Trichloroacetic acid is a commonly utilized agent for chemical resurfacing of the face. Trichloroacetic acid is a metabolite of trichloroethylene thought to contribute to its hepatocarcinogenic effects in mice[1][2].
Trichloroacetic acid (TCA) is a common drinking water disinfection byproduct that produces a spectrum of liver effects, including hepatomegaly and liver tumors, in mice. It is also an oxidative metabolite of trichloroethylene (TCE), a solvent used in degreasing with widespread environmental exposure, which also produces hepatomegaly and liver tumors in mice[3].
