If your tattoo is fairly large and you're worried about scarring, Dr. Anderson said the key is Aquaphor. Both the Aquaphor Baby Wash ($11) and the Aquaphor Healing Ointment ($21) will be helpful for tattoo aftercare. "A moist wound heals quicker, it heals stronger, and it heals with less of a scar," Dr. Anderson explained. "The old adage of 'keep a wound dry, let it breathe!' . . . well, wounds don't have lungs. They don't need to breathe. They need to be kept moist, and the best way to do that is with a little Aquaphor."
