does not work [SEP] 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 does not 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 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
