Maybe a product with glycolic acid? I just ordered this glycolic peel. It says it's not for sensitive skin, but if IIRC, I think some of the people who reviewed it on MUA had sensitive skin and said it didn't bother them.
REN Glycolactic Skin Renewal Peel.
Otherwise, I think salicylic acid is supposed to be good at getting rid of blackheads.

I use Queen Helene Mint Julep mask. It clears up my nose and cheeks without drying out my skin or clogging the pores. You can get it at any drugstore for about $4.
I would recommend Astara Blue Flame Mask. It's a tea tree oil/clay based mask that can be used as s pot treatment or all over mask. I woudl do that whenever you have a specific spot that you want to treat, and I would use M.D.Formulations Daily Peel Pads every night before bed. The Peel Pads are dual sided, and they're made up of a glycolic compound, which is a mix of salycilic acid and glycolic acid. I personally react terribly to anything with salycilic acid, and I have never had a problem with these. I use them on my hairline where my hair prodicts build up and break my out, and also on my chest where my sports bra traps sweat and gives me a nice little breakout.
