Without going to professional. Been there a couple of times and its too expensive. Anyways....my I squeeze the pores on my cheeks I can see small string of grease coming out. The pores are pretty big and I can see that there is crap inside them. I cannot squeeze every single pore. Besides my face gets a big swollen after I do it. What can I do to eventually have clear skin? I usually use proactiv as my cleanser.
