Well I've done lots of reading on all the after care products but I've only ever used Bepanthen. I know it does contain a petroleum product but every one of my tattoos has healed brilliantly and only one had a very small scar (due to the artist going over a spot too many times).
I'd like to try Aquaphor but just don't want to risk it, if it ain't broke don't fix it, I guess.
