FutureDerm has posted an article entitled "5 reasons you need a Clarisonic ARIA brush system
". In it they claim that it can reduce the formation of blackheads because it oscillates 300 times per second. Now I'm not quite sure what oscillation is or how it relates to blackheads, but the clinical study that the site is linking to redirects me to a search form where I find nothing related to Clarisonic. I then found this PDF
in which there are numerous additional claims. Can the Clarisonic ARIA brush really do all they claim? I'm especially interested in the blackhead claim.
