I was first introduced to Tropic body smooth when I received a sample in my Jolie Box beauty box I get every month. I absolutely loved it so put it on my birthday list and got it :) hehe. Because I use fake tan ALOT I feel my skin can dry out and even exfoliating is harsh on the skin. Tropic body smooth has a oil in it so you mix it in with the salt and apply it to you body so it oils your skins and exfoliates , the results are amazing, as soon as you wash the salt off your skin is sooooo smooth, I really can't describe how good this product is and it actually does what it says on the tin!!
