Bacitracin is my preference, I give three packs to each customer. I tell ’em they can switch to Lubiderm after a week if they want. NO NEOSPORIN! It tends to draw the pigment out… not good. A&D is okay. No Vaseline or any petroleum based product. Regular hand lotion will work in a pinch, and be sure not to let it get too much sun. Don’t let the shower run directly on it either. Tattoo Goo or TatWax is good too, but pricey. Tat Numb or Deaden is good, and has benzocaine in it to keep pain to a minimum, but it’s about eight dollars wholesale and most shops don’t stock it. Deaden can be used during your tattoo sitting, and my customers tell me it helps a lot. Enjoy your new tattoo! Thanks.
