Clogged pores!

Savannah
I'm wondering if anyone has a suggestion for the problem I'm having. I've never had an issue like this before but I've got a million of these things on my face now for the past few months. It's not pimples the only way I can describe it is clogged pores, when you squeeze them it's just white stuff that comes out. They're especially concentrated on either side of my chin and even underneath my jaw. I've tried every type of pore unclogging cleanser anyone makes it seems. I've also been using a cleansing face brush that runs on batteries. I've tried masks, too. I wash my face twice a day. Anyone else have this problem and what helped you?
