Something to think about
I've been using this product for well over a year.  I only use it once a day and my blackhead pores are smaller but it does not rid blackheads.  There is still material in the pores, so don't expect a miracle.  The one thing I can add is this product can cause some serious inflammation to skin that does not need to be treated.  I always get a little overlap on my cheeks and under my eyes and try to wash it off right away, but if this is left on for the five minutes in application and wait time, my skin almost blistered and it took months to get the skin area close to my eye back to normal.  Just a heads-up.  You may not have this problem but it is definitely a problem for me.  I apply this product now with a Q-Tip and am extremely careful that I don't touch areas of my skin that do not need this product.  I'm pretty hyperconscious about it now.
