TCA Peel in Seoul: Medium-Depth Renewal and Scar Care
The short answer
A TCA peel uses trichloroacetic acid to remove the outer skin layers and stimulate collagen, improving pigmentation, fine lines, rough texture and some acne scars. In Gangnam a full-face medium TCA peel typically costs about ₩200,000–₩600,000, while focal TCA CROSS for icepick scars costs about ₩100,000–₩400,000. Expect 5–7 days of darkening and peeling, with 1–3 sessions spaced 6–8 weeks apart.
Key facts
- Acid: trichloroacetic acid, typically 10–35% for peels, higher for TCA CROSS
- Treats: sun damage, pigmentation, fine lines, rough texture, icepick scars
- Session time: 30–45 minutes
- Downtime: 5–7 days of darkening, tightness and peeling
- Sessions: typically 1–3, every 6–8 weeks
- Typical Seoul price: about ₩200,000–₩600,000 full face
- Key risk: post-inflammatory pigmentation in darker skin
What makes a TCA peel different
Trichloroacetic acid works differently from fruit acids like glycolic acid. Rather than loosening cells, it coagulates proteins in the skin, creating a controlled, uniform injury. As that layer peels away, the skin regenerates with smoother texture, more even pigment and increased collagen in the upper dermis. Strength determines depth: lower concentrations act as superficial peels, while 20–35% creates a medium-depth peel with more noticeable results and recovery.
Because TCA penetrates more deeply, it is always applied by a doctor in Seoul clinics, with careful timing and observation of how the skin "frosts" to judge depth.
What it treats
- Sun damage, freckles and some uneven pigmentation
- Fine lines, especially around the eyes and mouth
- Rough, uneven texture
- Mild acne scarring and enlarged pores
- Icepick and narrow boxcar scars, using the TCA CROSS technique
TCA CROSS for acne scars
CROSS stands for Chemical Reconstruction of Skin Scars. Instead of covering the whole face, the doctor applies a very high concentration of TCA precisely into the base of individual narrow scars using a fine applicator. This causes focal inflammation and collagen production that gradually raises the scar floor. It is one of the most effective tools for icepick scars, which respond poorly to many lasers. Usually several sessions are needed, six to eight weeks apart. For broader scar plans, see our scar remodeling guide.
TCA compared with other peels and resurfacing
| Treatment | Depth | Downtime | Main use |
|---|---|---|---|
| Superficial AHA/BHA peel | Superficial | 1–3 days | Acne, dullness |
| TCA peel | Medium | 5–7 days | Pigment, lines, texture |
| TCA CROSS | Focal, deep | 5–7 days small scabs | Icepick scars |
| CO2 laser | Ablative fractional | 5–7 days | Scars, wrinkles |
Preparation
Your doctor may ask you to use a mild retinoid or brightening cream for a few weeks beforehand to prepare the skin, stop it several days before the peel, and avoid tanning. If you have a history of cold sores, antiviral medication is usually started. Tell the doctor about any recent isotretinoin, keloid tendency or pigment problems.
The treatment
The face is thoroughly cleansed and degreased. TCA is applied in even layers while the doctor watches the skin turn white, a sign called frosting that indicates depth. You will feel strong heat and stinging for a few minutes, eased by cooling fans and compresses. The skin feels tight and looks slightly swollen afterwards. A soothing ointment is applied before you leave.
Recovery day by day
- Days 1–2: redness, tightness and mild swelling
- Days 2–4: skin darkens and feels leathery
- Days 4–7: peeling in sheets, revealing pink new skin
- Weeks 2–4: pinkness fades and texture improves
Keep the skin moisturised with a bland ointment, avoid sun completely and never pull at peeling skin. Makeup can usually be worn after peeling ends.
Pigment safety for Asian skin
Medium-depth peels carry a real risk of post-inflammatory hyperpigmentation in Asian and darker skin, often appearing two to four weeks after treatment. Korean dermatologists reduce this risk with conservative strengths, skin preparation and diligent aftercare. Temporary pigmentation generally fades over months with brightening care and sun protection. Discuss this risk openly before treatment, especially if you have melasma.
Planning as a visitor
Allow at least a week in Seoul after a TCA peel, with a follow-up visit before you fly. Avoid trips to sunny destinations straight after. Ask the clinic which concentration will be used, whether it is a full-face peel or focal CROSS, and what aftercare is provided. Our scar revision treatments guide compares other options.
