Hey peeps! I just had a question for y'all--has anyone had experience with returning an item purchased at Sephora? I've never had to return anything (miraculously ;)), but I just received an order and some of the lip glosses I ordered are all weird and gloopy and look as if they've separated. I checked online and it says to return "unused" items, but...has anyone tried to return something "used", and if so, was it difficult? Would it be easier to return it at a Sephora store? Thanks!
