I have seen some tattoos gone bad. In some cases the tattoos were done in unsanitary conditions. Believe it or not, there are people who think it is okay to do the procedure at home in the family garage.
Anyway, once you get a tattoo it is important that you clean the area regularly. Don't just put a bandage on the tattoo and leave it covered for days. As a rule, you should wash your new tattoo three to five times a day until the wound is fully healed. Also, apply moisturizer if needed.
