"What's the difference if I do both together?"
When I receive this question in a combined consultation, I first talk about the layers.
The two procedures work at different depths.
They don't overlap, which is why they are used together, and because they don't overlap, there are also cases where only one is needed.
Please take just 1 minute to read this.
Different Locations
| Category | Ultherapy | Gouri Booster |
|---|---|---|
| Method | Ultrasound energy delivery | Liquid PCL injection |
| Target | Deep fascial layer | Collagen regeneration in the skin |
| Issues addressed | Sagging due to relaxation of supporting structures | Skin texture degradation, feeling of thinning |
| Perceived effect | Lines and contour | Skin texture and thickness |
Sagging occurs when the supporting strength from below weakens, and skin texture degradation occurs when the skin itself becomes thin and sparse.
Since the causes are different, the areas approached are also different.
Cases Where Both Are Recommended
This is when both problems exist simultaneously.
A typical example is when the jawline has collapsed, and the skin itself is thin and has a rough texture.
In such cases, if only sagging is addressed, the lines may be refined, but the skin still looks tired. If only the skin texture is addressed, the skin may improve, but the contour remains the same.
Approaching each layer separately can lead to a change in the overall impression.
(※ Effects and reactions may vary depending on the individual's skin condition, and suitability for the procedure is determined through consultation with medical staff.)
Cases Where a Single Procedure Is Better
- When sagging is clear, and skin texture is maintained.
- When skin texture degradation is the main problem, and the lines have not yet collapsed.
- When there is a schedule that requires a short recovery period.
Combination is not always the better choice.
Touching layers that are not currently needed only increases the burden of recovery and cost.
Order and Timing
If proceeding together, decide whether to do them on the same day or separately.
Deep layer procedures can leave a dull ache, and injection-based procedures can cause swelling and bruising, so reactions may be amplified if done on the same day.
If there is ample time in the schedule, sometimes the sagging treatment is done first, and after recovery, the skin texture treatment is performed.
The topic of aging varying by layer was covered in Aging does not happen in one layer.
Frequently Asked Questions
What is the difference between the two procedures?
Ultherapy uses ultrasound to target the deep fascial layer, while Gouri Booster uses liquid PCL injection to regenerate collagen within the skin. They act on different layers.
Do I have to receive both?
It can be advantageous when sagging and skin texture degradation occur together. If only one is an issue, a single procedure may be sufficient.
Can they be done on the same day?
It is possible in some cases, but recovery reactions may be amplified. If you have ample time in your schedule, it may be more comfortable to separate them.
Is there a specific order?
Sometimes, the sagging treatment is performed first, and after recovery, the skin texture treatment is performed. The order is determined based on your condition and schedule.
What are the post-procedure reactions like?
Deep layer procedures may cause a dull ache, and injection-based procedures may result in swelling and bruising. The degree and duration can vary individually.
Recovery and Downtime: When Two Reactions Overlap
If done individually, each typically subsides within a few days.
If done together on the same day, the perceived recovery period may be longer.
Both procedures show changes over several weeks, so it is advisable not to judge the results immediately after.
How is the cost structured?
The cost is not determined solely by the sum of the two procedures.
It varies depending on the area and number of shots for each, the injection volume and number of sessions, and whether diagnosis and post-care are included.
For an accurate cost, it is best to provide guidance after a consultation to assess the proportion of sagging and skin texture degradation.
Visit and Consultation Information
O.N Clinic is conveniently located near Gangnam Station, making it easily accessible by subway.
Before your visit, you can comfortably inquire about any questions you have by chatting now for a consultation, and through the consultation, you can coordinate the combination, order, and appointment schedule.
It is more accurate to determine whether a single or combined procedure is suitable after checking the condition of each layer during an in-person consultation.
