I wasn't quite sure about this tool in the beginning, but after using it for several weeks, it has become indispensible. it is dead easy to use. It does leaves mark but so do my fingers, it can make your eyes water though and you look like Rudolph when you are done, but if you have annoying black heads this is what you need! It works so much better than the scrubs and you can see results instantly, both on your nose and the little tool itself. Your nose feels so soft and smooth afterwards.
I love it. Highly recommended
