Try using a retinoid at night. That *might* alleviate it a bit. 

I have that on my cheeks and forehead, but I don't know how to get rid of it either. :/

I've read only a dermatologist can extract those. I've been to a dermatologist to ask about it and he said "You can't do anything about it." I highly doubt that and think he just wanted me out of there. :/ Maybe someone can do extraction on those when you get a facial?

Some sort of gentle exfoliation can help. They're probably clogged pores. Try adding baking soda to your cleanser and using that occasionally, or a retinoid, or some sort of chemical exfoliant. Also, if it's only on your forehead, it might be from a hair product? Try switching hair products.
