I have such a hard time with pore strips, they never work for me, these were the first ones that I could actually see things on the strip after pulling it off! Each step does say to wait about 15-20min but it is definitely worth the wait! 

I have tried a bunch of different pore strips and am always highly disappointed when it doesn't pull up and gunk from my nose, but I was so amazed at everything this 3 step black head solution pulled up! I already placed an order for more <3 

Pretty good, will buy again!
