Could a Nivea-Guinness Merger be on the cards?

Is drunkenness good for the skin?

I know, you might think this a random question, but really it's the cheeriest thought I've had all day.

We all - aside from my charming hostess who points out that there's no conclusive scientific evidence on this point - know water's good for the skin, don't we? And we never drink quite so much water as when we're hungover, do we? Therefore, surely, hangovers are good for the skin, and so the alcohol that forges our hangovers must in turn be good for us.

I realise there's a flaw in the logic there somewhere, but I'm not feeling very virtuous at the moment, so give me a break.
