Use of 27-gauge Tuberculin Syringe for Trichloroacetic Acid Chemical Reconstruction of Skin Scars (TCA-CROSS).

Chemical Reconstruction of Skin Scars (CROSS) is a minimally invasive, safe, and cost effective technique for the management of ice pick acne scars that are otherwise generally resistant to treatment. 100% trichloro acetic acid (TCA) is usually applied using toothpicks and the end point is white discoloration of skin. The concentrated caustic agent quite often spills onto surrounding normal skin leading to superficial burns and post-inflammatory pigmentation. Use of 27-gauge tuberculin syringe gives a much more controlled access to apply TCA leading to better cosmetic outcome and fewer adverse effects.
