I'm surprised at L'Occitane, not surprised at their claim but surprised that it actually was printed in English! In France it seems that you can make pretty much any claim on your product, I've translated loads of nonsense miracle claims from big French corporations and there is even at least one 'eau minceur' - slimming water! However when translating we always had to put in words to soften any claims, so instead of a slimming cream it was a cream which appeared or seemed to make you feel slimmer, it really opened my eyes to false advertising, there are entire product ranges of things like skin care based on flowers which don't even exist! We always had to send our translations to be approved by lawyers in the US though, to ensure that no false claims were made, so I'm surprised that it appears that L'Occitane didn't!
