Julia Roberts' love of soft, natural makeup ruled the red carpet premiere of 'Eat Pray Love', as it does throughout the exotic changing backdrops of the film, her makeup artists tell us.

At the premiere in New York, The "Pretty Woman" paired her sleek black Stella McCartney blazer, mini Diane von Furstenberg shorts and strappy black Roger Vivier heels with equally chic and modern makeup.

Makeup artist Genevieve Herr used Lancôme's Teint Miracle Foundation (launching in September), Laura Mercier's Secret Concealer and Brightening Powder plus a plum cream blush on the apple of the cheeks to set skin.

Then Lancôme's French Touch Color Design Quad from the new fall French Coquettes collection was blended for a smoky plum eye, and topped with Le Crayon Khôl in Black Ebony and Définicils Precious Cells Mascara for a glamorous finish.

Lips stayed a feminine pink -- Roberts' clutch shade for red carpets -- with Le Lipstique Lip Liner in Sheer Natural, creamy Color Design Lipstick in Love It! and a smidge of Juicy Tubes in Spring Fling -- also an Angelina Jolie favorite-- and all by Lancôme, for whom Roberts is a new brand ambassadress.

Yet in the film, makeup takes on a less glitzy and more natural tone as Roberts channels memoir author Elizabeth Gilbert during a post-divorce journey that treks through Italy, India and Bali in a wandering search for spiritual enlightenment.

And like any true traveler who must navigate the persnickety world of TSA carry-on regulations, makeup artist Richard Dean (Julia's onset favorite artist) says that he worked with one cosmetics bag for the entire film.

"We basically picked a set of products for this look and decided that as Liz traveled and tried to find herself anew, she would use the same products in her makeup bag, but in different ways that reflected the energy of her changing circumstance and emotional growth."

In Italy, where Liz finds new excitement in the simple pleasures of life, the makeup follows suit. "The blush moves from the outer cheekbone toward the apple of the cheek, more like a natural, warm flush. The soft rose lipstick is replaced with a more fleshy, nude color, more childlike," says Dean.

At the sweltering ashram in India where Liz takes on the challenging work of self-purification, her complexion mimics the golden tones of a hot sunset. Makeup is barely noticable, save for an Indian wedding scene where her eye pencils are applied in the traditionally decadent kohl style that symbolizes Indian femininity.

And in tropical Bali, a subtly smudged liner marks the eyes, while bronzer replaces blush for a sun-touched look. "Her lips are moistened rather than lipsticked. A naturally sensual woman has emerged," Dean divulges.

One of the greatest challenges in making the movie was not the travel or even the long hours filming, but rather keeping the makeup in place while shooting in humid New York in July, oven-like Rome in August, and India in September -- where temperatures soared into 100's daily.

"Le Stylo Waterproof eye pencil in Café was indispensable and the Aquatique eye shadow base saved the day. Eau Fraîche Douceur Micellar Cleansing Water is amazing in a hot climate for cleansing," says Dean.

In addition to those items, the other staples in Liz's makeup bag that make it through the changing scenes of the film include Juicy Tube in Simmer, Star Bronzer in Lumière and Color Design Cream Blush in Petticoat Pink -- which you'll have to hunt for on eBay, as the classic pink shade has since been discontinued. (Why, oh why, Lancôme?)
Aside from the delicious makeup, we hear from the Lancôme blog that the sumptuous food scenes in Italy will have you craving bubbling cheeses and saucily dressed al dente pasta.

Eat Pray Love opens in theaters on Friday. We're already strategizing our post-film pizza plans.

Lucky for us, LeRock's "Lift Up" jeans will help disguise our sins.
