TCA CROSS stands for Trichloroacetic Acid Chemical Reconstruction of Skin Scarring. It is used to improve the appearance of poral like scars and acne scars that are either ice pick, punch out or box like.
The TCA concentration used can vary from 80-100% and multiple treatment sessions are necessary for optimal results. In darker skin types, post inflammatory hyperpigmentation (PIH) is common, but this will resolve after some time.
The treated scars may look slightly worse when the scabs fall off and this may sometimes be the case at the beginning. One treatment generally improves the scar by 20-40%. But we are unlikely to achieve complete scar removal with this treatment method alone.
TCA CROSS is well tolerated and is generally done without any anesthesia. A test treatment is advisable before we embark on full face treatment.
After applying the TCA, the skin turns frosty white just in the small treated area. 2-4 days later, tiny scabs would form over the treated area and the time frame varies from person to person. After about 5-7 days, the scabs will fall off.
There will be redness, which will last a few weeks. Some small scars or dilated pores can be completely gone after a single CROSS. The multiple tiny scars will be gradually filling in over the ensuing weeks.
TCA CROSS treatment is often repeated at 30-60 days apart and 5 sessions or more are recommended.
