Natural Scrubs - Salt vs Sugar

I've been experimenting with creating my own of scrubs with essential oils and vitamin e. Scrubs are very easy to make with little cost. There are tons of natural recipes on-line DIY if you want to make your own. I'm still struggling with salt vs sugar? Personally, I do prefer salt scrubs because I like the consistency of the batter for exfoliation. Here is one of my favorite hot salt scrubs is Philosophy Senorita Margarita (the smell is lovely) found locally at Sephora.
