LOS ANGELES, Calif. -- The holiday season is just around the corner, and that means we'll all be traveling more... eating more... and celebrating more, which can take a real toll on our skin. Skin Expert Jan Marini, who has worked with Paris Hilton, Naomi Campbell and Cher, gives her tips for taking care of your skin during the holidays.

LOS ANGELES, Calif. -- To celebrate the 15h Anniversary of his (highly covetable!) makeup line NARS, Francois Nars created a special limited-edition book to mark the occasion. It's called "15x15", and features 15 celeb portraits, including Naomi Campbell, Marc Jacobs and Isabella Rossellini, all photographed by Francois himself.

He also did all the makeup, of course, and shared with Glam Slam his tips for a classic and timeless look.

The British supermodel donned couture clothes and posed atop a building in Moscow, as the designer shot her for the latest issue of V Magazine.
