I can help you with the Garnier ad . . . I don't have a copy, but it was shown when Charlie Brooker did an advertising special on his Screenwipe programme, and the ad is on Youtube
here (it appears for a few seconds at 3:24, including the nipple moment, but the whole episode is worth watching - it's one of the funniest programmes on British telly).
I don't remember this Boots ad (although it sounds pretty cool) but I do have questions about a couple of other British ads. I remember seeing one once for Holland & Barratt, the healthfood stores, which had people walking around a supermarket naked (holding special offer signs in front of their bits) but which never seemed to appear again. I also remember a lot of fuss in the papers at around the same time about a 'risque' campaign for After Eight mints, where people stripped off after a posh dinner party. I never saw it, so I don't know if it was any good or not. These are going back a while; seven or eight years at least. Anyone have any clues?
