Because they offered a 90 day return policy - which implies that if it doesn't work, they will refund you the full amount, I stupidly ordered this product with confidence. Not only did it not work, but it made all spots much darker, to the point where I am extremely afraid to go out into the sun. When I attempted to return it, they would only accept un-opened bottles. How would anyone have unopened bottles after 90 days, or even 10 days if you had only bought the one?
Also - if you don't have the original standard post office envelope that it came with, you can't return anything at all.
The internet is completely bogged down with fake beauty review sites - Amazon is one of the only places you can buy a product and feel like you are getting some real idea about it, and I am so thankful that I can actually review this product and warn anyone interested - DON'T BOTHER
