I know a lot of topical products claim to get rid of blackheads, but it's totally illogical. Blackheads develop a hard top to them that not even the harshest of ointments and what have you can break through. I'd suggest that you have a long, hot shower to soften the skin on your face (or you can steam your face by carefully leaning your face 20cm over a bowl of just-boiled water for 5 - 10 minutes with a towel over your head to trap the steam), then pat your skin dry and sanitise your hands. Take a clean bobby pin and use the eye of it to gently squeeze around the blackhead, supporting the area underneath with your thumb. When it has been emptied, sanitise the bobby pin and continue the process until you've gotten rid of as many as you can. This process shouldn't hurt. If it does, you're damaging your skin and thus need to stop. When you're finished, take a clean cotton pad with some toner on it and sweep it over your nose. This will soothe the area and remove any dirt or whatnot from the surface of your skin. You don't need to use the bobby pin method every day by any means; 1 - 2 times a fortnight sounds about right. Always make sure your hands are sanitised, or else you're risking the spreading of bacteria. One more thing I'd like to add in is that those blackhead strips you see do not work. Your nose has lots of tiny little hairs growing from the surface (known as "peach fuzz"; present all over the face), and these blackhead strips are ultimately waxing these off your nose which can cause future problems with the hair growth by retarding the follicle, causing some of the hairs to become ingrown.
