Will a Derma Roller actually make my pores small?

I have a massive issue with blackheads and pores and I can't stop picking at them. I've been on tretinoin for three months, no change. Same with salicylic and glcolic acid. I've checked every ingredient I use, nothing's causing them. They're just so big. I read that if I micro needle them it'll act like a wound and make them smaller. Is this true?
