Like schmange and Edm say, it's just a case of keeping playing and removing the skin as it flakes, it'll soon harden up again. Filing can work, but I'd recommend you wait until they have hardened up a bit and you can't actually feel much on the tips; guitar's painful enough without inflicting more pain on yourself!

On a side note, I do love that "thunk" you get from those fingers on table tops...
