What Is TCA CROSS?

TCA CROSS (Chemical Reconstruction of Skin Scars) is a dermatological technique that uses high-concentration trichloroacetic acid (TCA) applied precisely into deep acne scars to stimulate collagen production. It is especially effective for ice pick and boxcar scars that don’t respond well to lasers or needling alone.

Ideal for:

• Deep, narrow acne scars (ice pick scars)
• Boxcar and enlarged pore-like scars
• Acne-scarred areas not suitable for lasers
• Combination therapy with subcision, PRP, or laser

This targeted chemical peel technique encourages skin regeneration from within while preserving surrounding healthy skin.

Cost of TCA CROSS in Gangnam

Pricing depends on how many scars are treated, the number of sessions needed, and if combined with other acne scar treatments.

Estimated Prices at EGG Skin Clinic:

• TCA CROSS (per session): ₩100,000 – ₩200,000
• TCA CROSS + PRP or PDRN Booster: ₩250,000 – ₩400,000
• TCA CROSS + Subcision or Laser: ₩350,000 – ₩600,000
• Full Acne Scar Package (3–5 sessions): ₩900,000 – ₩1,500,000

Most patients need 2–4 sessions spaced 4–6 weeks apart for optimal improvement.

How the Procedure Works

1. Consultation: A dermatologist evaluates scar type and skin sensitivity.
2. Preparation: Skin is cleansed, and numbing cream may be applied.
3. TCA Application: A tiny amount of TCA (usually 50–100%) is carefully placed inside each scar using a fine applicator.
4. Aftercare: Frosting occurs (white reaction), followed by scabbing and peeling over 5–7 days. Avoid picking or scratching during this time.

Collagen remodeling continues for several weeks, gradually lifting and smoothing scar depressions.
