultrasound without cutting the skin. This is why it is used to improve sagging.
Grace Dermatology (Haeundae, Busan) uses Ultherapy Prime equipment and adjusts the depth while checking the layers with ultrasound imaging during the procedure.
How is it different from threads or Botox?
The three have different purposes.
– Thread lifting — Physically hooks and pulls. Changes are visible immediately.
– Botox — Reduces muscle movement. Involved in wrinkles and contours.
– Ultherapy Prime — Stimulates the skin to restore elasticity on its own. Appears slowly.
If you "want to look different right now," Ultherapy Prime alone might be disappointing, but if you want a "natural, gradual lift," it is a good fit. Which one is right for you depends on the degree of sagging, so it is determined during the consultation.
When will I feel it, and how long will it last?
This is the part most people are curious about. The flow is roughly like this.

There is almost no swelling on the day of the procedure, so you can return to daily life immediately. Substantial changes usually start to be felt around 4 weeks later and are often most noticeable around 3 months. The duration varies by individual, but it is generally reported to be 6 months to 1 year.
The important thing is the month after the procedure. Some people get disappointed thinking "did I just waste my money?" and stop their care, but the collagen is still being produced. You can wait a little longer.
Representative Director Kim Tae-hoon sets the number of shots and intensity by area after diagnosing skin thickness and the degree of sagging. This is because the results vary depending on where and how much is used, even with the same equipment.
How is it different from Thermage?
The two procedures are not in competition; they target different concerns.

If your concern is a sagging jawline, Ultherapy Prime is more suitable; if you feel your skin is thinning and losing elasticity, Thermage is closer. It is common to have both concerns, so you can choose one or consult about combining them during the visit.
These people receive it often
– People in their 30s-40s whose jawline or cheeks have started to sag
– Those who find surgical lifting burdensome but want to start care
– Those who cannot take time off for recovery and need to return to daily life on the same day
However, if the sagging is quite advanced, you may not feel as much change as you expected with Ultherapy Prime alone. In such cases, it is better to consider other methods, and we will be honest about this during the consultation.
Frequently Asked Questions
Ultherapy Prime Is it effective even if I get it only once?
Collagen regeneration is induced even with a single session. However, if there is sagging, we may recommend re-treatment every 6 months to 1 year, which is decided individually through consultation.
How long does the procedure take?
It varies by area, but it takes about 30-40 minutes for the entire face. To alleviate pain, a topical anesthetic cream is applied first.
Is it very painful?
Ultherapy Prime has pain relief features, so it can be performed relatively comfortably. However, since individual sensitivity varies, we use anesthetic cream and cooling devices together.
Does it leave swelling or bruising?
There is usually no noticeable swelling, and occasionally, minor bruising or redness may appear for 1-2 days. The recovery period is short, so you can return to daily life on the day of the procedure.
How is it different from Thermage?
Thermage stimulates collagen in the dermis with radiofrequency, while Ultherapy Prime reaches the deeper SMAS layer with ultrasound, focusing on improving sagging. At Grace Dermatology, we consult on choosing one of the two devices or combining them depending on your skin condition.
Who is this procedure especially suitable for?
It is suitable for people in their 30s-40s who have started to experience sagging jawlines or cheeks, or those who feel burdened by surgical lifting. It is safe to determine the exact applicability after a consultation with a dermatologist.
Ultherapy Prime is a procedure that you "have to wait for" rather than one that "changes you as soon as you get it." Knowing this alone will change your satisfaction. Please check if it is the right method for your skin during the consultation.
