The salt scrub can be used for all skin types.  Instead of an enzyme or acidic action to remove dead cells, the salt scrub uses a mechanical action.  The salt scrub is the easiest and best way to have a scrub available at all times.

All you have to do is simply add salt to your cleanser or soap.  It is very important you do not add salt to the product in the bottle or jar.  You must only add it at the time of cleansing or you will change the chemical constituency of the product!!  You can also do the exact same thing with sugar.
