TCA CROSS for boxcar scars

Boxcar scars are depressions with relatively defined edges, but they are not all alike. Some are narrow and deep; others are wider with a flatter base. TCA CROSS delivers concentrated acid into selected scar points to stimulate repair within the depression. It cannot rebuild every scar in the same way, and it does not erase active acne or prevent new scars. A close examination helps separate boxcar scars from rolling or ice-pick scars and identifies whether one technique can address the main texture concern.

Book an assessment rather than choosing treatment from a photograph or attempting acid application yourself. Discuss active breakouts, picking, previous pigment changes, cold sores, eczema, and any medicines that affect healing. Your clinician may recommend treating acne first or combining scar approaches at different visits. After treatment, keep the area clean as instructed, let crusts detach naturally, avoid irritating products, and use sun protection when advised. Improvement is usually judged over the healing period, not on the day of treatment.

Call the clinic about escalating pain, spreading redness, pus, fever, or swelling that does not follow the expected course. Urgent care is needed for eye symptoms, breathing difficulty, swallowing difficulty, or extensive blistering. Persistent redness, a new dark or pale patch, or a raised scar should be examined rather than treated with another product at home.

Ask which scars are boxcar scars, which ones are suitable for TCA CROSS, what alternatives exist for broad depressions, and how progress will be assessed.
