In this video, the beautiful Michelle Phan does a side by side comparison -- literally, on her own face -- of two vibrating facial cleaners: the ubiquitous Clarisonic, which was the big holiday gift last year, and the Sun Face and Body Polisher, which we'd never heard of but, is apparently almost the same thing for way less money.

Michelle is game for making this a real test -- she smears mineral makeup all over her face, making a huge mess. And it's fascinating to see a real life demonstration of how the tools work, including a small mishap at the beginning. Always read the instructions!

We won't give away the ending, but if you're thinking about investing in one of these tools, it's definitely worth the five minutes to check out Michelle's side by side comparison.
