I'll tell you that there are a lot of things that can be wrong with buying beauty products from someone you cannot trust. you could make yourself ill, or damage your skin. You are probably getting very old product at the very least. The stuff could be used, opened, or tampered with. These are products you are basically putting into your body, using on your eyes, ect. I would be very careful about buying any skin care or cosmetics online. This authenticity thread is a good idea. But, none of us can tell how old the product is, unless it's obviously very old, outdated packaging. What a shame there are so many fakes and scammers out there!
