Re: silly question about UD primer
Mine doesn't have an odor (I don't think -- or I haven't noticed it since I'm not paying much attention). On me it's a barely-there colour when I apply it (I am of a darker complexion, by the way). You're only supposed to use a little, little bit and it's true, a little really does goes a long way.
UDPP is my HG allover eyeshadow base. I don't know how I lived without it.
