I had a similar reaction to bio oil.
Just about the only thing I can use on my skin at the moment is sorbelene.
I have standard sorbelene I buy for $3 odd bucks at Aldi for a litre and one that the chemist makes up himself, has some vitamin stuff in it I think and olive oil, it has a sorbelene base.

Maybe you could go to your local chemist and see if they do something similar. It literally fixed my really dry itchy skin up almost straight away.
It's still dry but well on the way to recovery and I don't look like an ape when I am out and about from constantly scratching.
