A member of one of France's most iconic fashion families is the new face of Lancôme.

Julia Restoin Roitfeld -- the 30-year-old daughter of French Vogue editrix Carine Roitfeld -- has been tapped for the luxury beauty brand's Ultra Lavande Spring 2011 color collection ad campaign. Shot by Mario Testino in Paris, the svelte brunette models jolts of lilac on fingertips, lips and lashline in a très chic makeup line designed by creative director Aaron de Mey.

Slinking for a camera lens won't be new to the Parisian native, who has previously been the face of Tom Ford's Black Orchid fragrace. Ironically, Restoin-Roitfeld will be Lancôme's only current French spokesmodel, joining an increasingly star-studded roster that includes the likes of Julia Roberts, Kate Winslet and Penelope Cruz.

We hear the Parsons School of Design graduate is a serum fiend who counts the anti-aging Génifique among her favorite Lancôme products. With a mom who has an extensive history working in fashion -- for brands like Gucci and Yves Saint Laurent for years before making her way to the top post at French Vogue -- the two are regulars on the international catwalks of society events.

Mom's number one beauty tip to daughter? Don't overpluck your eyebrows.

From the full, high-sweeping arches seen in the spring ad, it looks like Restoin Roitfeld recognizes that mother knows best.

Lusher, more natural brows are an overall beauty trend of the moment. Check out how two new products are encouraging women to toss aside the tweezers and grow their own pair out.
