Quick Warning:  When using this product, use your head and keep in mind that it is a hand cleaner and is not a proven acne cleaner.  If it was, they would jack up the price from $17.01 for a 10 lb container to $17.01 for a 2 ounce container.  This product has worked for me personally, however I only use it once or twice a week.  The pumice is pretty harsh on your skin, so I would only recommend it for those with very oily skin, like myself.   If you have normal or dry skin, this product will probably damage your skin.  You can get a small bottle of this stuff for only $2.00 ,  so if you are interested, test an inch sized area on your face.  You should know pretty soon if it will work for you or not.  If it DOES work for you without any any bad reactions, use it max twice a week.  The rest of the week, use your normal cleaner.  Think of this product as something to rejuvenate your skin on occasion, NOT a replacement cleaner.
