Finally had a reply back from them:
Thank you for your enquiry regarding copyright. Please note that I am unable to provide you with any legal advice, however I hope the following information is of use.
The general rule of copyright ownership is that the creator/author of the work is the first owner of the copyright in the work.
Photographs, under section 4(2) of the Copyright, Designs and Patents Act 1988, are classed as artistic works. Therefore, if you take a photograph you own the copyright in the artistic work (unless you take the picture in the course of employment or some other contractual agreement). This includes taking a picture of somebody or something in public; they would have no copyright rights over the photograph.
Brand named groceries may afford both copyright and more likely trade mark protection. For example, the images/ artwork on the can of baked beans could be protected as an artistic work, and the brand name 'Heinz' is a registered Trade Mark.
According to section 63 of the Act, it is not an infringement of an artistic work to copy it, or to issue copies to the public, for the purpose of advertising the sale of the work.
Trademark law as such does not restrict the use of a trademark in a photograph. However it does forbid someone using a trademark in a way that can cause confusion regarding the affiliation of the trademark owner to the image.
If consumers are likely to mistakenly believe that a photograph was sponsored by the trademark owner, then there may be trademark infringement.

I hope this is of some assistance.

I've highlighted the bits that probably cause the most confusion - I guess that both of these would be down to the interpretation of the judge if the product owner every decided to sue, but I suspect that the case would be thrown out if you were a legitimate supplier.
However, if you have obtained your product via a dubious, non-official stockist, then you might be in trouble - it was in the trade mags this week that Dermalogica have been successful in getting Boots to withdraw Dermalogica products which they obtained from a supplier overseas.
Hope this helps and clears it all up - sorry it has taken a while.
