I purchased this item and recently recieved it in the mail.  THIS REALLY WORKS! I love this product! My skin is already light but have a few tan marks that I wanted to get rid of.  I applied this product and voila! Made my skintone pale - love it.  The bottle is fairly large.  You honestly don't need to use too much of the product for it to work.  I applied a very thin layer left it on about 5 minutes and rinse it off.  It says do not rub off but I would rub under water ever so lightly.  The whitening power lasts for almost the entire day.  You won't be disappointed.  It works! Also I don't recommend using this on your face.
