Does makeup cause aging

Well, this is hard to determine. First of all it depends on what makeup your referring (lipstick, blush, foundation, eyeliner?), the formulation, and the way in which it's used. Not to mention there have never been formal studies conducted on this, however to be honest I'd say the right answer is a big fat NO. Makeup can make you break out, and poorly applied makeup can make you look older, but if you wear a non-comedogenic base, and apply it well it shouldn't age you, not to mention if it has SPF it'll actually prevent aging .
