Even though tattooing ourselves has been around since almost the beginning of man, we still don't know exactly how to heal all of it properly.
We know the basics of infection control, certainly.
However, healing a tattoo a certain way to make it look it's best for the longest period of time, has been trial and error.
Some say don't put anything on it at all, go natural and let your body take care of it. Others will tell you to use this or that, it's the only way to do it.
Wrap it, don't wrap it. Lots of suggestions out there.
My best advice is to listen to your tattooist. They have experience with their work, the type of ink they chose to use, and their customers, and they will suggest what has worked best for them, and what "might" work for you.
Edit...Seems I've only repeated what SCT has said while I was typing, I am going to leave my answer though, because I believe the advice is worth repeating, even at the expense of me looking rather silly.
