View pricesDo any of these acne-scar or skin concerns apply to you?
Although the color tone is subdued, the unevenness becomes a shadow depending on the angle of the light.
This may be due to hardened scar tissue or adhesions under the skin.
Even for the same "acne scars", the treatment suitable for them differs depending on the depth, shape, and strength of adhesion.
What is TriFill Pro?
This is an acne scar/scar treatment device that performs "microsubcision" and "drug injection" at the same time.
Carbon dioxide gas is injected through the needle tip to release firm scar tissue and adhesions horizontally in the shallow layers of the skin. Medications such as Juvelook are delivered to the created microscopic spaces.
It is unique in that it can locally work on the tissue that is causing the dent, while injecting the drug that supports skin reconstruction into the same location.
- You can choose the Treatment area from shallow irregularities to individual scars.
- Delivering drugs to a space created with carbon dioxide gas
- Gas amount and drug amount can be adjusted according to skin condition
How TriFill Pro works
The needle remains in position while three steps—release, delivery, and dispersion—are performed in sequence.
TriFill Pro in video
You can see the flow of microsubcision using carbon dioxide gas and drug injection in the device introduction video on the original page.
Release adhesions with carbon dioxide gas
Carbon dioxide gas is injected into the dermis to release scar tissue and adhesions horizontally within the shallow dermis.
Deliver medication
A drug such as Juvelook is injected into the space created by the exfoliation.
Disperse the medication
The carbon dioxide gas spreads the drug around, delivering it evenly to the layer you want to treat.
Two treatment methods
One mode treats a broader area, while the other targets individual depressions.
Even with the same device, you can use it differently depending on your skin concerns.
Drug delivery
Carbon dioxide gas and Juvelook are evenly injected into the skin to correct a wide Treatment area of textures such as pores, shallow unevenness, and lack of firmness.

How TriFill Pro fits into acne-scar treatment
Rather than treating every depression with one treatment, the roles are divided according to the depth and Treatment area of the target.
| Treatment | Main target Treatment area | Characteristics of treatment | Suitable problems |
|---|---|---|---|
| TriFill Pro | Shallow dermis/local to whole face | Microsubcision + drug injection with carbon dioxide gas | Shallow irregularities, local adhesions, pores, skin texture |
| Manual subcision | Deeper subcutaneous plane | Remove deep and hard adhesions with needles and cannulas | Deep rolling depression, strong retraction |
| Potenza | Wide Treatment area | Microneedle RF works on the entire skin | Pores and skin texture, shallow unevenness, and redness |
If you have active acne, we will combine anti-inflammatory treatments with scar treatment.

Frequently asked questions about TriFill Pro
Which acne scars is TriFill Pro suitable for?
Acne scars that have shallow irregularities that spread out, or acne scars that have been pulled in due to local adhesion are candidates for treatment. Deep depressions may be combined with other methods, such as manual subcision.
Is there any pain during the treatment?
You may feel pain when the needle is inserted or when carbon dioxide gas or medicine is injected. Topical anesthesia is used depending on the treatment area and mode.
What downtime can I expect?
Redness, swelling, bruising, and needle marks may occur. The extent and duration vary depending on the treatment area and skin condition. Makeup can usually be applied from the next day.
How many sessions may be needed?
As this is a treatment that takes time to rebuild the skin, we may recommend three or more treatments, approximately once a month. For local scars, adjust the number of treatments while checking the depth and size.
What is the difference with Potenza?
Potenza uses radiofrequency energy delivered through the needle tips to work on a wide Treatment area of skin types and pores. TriFill Pro differs in that it uses carbon dioxide gas to peel off shallow adhesions and delivers the drug to the created space.
Can I receive treatment even if I have active acne?
You can consult us. However, we may avoid treatment on areas with strong inflammation and recommend treatment to calm down the acne inflammation first.
Determine the depth of the dent,
Treat where you need it.
Acne scars vary in depth and shape even on the same cheek. Whether the goal is to improve overall skin texture, or do you want to prioritize the dents that will become shadows? We will listen to your wishes and downtime and suggest the order of treatment.
