Are you completely lost with Halloween makeup techniques? As a special accent to your costume this year, Sephora's Halloween makeover can help you look gorgeously ghoulish. The express service includes a professional application, and all you have to do is make an appointment at your local Sephora store and choose from six different looks below. A minimum purchase of $50 is required, but I'd say it's a steal, considering the makeup you'll get will last you well into 2011. And if you want to achieve a sweet Halloween makeup look, but prefer to DIY, Sephora's limited-edition Halloween Beauty in a Box is the perfect way to get stylishly spooky.
