Undecided Question

I got a new tattoo and i have a few questions.?

okay, so today i got an orange and yellow starfish, it's very good work as far as i know, there is almost no bleeding (a tiny bit of bleeding at the end of the process), and i had very little info given to me on how to care for it and what to use (the artist was clearly in a small rush to get work done and head home for christmas).

so i did some research and i got the basics of cleaning off the plasma and blood after the bandages are removed, but im not sure of what to use for lotion or why to bother with lotion at all, when i get a nasty scrape or deep wound i just let it heal without any help, never had any problems with infection and what not, so why can't i do the same with my tattoo? it heals in basically the same manner as any other skin wound.
also the only lotions i have are all scented and contain some form of alcohol or colouration, i have no more money and won't have any until after the 28th, so im looking for other things to use, the same goes for antibacterial soap, i ain't got none.

is my tattoo pretty much doomed or is the lotion and antibacterial soaps just for cleaniness' sake, i don't worry about bacteria (my immune system does that) and infections (same for these), i have a past of scarification and i have never had to worry about any infections or fevers, my body is good at fighting those things.

any help for me?

tl;dr, i need to know what to use if i have nothing that is unscented/uncolored, and no money, and if i even need to actually worry about that stuff.
