What you should never do is lubricate it with Sperti. That's bad for a tattoo and he does not get prettier. The tip to rub him with udder ointment is not good. In udder ointment is namely petroleum that can fade the color of the tattoo right. You can when he is cured rub it much better with Nivea body lotion or body lotion that is not strongly scented. And otherwise just enjoy using the ointment from the tattoo studio.
