 The new device Eraser TM uses multiple needles action with a washing fluid to remove tattoos. Healthy patients who wish to remove a tattoo will be enrolled. The study will test the removal of a small part of the tattoo 5cm2 area. Treatment lasts about 20 minutes with local analgesia if needed, after which an absorptive bandage is put over the treated area for an hour and removed. Treatment may be performed using one of two washing fluids. For one of them, blood samples for material blood level will be taken before and several times after treatment. Pictures of the tattooed area being removed will be taken before and after treatment, and at each follow-up evaluation.
