Cool cool. So how often did the tattooist recommend you apply cream, and how often do you actually do it? I don't mean specifically the hands, because they're probably one of the easier and less uncomfortable places to do so.
Also have you gotten all these done at the same place? I had a friend who swore by the one artist (and had many done), but it didn't really click with me that he didn't have any coloured ones until another friend was all like “yo no tha's a bad idea dawg” so I called up and just got the outline done for now. The first place I went was five years ago in Dublin and I was pretty happy with that but the place has since shut up shop, so that's sad.
Edit: Actually they just moved, so that's not so sad.
