With me the aftercare depends on who is tattooing me. Usually its
Remove wrapping as soon as I get home
Wash with hot water and anti-bacterial soap.
Pat gently with a clean paper towel and air dry for a good 40 minutes
Apply a thin layer of Aquaphor. As thin as possible
Repeat twice a day.
Day 4-5 start applying E45.
Normally the tattoo wil start to flake by day 5 and by day 7 its more or less healed. However if the tattooer has a bit of a heavy hand I have found that if I apply Aquaphor it causes heavy scabbing, even after washing and drying very carefully. So I leave out the Aquaphor. It takes a bit longer to heal about 10 or so days.
