When sebum builds up on the nose, it stands out and doesn't cover up with makeup, so it's constantly bothersome. You want to pop it out, but it doesn't work well, and even if you do, the pores just get bigger, making it easy to end up with a strawberry nose. However, this product is great because it is very easy to use and doesn't damage your nose. As you can see in the picture, if you apply a warm steam towel to your nose before using it, the sebum comes right out.
