Biore deep cleansing pore strips are great to use on your skin. I purchased the nose strips to use on myself. I have used these several times and I am always happy with the results of them. You get eight strips per package. I bought these at Wal-Mart by the facial cleansers. They cost around $6.00 for this package, which is very reasonable to me.
These strips basically pull all of the dirt out of your pores. You simply wash your nose off and then wet it. You open up the package and pull the strip off of the plastic. You place it on your nose pushing it down with the smooth side against your nose. The strip is supposed to stay on for 10-15 minutes. It starts to get really hard and reminds me of paper mache. I usually leave it on until it feels hard which is around 10 minutes for me. Then you peel it off of your nose.
Once you take it off your nose will feel a bit sticky. I always just wet a rag with water and wipe it off. That gets the sticky part right off. You can look at the strip and see the stuff it got out of your pores. It will be covered in dirt that it got from your nose. This is gross, but shows you that it did a good job!
I would highly recommend this product. They actually make them for your forehead, chin, and other parts of your face as well. I have tried all of these, but feel like I need the nose ones most so this is all I usually buy. You can get a variety pack that has all of them in it. I think they are worth the price. You are supposed to use them about once a week, but I usually wait two weeks between applications myself.
