If it's an option, see a dermatologist.
Seriously, I know it might seem like overkill - but if it's something you're able to do, they can really help you out with the products you're using. Removing blackheads can actually be tricky, and a lot of the time, if you extract them improperly, you're just pushing some of the gunk further into your skin and that will cause more problems.
Blackheads are really tricky. Once you remove them, it doesn't matter how big or small your pores are, if you leave the pore open, you'll just collect more oil, sweat, dirt in it and BOOM another blackhead. The trick is to have them removed, and then fill the pore with something good for your skin. Like a really good moisturiser, something with healing stuff like vitamin E in it. That way, you aren't leaving the pore open to be clogged up again. Hope that helps! smile
