I bought my first Montagne Jeunesse mask from Wal-Mart years ago, and expected little from a $2.00 product, but was surprised at how well it worked to deep clean my pores. It is also self heating & feels good to use. You can get 3 masks out of one 'single use' package, so I make a small hole then save the rest in a zip lock baggie to be used later. (Or split it with my sisters.)
