"After a few years of Neosporin being the #1 product recommended for tattoo aftercare, it soon became apparent that it was falling short of its expectations. Several people were coming up with allergic reactions to the ointment, and were getting tiny red bumps on their tattoos. After these red bumps disappeared, they took the ink along with them and the customer was left with a "spotted" tattoo.
This is why many artists now will also recommend A&D ointment as an alternative to Bacitracin. A&D is not anti-bacterial, but it does contain two crucial ingredients, obviously - Vitamins A and D. These vitamins are very good at healing abrasions and minor wounds because they keep the skin supple and protected from outside organisms. The downfall with this product is that because it does not include any actual healing agents, it is not going to help you if you are prone to infection. Most people really don't have to worry about this, though - as long as a tattoo is kept clean and protected, infection fighting ointments are really more of a precaution than a necessity."
Do A&D the first few days as it heals, maybe twice a day, and then put lotion on it as much as possible for the following weeks.
