This used to be a great product [SEP] Now it's no longer made or sold.  Don't fall for their new "resurfacer" volcanic ash crap for $66.  You can smear it all over your face and I promise you it does nothing.  Senederm used to have great products at higher but reasonable prices.  The products don't deliver and the prices are way too much.  Your money will be better spent on another brand I promise.
