TCA CROSS for Acne Scars in Seoul, Korea

TCA CROSS is a highly targeted acne-scar revision procedure where a high-concentration solution of Trichloroacetic Acid (TCA) is applied directly into each individual atrophic acne scar (especially ice-pick and boxcar types) to stimulate collagen remodeling and improve skin texture.
The “CROSS” stands for “Chemical Reconstruction of Skin Scars”. The method focuses on the base of the scar, causing a controlled injury that triggers new collagen formation and lifts the depressed scar.
It is especially useful for deep narrow scars that are resistant to surface treatments or lasers alone.

Seoul has dermatology/aesthetic clinics that offer TCA CROSS as part of their advanced scar-revision services—many mention it explicitly in their acne scar menus.
The cost in Korea tends to be more affordable (compared to many Western markets) and multiple sessions or packages are available.
Because you are based in Gyeonggi-do (near Seoul), you have convenient access for consultations, treatment sessions and follow-up visits if needed.

Consultation & assessment

The dermatologist will evaluate your scar type (ice pick, boxcar, rolling), skin condition, skin type/colour and any underlying acne activity. Understanding scar morphology is key to deciding if TCA CROSS is appropriate.
They will discuss the number of sessions required (often multiple), expected downtime, risk of pigmentation, and after-care.

Treatment day

The area is cleaned and a high-strength TCA (often 50-100%) is applied directly into each scar using a fine applicator (such as a toothpick or micro-needle).
The solution causes a localized “frosting” or scab formation within 1-2 days. dermatologyseoul.com+1
Duration: Depending on number of scars, may take 20-40 minutes or more for full face if many scars.

After-care & recovery

The treated scars may form crusts/scabs which typically fall off in ~5-7 days. dermatologyseoul.com
Redness, slight swelling or discoloration may persist for a few days. Collagen remodeling continues for weeks to months, and visible improvement becomes more evident over time.
Multiple sessions are often needed (usually 3-5 sessions spaced around 4-8 weeks) for best results.

Particularly effective for deep narrow scars such as ice-pick scars and some boxcar scars.
Improves texture by stimulating new collagen at the base of the scar, leading to smoother skin contour.
Compared to some ablative laser treatments, TCA CROSS can sometimes be more direct and targeted for certain scar types (though not a complete substitute for all scar types).

Good candidates:

Individuals with well-defined atrophic acne scars (especially ice-pick or boxcar) who have relatively stable skin and no uncontrolled active acne.
Those who are willing to commit to multiple sessions and follow-up care.

Consider alternatives or combination approaches if:

If your main concern is rolling scars with tethering or significant skin laxity rather than narrow deep scars – then subcision + filler + laser might be required.
If you have very dark skin tone or melanin-rich skin—and are concerned about risk of post-inflammatory hyperpigmentation or hypopigmentation. In such cases, you must ensure the clinic has experience treating darker skin tones with TCA CROSS safely.
If you expect immediate dramatic results—TCA CROSS shows gradual improvement and rarely eradicates scars fully in one session.

One data point lists the cost of TCA CROSS in Korea (chemical peel component) as approx ₩50,000 – ₩100,000 KRW for the procedure fee (plus solution cost) in some clinics.
Another resource lists acne scar treatments (including TCA CROSS) starting in USD ~ $75-185 (~₩100,000-₩250,000) for specific peel/targeted scar treatments.
Given that comprehensive scar revision often uses multiple methods, full package costs can be significantly higher (laser + TCA + microneedling). Be sure to check exactly what the quote covers.

For dark skin/skin prone to pigmentation: What protocols will you use to minimise pigment risk?

Before treatment:
Avoid active acne flares; ensure skin is as stable as possible.
Use sun protection diligently in the weeks leading up to treatment.
Avoid any strong chemical peels or treatments just before your session.
On the day:
Arrive with clean face (no heavy makeup).
Ask about numbing options (if sensitive).
After treatment:
Expect some micro-crusting at each treated scar site; follow the clinic’s instructions on cleansing/ointment.
Avoid picking scabs; maintain gentle skincare.
Use good sunscreen to protect treated areas from pigment risk.
Avoid strong exfoliants or aggressive treatments until skin is fully healed.
Monitor for any unexpected reactions (persistent redness, pigmentation changes) and report them.
Maintenance:
Book your recommended subsequent sessions (2-4 additional sessions often).
Combine with other methods if needed (e.g., microneedling, laser) for best outcome.
Maintain skin health (sleep, nutrition, sun-protection, gentle skincare) to help collagen regeneration.
