It depends on the scar. Personally, I tend to scar up really bad, it gets raised and red and whatnot. That would make the tattoo look weird probably. But less intense scars, like old ones that aren't as raised, aren't red (usually more like a tan color) wouldn't really effect the tattoo at all. There are some artists that won't tattoo over a scar, so you should ask that question first before anything else.
