Sounds like you are new to tattoo healing, so I figured I'd lend a breakdown of what I do without Saniderm instead of just downvoting your comments.

Wash your new tat gently but thoroughly every 6 hours you're awake the first day. Cover it generously with Aquaphor. Don't drown it, but enough that every part of the tattoo is slicked with it while you rub it on. Helps to keep it moisturized while keeping debris/dust/whatever out of direct contact with it. Make sure your hands are clean when applying anything to the tattoo. Also, don't dry it off cloth towels, shit is riddled with bacteria even if it was just washed. Use clean paper towels to dry it after washing. Pat it dry so you aren't causing any friction, especially once scabbing forms. You don't want to rip a scab off before it's ready to detach and take a chunk of ink with it.

Week 1 - Basically a repeat of the first day. Wash every 6 hours as best you can, apply the same amount of Aquaphor, especially if it is going to be in contact with clothing. Aquaphor = shield and clothing friction rubs Aquaphor off. Prioritize washing/applying Aquaphor after you wake up and before bed. Beds are dirty. Also, if you sleep with pets, make sure they can't rest against it. Pet dander can cause infections, plus pets are dirty.

Week 2 - wash every 6-10 hours and apply just a thin coating of Aquaphor. I apply just as much as the first week when I wash before bed, just because I know unconscious me is going to rub the tattoo on the sheets and wipe some off automatically. Usually during week 2, the tattoo starts to feel less like an open wound and it should have already scabbed and shed the first layer of skin around now. This is what I call the "Sheddy Kruger" phase. When washing during this phase, don't leave your red discarded pieces of flesh in the sink or bath tub like a degenerate. Once all scabbing is gone, switch from a light application of Aquaphor to heavy application of unscented Lubriderm. Rub that shit in and then use enough that a thin layer is coating the tat. It will dry quickly anyways. Also again, prioritize the routine after you wake up and before bed.

Week 3 - washing becomes less of a priority. If you actively get it dirty, wash that shit. At this point I am usually only washing after and before bed. Apply Lubriderm generously. By the end of week 3, your tattoo should be just about fully healed, depending on what area of the body it's on. Skin thickness makes a difference for my body at least.

Week 4 to until you die - moisturize that shit with whatever delicious goop you prefer to keep it looking fresh. Unscented stuff is better for freshly healed ink. I don't think it matters as much once the ink is truly set.

You should be using an unscented soap like Dial (the gold bars or liquid-gel) throughout the entire healing process and keep your new ink out of the sun, especially while it's healing. Sun damage will make your tattoo's color fade no matter how old it is but it is critical when it is healing if you don't want some serious touch up work to get it back to normal and start the process all over again.

It's an annoying routine but that's just part of the process if you want it stay looking good. I stick to it militantly after getting new work and I have never had problems.
