I have been using retin a and it has done wonders for the blackheads.big pore on and alongside my nose. oddly didn't do as much for the ones on my chin. and it ain't doing a thing for the break outs elsewhere on my face... grrrrr! aside from the blackheads I never had a problem with acne until this fall.
I think before the retin a I tried just about every over the counter product that claimed to zap blackheads, except for the really expensive cosmetic counter stuff. masks, biore strips, lotions, potions, liquids, soaps... i was a complete product whore.

Shortness of money is all that's keeping me reformed in that area...
