Luckily, our own Ally Noel's daughter is a teen skincare expert, and she was happy to tell us what's what.

Read on for Charley's teen skincare picks, which include an old favorite, a celeb-created line, and a line that parents will happily pilfer from their kids. Plus, find out which pimple patches actually work—and which look the cutest.

We've got more teen insight, too, including 70 Life Skills Your Kid Needs Before College and great Pre-College Summer Programs for High School Students. Because no matter how much we dread it, our little ones grow up!
