While Charlize Theron made a statement with her sparkly 31-carat Harry Winston necklace and black Dior Haute couture gown, it was her radiant skin that most caught our eye at the 2014 Oscars.

Now, we have the secret to the Oscar winner's impeccable complexion: Sean Penn's South African love, 38, visited celeb facialist Joanna Vargas for her trademark Triple Crown Facial on Sunday morning.

The three-step treatment, beloved by stars like Zac Posen and Mandy Moore, aims to drain puffiness and tighten the skin for a more defined jawline and cheekbones.

Vargas begins with a diamond peel to gently exfoliate and remove impurities and then stimulates the skin with microcurrent technology that purports to promote collagen and elastin. Lastly, Vargas applies a vitamin-rich oxygen treatment to boost radiance. The hour-long facial costs $400 with Vargas or $250 with a senior esthetician.
