What is TCA Cross?
TCA Cross (Chemical Reconstruction of Skin Scars) is a targeted technique using high-concentration trichloroacetic acid (TCA, typically 70–100%) applied precisely to the base of individual acne scars — most commonly ice pick scars and narrow boxcar scars. The acid triggers a controlled wound healing response that fills the scar from the bottom up.
Treatment is highly targeted, taking 15 to 30 minutes per session. A series of 3 to 6 sessions spaced 4 to 8 weeks apart is typically needed for best results. Downtime per session is minimal — treated spots form small crusts that resolve within 5 to 7 days.
TCA Cross is considered one of the most effective targeted treatments for ice pick and narrow acne scars and is often combined with microneedling, fraxel, or subcision for a comprehensive scar revision protocol.
How much does TCA Cross cost?
TCA Cross nationally typically costs between $200 and $800 per session depending on the number of scars treated.

What to ask your provider
- Am I a good candidate — do I have primarily ice pick or narrow boxcar scars?
- What concentration of TCA do you use, and how does that affect results and downtime?
- How many sessions do you recommend for my scar pattern?
- Will you combine TCA Cross with other treatments (microneedling, subcision)?
- What does post-treatment care look like — can I wear makeup, go in the sun?
- What is your experience level with TCA Cross, and how many treatments do you perform monthly?
