Preliminary experiences with lasers in the treatment of tattoos over a period of more than three years have shown that this is a safe procedure, both for the patient and for the operating personnel, when conducted in specially designed laboratories and with planned safety programs. The laser treatment of tattoos is still, and will continue to be for some time, an investigative treatment and not a conventional treatment.
