Ah the fingernails ... i find this the most puzzling aspect of P. Mine can be dreadful when my skin is fine or perfect when my skin is awful. I do find that keeping my hands adequately moisturised is also helpful (I keep some on my desk, in my handbag, in the kitchen ... basically dotted around everywhere I might be ... I like neutrogena )
I do find that making sure that I take the Barney's formula with Vitamin D helps to manage them ... but sometimes I just get frustrated and slap some nail varnish on them to hide the problem. Not a long term solution unfortunately and I'm pretty sure doesn't make it any better.
