LOL!!! It doesn't look fake to me. If you really look at both pictures, the packing is really similar. I think the second picture is just the updated packaging. I just looked at mine and mine looks just like the second one, but it has the 33% more on the top like the first. That mask should be for real.
I will say that the picture from your auction says it is only 2oz. I bought mine at Walgreens for $3.49 and it is 8oz. Just so you know for price comparison. It is pretty cheap stuff. So I wouldn't pay lots of money for just a 2oz tube.
