Cameron Diaz

Dying to know the secret to Cameron Diaz’s radiant “I’m on holiday” complexion? According to makeup artist Benjamin Puckey, who helped get the actress looking glam for our St. Barts cover shoot, it comes pretty naturally for her. “After arriving, I bumped into Cameron at the gym and was blown away by the quality of her flawless skin,” he says. “It’s definitely proof that her healthy lifestyle works!”

To help further perfect and protect her against the tropical sun, Puckey used one of the star’s faves, Colorescience Sunforgettable Mineral Sunscreen ($62; colorescience.com), and topped it off with Nars Bronzing Powder in Laguna ($38; narscosmetics.com). As he created the minimal look, Diaz impressed with her vast knowledge of skincare and makeup approaches for different kinds of photography and film lighting. “She knows a lot about it after spending long days on set,” he notes. An added touch that gave her body a beautiful sheen was walnut lotion by Mario Badescu ($10; mariobadescu.com). “Cameron was very happy with the outcome!”
