But while they're visually somewhat similar, they differ in price (obviously) and motion. While Clarisonic uses a sonic oscillation system, Olay uses a nonsonic rotating one, making for a completely different experience. I almost prefer the circular massaging action of Olay (it's great for soothing sinus pressure), and the bristles seem to be slightly softer. Not that it's good or bad one way or another, but if you are looking for a super deep cleanser with a ton of power, Clarisonic, which has a heftier, more dynamic feel about it, wins out in this battle. To see the rest of my review, just keep reading.
Both systems have two settings so you can pick between a light or more intense washing. Clarisonic charges on a base, while Olay works on AAs. As far as cleansing goes, I used both side-by-side and really couldn't tell which one gives the smoothest, softest results. One major dissimilarity, however, is that "Claire" is waterproof while Olay is just water-resistant. klutzes beware.
There's no denying Clarisonic is an amazing product and worth the dough if you have it to spend. (See our video review.) But for its ability to deep cleanse, exfoliate, and give a great massage in the process, Olay's Advanced Cleansing system has surprised me with its great value.
