I have spent literally over $4000 in the last 3 years to clean blackheads, pores and get rid of zits. Well, this product is supposed to CLEAN blackheads. Not even close. I bought 2 products that say they do this. Bullspit! I used them, blackheads still have gunk in them. The ivitamin c crap gave my face a nice chemical burn. Yes, that's right, a chemical burn. It also darkened my skin and that will take montgs and months to go away. I wish to God there was a way to fine these lying, greedy people who hawk crappy products THAT DO NOT WORK.Iam sick of wasting my hard earned money. When I sent pics to Murad, I was told the redness and brown spots are normal keep using it. I had to see a dermatologist! There should be some way to fine these liars. Look at my face!
