I never realized how many YouTube beauty videos begin with the vlogger saying "Hi guys," but now I'll never be able to forget it. This video is almost as hypnotic as Michelle Phan's voice, people. Look for cameos from some of your favorite YouTube vloggers, and see if you spot an OnSugar blogger or two. I recognize a couple of people — hi, Nadine! — but if you can positively ID more, do so in the comments.
