title: Tattoo removal by overtattooing with tannic acid.
abstract: Removal of tattoos was studied in the guinea pig. Professional tattoos were made, and two different solutions of tannic acid were injected intradermally into the tattoos four times. The macroscopic end result was formation of a slight fibrosis with little visible pigment. Histologic examination after treatment showed a moderate fibrosis with little visible pigment situated deeper in the dermis than in the untreated tattoo.
