Sitting at a table in Freds restaurant at Barneys in Beverly Hills, Linda Rodin, creator of the cult beauty product Olio Lusso Face Oil, is striking: shiny gray hair pulled back in a chic updo; signature oversized glasses that give off a '70s rock star vibe; bright, I-am-in-the-room lipstick; artsy rings stacked on her fingers. She is chic, modern and, at 67 years old, the epitome of the current cultural moment — as seen in recent fashion campaigns, TV shows and films — showcasing women 60-plus as vital, beautiful and in the thick of living rather than winding down.
