I think the facepaint is probably a tattoo. For the reasons Cerryd observed plus it just seems kind of weird to have to paint such an elaborate symbol on your face every day.
Well, you wouldn't need to reapply a henna tattoo every day. As for there still being bluish markings around Garrus' scar, I've already noticed that his wound looked like layers of skin got peeled off in places (it looks that way around his mouth, especially), so if only some skin got peeled off, I'm pretty sure a henna tattoo would still be partially visible as well.
Hmm, I just thought of an interesting application for bareface turians. Couldn't they paint their faces as whatever and possibly be effective spies or something? In fact, it seems that having permament facepaint would almost limite turian in some ways. Do you think some turians change their facepaint to game the system somehow?
If it's a real tattoo, it's probably super complicated to have it changed. If it is some form of semi-permanent paint, then there would be more flexibility as to what they could do with it.
