in gr8, i had to do science fair with this girl..and she said her sister buys nail polish/cosmetics from the dollar store..(no name brand ones) her sister didn't have any rashes or stuff on her face..so i guess its fine..but i wouldnt do it because i have really sensitive skin, even to neutrogena face wash!

it doesnt hurt to try, make eup has no actual expiry date, i suppose leaving them around for 3-4 years max is okay
