When I first used this product I didn't see any improvement on my blackhead or pores. It felt like this didn't even do anything.After a while what I did notice is that although it didn't get rid of my blackheads it has prevented new ones from appearing. I've done a facial mask and a nose strip that cleared a lot of my blackheads. Then I've been using this product morning and night and the blackheads doesn't seem to be returning. I would say this product is okay for preventing new ones.
