I just used this stuff- I took a steamy shower, washed my face and then followed the instructions stating to get the cotton ball REALLY wet when applying Silver Powder- then I laid flat and let it dry. Next I used a pore strip and as I pulled it off, I literally did not have a black head in sight. I have battled blackheads my entire teenage and adult life. This product is INCREDIBLE... I seriously cried. I am going to use it weekly and can afford to do so, it's a reasonable price. Try this if your blackheads give you grief.
