I make many scents of bath salts.  They are hydrating because of the grapeseed oil which helps with dry skin, oily skin and acne.  Its one of the easily absorbed oils for the body and doesn't leave a reside in the tub.  Each package lasts for 4 baths.  Use 1/4 cup or more per bath. The cafe mocha and skittle are my favorite.  The skittles is a mix of orange. lemon and tangerine and smells like the candy.
