摘要:
This study was designed to investigate whether trichloroacetic acid (TCA) peeling induces cellular proliferation in human skin using an immunohistochemical method. A 40% TCA peel resulted in a greater number of proliferating cell nuclear antigen (PCNA)-immunopositive cells in the whole epidermis as compared with 60% TCA or phenol peels. This finding suggests that long-term and frequent TCA peelings of low concentration would require special attention for unexpected cutaneous lesions such as skin tumors.
