Keep the bandage on for approximately one hour, and no more than six.
Once you remove the bandage, wash it every 4 hours with antibacterial soap (never dish soap)
Some use A&D ointment but I never have and in most cases, you don't need to.
After 4 days, begin applying unscented lotion. I use lubriderm but curel works equally well. Any good unscented lotion will do.
Your new tattoo is going to produce plasma. A pussy clear fluid that looks like it is seeping. That is normal.
If you don't wash your new tattoo it will get infected and ruined, so washing is the most important step.
Never put any petroleum based creams like carmex on it. Petroleum jelly holds in germs and will cause your tattoo to become infected.
Do not expose your tattoo to excessive sunlight for at least a month. After, make sure you use a good, high SPF sunblock on your tattoo or the colors will fade.
Now the biggest thing. Do NOT pick the scabs. Or scratch at your tattoo. You will damage it!.
If it is on your back, you may want to get some non stick gauze and cover your new tattoo at night. This will prevent it from sticking to your clothes of sheets while you are sleeping. In the morning, make sure you wet the bandage, so as to make sure you don't pull the ink or scabbing off.
Your tattoo needs to breathe as much as possible. So, when you can, uncover it and allow it to get as much air as possible.
