Depths of Chemexfoliation Induced by Various Concentrations and Application Techniques of Trichloroacetic Acid in a Porcine Model

Abstract

The depth of wounds created by various concentrations and application techniques of trichloroacetic acid (TCA) in a porcine model is evaluated. The depth of tissue necrosis increased with the concentration of TCA. Tape occlusion did not deepen the wound but rather decreased its depth. An inverse relationship of wound depth to epidermal thickness is described.
