Trichloroacetic acid (TCA)

Trichloroacetic acid (TCA) is mostly used for superficial as well as medium depth peel. In order to maximize the effects and overcome complications such as scarring and pigmentary changes that can occur with deep chemical peels, focal application of TCA, restricted to the atrophic scars has been conducted. The technique called CROSS. Chemical Reconstruction Of Skin Scars is a technique using high concentrations of trichloroacetic acid focally on atrophic acne scars to induce inflammation followed by collagenisation. This can lead to reduction in the appearance of scars and cosmetic improvement.
