Pores enlarge and texture roughens when dermal collagen thins and stops supporting the pore walls. Trifill PRO opens the space under the dermis with pressurized CO₂ gas and injects Olidia myo (PLLA) evenly into it so collagen rebuilds. Red and brown marks left by acne fade as blood flow recovers and the dermis regenerates, and pitted scars and stretch marks are treated the same way with the adhesion released as well. Gas, solution and gas, all in one shot.
Trifill PRO is a CO₂ subcision and drug delivery system developed by MCURE. Instead of scraping adhesions with a needle as in manual subcision, it releases the tissue under the skin with pressurized CO₂ gas and, within the same shot, injects a regenerative solution precisely into the released space and spreads it evenly with a second burst of gas. At Dr. NewCell that solution is Olidia myo, a PLLA collagen stimulator, which restores dermal density: across the whole dermis for enlarged pores and rough texture, and into the released floor for pitted scars.
Pores, texture and acne marks are the most common Trifill PRO consultations at Dr. NewCell, followed by pitted scars and stretch marks. In every case the cause is in the dermis.
Pores and scars share one cause: the dermis
Pores enlarge and texture roughens when dermal collagen density falls and no longer supports the pore walls; pitted scars and stretch marks add a fibrous band that holds the surface down. Treatments that heat from above refine the surface but leave dermal density and that band untouched. Trifill PRO works from below.
When collagen fibers in the dermis break and adhere, the surface sinks. Trifill PRO fills the space beneath in the order gas → solution → gas. 3D mechanism segment from the manufacturer's (MCURE) promotional video (no sound).
CO₂ enters beneath the dermis and opens a space; where there is a scar it also detaches the fibrous band. Wider and more even than needle subcision by hand.
Before the space closes, Olidia myo goes precisely into that layer. Placing it evenly in the intended layer helps reduce the chance of lumps (nodules).
A second burst of gas disperses the solution across the dermis around the pores. New collagen then supports the pore walls and fills the scar floor.
Evidence
The manufacturer injected dye into porcine skin to compare methods. With the same volume, injection after CO₂ subcision spreads wide and even, while hand subcision or a plain injection pools at one point. For a treatment that must reach the dermis around every pore and the whole scar floor evenly, this difference decides the result.
| Study | Subjects · method | Findings |
|---|---|---|
| Chin et al., Ann Plast Surg 2013 | 34 patients with facial wrinkles, intradermal CO₂ followed by sequential HA, 3–11 month follow-up | Dermis 1.6× thicker 12 months after CO₂ alone (2.64 vs 1.62 mm). CO₂ + HA dermis 1.9× thicker than HA alone (4.21 vs 2.19 mm). 91% highly satisfied |
| Koutná, Aesthetic Medicine 2011 | Carboxytherapy protocols by indication | Atrophic scars: 2–6 sessions 3–4 weeks apart, "very good". Deep scars need the fibrous strands under the scar destroyed. Stretch marks 2–4 weeks apart, "good" |
| Zelenková, Glob Dermatol 2017 | Mechanism and clinical experience | CO₂ lowers tissue pH, increasing oxygen release (Bohr effect) and blood flow. Pain is momentary; small bruises in some cases. Change usually within 7–14 days after two sessions |
The literature supports CO₂ gas injection itself and the sequential injection of a regenerative substance after CO₂. Trifill PRO is the device that performs that sequence automatically in one shot.
Different concerns, different tools
Enlarged pores and rough texture call for PLLA spread widely through the whole dermis. Pitted acne scars are classified by shape as ice pick, boxcar or rolling, and each responds differently. Trifill PRO suits pores and texture, and rolling and boxcar scars where adhesion is the cause, best; narrow ice pick scars are combined with other treatments.
Find yours
Even with the same Trifill PRO, how the shots are placed and what it is combined with change depending on whether your concern is pores, scars or marks. Pick what bothers you most right now and we will show how Dr. NewCell plans Trifill PRO for it. The final plan is set together with the doctor after examining your skin in person.
We pass over the whole cheek once with 20% overlap, filling the dermis widely and evenly with Olidia myo (PLLA). From four to eight weeks, as collagen builds, pores and texture begin to change.
PLLA spread across the whole dermisSee how it works →The doctor presses each scar to classify it, then places one shot at a time where adhesion is the cause, detaching the fibrous band and filling the floor. Narrow ice pick scars are planned as a combination rather than alone.
Releasing adhesion in rolling · boxcar scarsSee fit by scar type →Trifill PRO supports blood-flow recovery and dermal regeneration, and any remaining redness and texture are finished with Rejuran or skin boosters. Dark brown marks get a pigment laser as well.
Blood-flow recovery + dermal regenerationSee combinations →Trifill PRO first rebuilds dermal density and the depth of pits; four weeks later Potenza refines pore openings and surface texture. Filling the dermis first helps the results of the surface treatment hold steadily.
Dermis first, surface nextSee combinations →Grooves that stay folded at rest and stretch marks are released and filled on the same principle. Lines made by movement are handled with Botox, with two weeks between treatments on the same area. For stretch marks, the number of sessions is planned to suit their condition.
Stretch marks · static linesSee fit by concern →It does not stimulate the surface with heat, so no crusts form. Injection marks and redness settle in one to two days. You can wash gently the same day and wear makeup from the next day.
Not a heat-based treatmentSee what to expect →These are example plans by concern, not a diagnosis. The number and spacing of sessions and any combined treatments are decided in consultation after looking at your skin and scars.
Laser · microneedle RF · subcision · Trifill PRO
Dr. NewCell runs Potenza (microneedle RF) and Trifill PRO together. Potenza provides heat stimulation at the surface; Trifill PRO rebuilds dermal collagen density and releases adhesion. For pores and texture, using the two in order lasts longest.
Treatment characteristics are based on general operating principles and manufacturer data; results and downtime vary with the scar and the treatment plan. Which treatment suits you is decided after the doctor examines the scar type in consultation.
Release is immediate, filling takes time
The release of adhesion shows at once; the collagen PLLA builds fills in over weeks. That is why the second session is scheduled four weeks later.
Gas and solution fill the space under the dermis so the skin around the pores feels firmer, and scars become shallower as the adhesion detaches. Injection marks, redness and slight swelling are present.
Redness and swelling subside. Washing and makeup are fine from the next day.
New collagen forms around the PLLA; pores begin to look tighter and texture smoother. The second session is done at four weeks.
Collagen production continues after the course, pores and texture hold, scar depth softens, and the PLLA gradually breaks down and leaves nothing behind.
After release and fill
Olidia myo clinical cases. Scar cases were photographed after two sessions four weeks apart.
Results vary with scar depth, adhesion and lifestyle; these cases do not appear identically in every patient. Photos: Olidia myo manufacturer (K.P BIO) clinical cases, published with patient consent.
Dermis with Trifill PRO, surface with Potenza
Pores, texture and scars have causes in more than one layer, so we combine treatments layer by layer in a set order. We rebuild dermal density and lift depth first, then deal with surface texture, pore openings and red marks in order.
Trifill PRO rebuilds dermal collagen density first; four weeks later Potenza refines pore openings and surface texture. Filling the dermis first helps the results of the surface treatment hold steadily. If pitted scars are present, the adhesion is released in the same sequence.
Trifill PRO lightens the marks through blood-flow recovery and dermal regeneration; remaining redness and texture are finished with Rejuran or skin boosters. Dark brown marks get a pigment laser as well. Can be done the same day, Trifill PRO first.
Lines made by movement get Botox; grooves that stay folded at rest are released and filled with Trifill PRO. The same area is spaced two weeks apart.
If the scarred cheek has started to sag, Trifill PRO fixes the depth first, then Alltite lifts firmness and the line across the whole dermis. See Alltite lifting
Process
Which layer to fill, how much, and where to release shape the result. That is why the doctor handles everything in person, from reading your pores, texture and scar type in consultation to the treatment itself.
Seated, the doctor checks pore laxity and texture, then presses each scar to tell rolling, boxcar, ice pick and stretch marks apart and marks where adhesion is the cause.
Topical anesthetic, then cleansing. No injected or sedation anesthesia.
The handpiece is placed vertically on the skin; suction holds it and gas, solution and gas go in automatically. Pores and texture: the whole cheek in one pass with 20% overlap; scars: one shot each.
You see the shallower pits in the mirror together, then decide on the second session in four weeks and any combination such as Potenza.

FAQ
For international patients
Trifill PRO tightens enlarged pores and smooths rough texture by filling the dermis with PLLA (Olidia myo) after opening it with CO₂ gas, and repairs pitted acne scars and stretch marks by releasing the adhesion underneath. Two to three sessions four weeks apart are ideal; if you can visit only once, we plan the first session in Seoul and follow your progress by LINE or email.
トリフィルプロは、CO₂ガスで真皮の下に空間を作りPLLA（オリディアマヨ）を注入して毛穴・キメを整え、ニキビ跡・妊娠線は下の癒着まで剥離する治療です。4週間隔2〜3回が理想ですが、1回のみの来院でも初回を行い、帰国後はLINEで経過を確認します。
