Great product
I love this product. You just have to remember that it will discolor your towel, but it does come out in the wash.

Does it normally look like this?
My friend had me try hers and I absolutely loved it! After only a couple hours I was a couple shades darker which is so helpful ! But when I purchased 2 bottles for myself they came with white dots inside and also browning on the bottles ? Not sure if it means they are damaged or if this is normal?

Beautiful Tan
I first found this lotion when I went to Hawaii. It is alittle pricey but works so well! I order it every year. Oh by the way! Do not use it UNTIL you already have a base tan! Smells wonderful like coffee
