Die-hard beauty fans, take note: Sephora has just launched a new beauty app for iPad users and it is teeming with content. The app serves as a mini social network, an online store, and an interactive catalogue, all in one. For instance, you can access the retailer’s BeautyTalk community, the Beauty & The Blog website, and YouTube channel. You can check out how-to videos and makeup application tips. And of course you can shop Sephora’s extensive collection of beauty products. The most interesting feature, however, is a side-by-side virtual mirror that allows users to follow along with a how-to video while simultaneously creating the look in the virtual mirror. (This feature is only available for iPad 2 users.) To check it out, head to Apple.com where you can download the app for free.
