Yeah i got blackheads on my nose and chin and even when i squeeze them they dont seem to go anywhere, there are these white strips you can buy that you peel like a band aid. You put it on the area where there are blackheads, the strip needs to be wet then it eventually drys then you pull it off like you would pull of a wax strip. iit soaks the blackhead juices and actually removes them from your skin. It helped me and it may be painful but they wont be there anymore,,,,,,,,if you do this make sure you apply your pimple cream to seal it. Warm water opens your pores and cold water closes it so when you wash your face use warm water to open your pores for a thorough wash
not really any foods or drinks that make them appear or go away.this is a hormone issue.a dermatologist might help.
