Concealer
Cover up those face tats for that job interview.

I think it would be cool to build on the existing, subtler disguise methods of wigs and cosmetics with a kind of "concealer" makeup. All this would really do is hide any tattoo @nakeds on the body part it's applied to, until it's washed off (or smudges, maybe?)

I've definitely wanted something like this in the past - cover up that face naked with a bit of makeup so you're not immediately recognized. Maybe it could change your skin color a bit, too.
