TCA CROSS for Icepick Scars

How it works

A high-concentration trichloroacetic acid is applied with a fine applicator tip to the base of an individual icepick or boxcar scar. The acid causes a controlled local injury, and as it heals the body builds new collagen that may raise the scar base. A small dark crust forms and falls away over about a week. Improvement is gradual, usually needs several sessions and varies by person.

Who it may suit

• Icepick scars that lasers do not reach well
• Narrow, deep boxcar scars
• People who can accept small crusts for about a week
• Those willing to repeat the treatment over months

The treatment day

1. Scar mapping. The doctor identifies which scars are suitable, checks your skin tone and asks about keloids and isotretinoin use.
2. Skin preparation. The skin is cleaned and degreased so the acid acts evenly.
3. Acid application. A small amount of acid is placed on each scar until a brief white frosting appears. Stinging is common.
4. Aftercare briefing. You are told to expect small dark crusts and given written care instructions.

Aftercare

• Do not pick the small crusts, which fall off in about a week
• Keep the area clean and moisturized as advised
• Use sunscreen daily to reduce the risk of dark marks
• Avoid scrubs and strong actives until healed
• Report spreading redness, pus or enlarging marks

Things to know first

• Stinging, redness and dark crusts for about five to seven days are expected
• Post-inflammatory darkening can occur, especially on darker skin or with sun exposure
• Excess acid or poor technique can widen a scar or cause a new one
• Care is needed around isotretinoin use, keloid tendency, active infection and pregnancy
• Improvement is gradual, varies by person, and several sessions are typical

What to check before booking TCA CROSS in Gangnam

Ask who applies the acid, and how experienced they are with this specific technique. Precision at the scar base is what keeps the acid from spreading to healthy skin, so this is a task for a trained physician, not a general beauty step. Ask whether they have a protocol for different scar widths, since a stronger acid is not automatically better and the choice should be explained.

Ask about the acid itself: its concentration, how it is prepared and whether it comes from a labelled medical supply. A clinic should be willing to tell you what percentage will be used on your face and why. Ask also about your risk: a careful doctor considers your skin tone, sun exposure, any scarring tendency and recent medications before starting, and may begin with a conservative strength.

A clear quote lists the number of sessions, areas treated and follow-up, and does not promise fully smooth skin. Be skeptical of claims that TCA CROSS removes scars outright. Honest advice presents it as one tool for deep narrow scars, often combined with other methods, and sets expectations of gradual improvement over several months.
