I have convinced myself that I absolutely NEED a Clarisonic, and I will become a clear-skinned beauty overnight, but I am thrown... which should I go for, and also what's the deal with the plug (Aria particularly) - can you just plug it into a regular uk socket - or shaver socket, or will I need to get an adaptor? (Incidentally am just getting our main ensuite redone, and have requested a shaver socket within the built-in vanity - so would be lovely if Clarisonic just plugged in there..)
