My friend put liquid glue on hers, then when it dried peeled it off. She says it's convenient and inexpensive, but idk if it really works, she shows up with clear skin. You should give it a try. (But make sure no one is around, i thought it was pretty weird when i saw her put it on the first time)
Well i'm not sure this works but use face soup everyday... it works for me with pimples and stuff. but i'm pretty sure in the shops theres some face masks and stuff for black heads. Hope this helps... sorry if it doesn't.
There are nose peels you can use. They work very well! You can buy them pretty much everywhere. I've also found that face scrubs work, but you should only use it on your face before you go to bed! Otherwise, it dries out your skin and opens the pores, which let more dirt and stuff clog them.
