These things are awesome for me. I don't have many blackheads, but I do have a ton of oil clogging my pores on my nose. I also have rosacea on my nose and it's a huge problem area all around. I used one of these the other night and I wish I had taken a picture for this review to show what all came out of my nose. It was disgusting and fascinating. It didn't irritate my nose (anymore than it already is I guess) My pores did look way smaller after using. Even though my nose is seemingly always going to be my worst problem area regardless of what I use, I still liked to see that a lot of gunk was extracted and it feels nice to know I found something that really* pulls it all out. Great product! *Edit- I have sensitive skin. The pull off isn't that bad, but I like when its a little tougher to rip off. Makes me feel like it actually did something lol
