user "savitor" said "DO NOT use anything with extra healing in it" which is good advice because you want a tattoo to heal naturally, but just keep it moist. this is the reason why using neosporin, contrary to popular belief is not a good idea. yes, some people will get fine results with such things, but there is no point in chancing it. speeding up the healing process may cause scabbing which may lead to minor scars and color fall out.
anyway, aquaphor is good to use, as well as A+D ointment. they are both very similar. i'm not sure why your artist told you not to use it and to just use lotion, even tho i sometimes do that myself out of laziness, but i get my tattoos for free, which means free touch-ups so it doesn't bother me, heh. one thing that bothers me about not using any sort of ointment for those crutial first 3-5 days is that lotion will not suffice in keeping a fresh tattoo moist. your skin reacts to lotion entirely different unhealed then it would if it was closer to healing after a week. instead of keeping it moist, it will most likely be absorbed too quickly, or simply not absorbed at all, and rub off, if that makes any sense. ointment in a thin layer is good because it will penetrate the surface while still allowing the skin to breathe if applied properly.
as far as which lotion to use, it goes into what i was saying before, i wouldn't use anything with healing properties, even though this is most likely refering to the "healing" of dried cracked skin and probably doesn't literally have healing ingredients in it, but i can't say for sure, i don't have a bottle in front of me. so pretty much anything scent free like you said (and yeah i've seemed to notice that they DO smell good anyway) but it's all good.
you seem like you know what you're doing, it's very refreshing, a lot of people are clueless when it comes to tattoo aftercare. i have a quick basic care sheet on my website if you'd like to take a look at it. http://www.refugeink.com just go to the main page and just scroll down in the little window in the middle of the page. i'm not the guy on the front, that's my best friend, i'm the other artist nik.
good luck!
