  1. Hair has measurable sparkle points—you can increase the number in your hair with a shine spray. (Kind of obvious, yes, but who knew it was someone's job to count those?)


  3. Thanks to lasers, skin can now be analyzed all the way down past the basal layer—which means it's easier for scientists to see whether or not an ingredient we slather on is doing anything. (They used to take punch-holes of skin out of people's arms—ouch!)

And the biggest takeaway for me:

  1. If I'm diligent with the sunscreen, I won't look so bad at age 72! This creepy computer-generated "after" photo of me pinpoints where my wrinkles and age spots will appear and shows how strange my skin tone will become after a lifetime of UV-exposure. (Looks like I can cancel that plastic surgery appointment in 2052—my sagging jowls won't be so bad after all.)
