Recently, I had the privilege of attending a makeup master class hosted by Colgate Optic White with Celebrity Makeup Artist, Mario Dedivanovic. Mario's most notable clientele includes Kim Kardashian, Jennifer Lopez, Katy Perry, Priyanka Chopra, Chrissy Teigan and Christina Aguilera to name a few.  Mario disclosed a few of his favorite makeup tips and demoed looks to mirror some of this year's Oscar faves. Inspired by the master class, here are some new beauty tips and tricks.
