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?

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. :/

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.

Try eliminating dairy. Some peoples skin reacts from dairy causing little bumps on face. Also make sure your skin care products do not have any fragrance or dyes in them. That could irritate your skin causing bumps.
