Retro screen siren or sultry starlet? At Sephoras Santa Monica Place store this past Friday, a team of Koh Gen Do makeup artists was doing its best to get the women of West LA red carpet-ready. Not surprisingly, each artist agreed that skincares at the root of any polished beauty look. So whether you asked for a liquid cat-eye or a matte red pout, each artist started with Koh Gen Dos Moisture Spa Gel ($62), a moisturizer that doubles as a primer and, apparently, reigns supreme among the men of Mad Men. Denika Bedrossian, the talented makeup artist responsible for Miley Cyrus, Kelly Osbourne, and"as if to prove her range"Adam Levine, was on hand to dish insider tricks. Her number one tip? Prep the lips by exfoliating, moisturizing, and applying just a bit of concealer before applying any sort of colour. If youre using a matte lipstick, set with translucent powder for extra staying power. As for the rest of your look, at this time of year, Just have fun!
