Blackhead Pore Packs

The renovation in our house has caused lots of dust. Sleeping in a tiny room cramped with our dusty furniture doesn't quite help either and I've seen some new spots appearing on my face and blackheads on my nose! My facial is long overdue as I haven't had time to do one in a while! Perhaps it's time I ran out to buy a bottle of facial scrub to get rid of my nose blackheads or one of those funky pore pack things which claim to lift blackheads from your pores. Anyone ever tried one before? Does it work?
