Review (1/5): Does not work
I purchased this at local department store. After purchasing the clerk said, "this is a really concentrated formula so you just need a tiny bit on the dark spot and you are not going to start seeing results until the bottle is almost gone." I thought to myself, "ok, so what you are saying is it doesn't work." Anyway, lesson learned. I have one pretty large sun spot on my cheek. I applied as directed morning and night and have been doing so for about 3 months. I see no difference. If you have to use the entire bottle before seeing results, well that could take a year especially if you are just using a tiny bit as directed. Waste of money. I have seen results using Clinique dark spot eraser.
