Researchers in France, Sandrine HENRI and Bernard MALISSEN, Inserm and CNRS researchers at the Centre d’Immunologie de Marseille-Luminy (CIML), have discovered that, though a tattoo may be forever, the skin cells that carry the tattoo pigment are not. Instead, the researchers say, the cells can pass on the pigment to new cells when they die. The study, which will be published 2018, March, 6th in the Journal of Experimental Medicine, suggests ways to improve the ability of laser surgery to remove unwanted tattoos.
