I recently wore my clear lipglass that I have had for well over a year and it dried my lips out. It was so bad that I think I may have had a allergic reaction to it. I know you are supposed to throw your makeup out every so often (probably more often than I do). Has this happened to anyone else? Do you think the reaction was to the lipglass or the fact that its old. I love my MAC lipglasses but now I'm scared to use them.
