Gillian Anderson only recently developed her own skincare routine. The 56-year-old actress teamed up with L'Oreal Paris earlier this year as a global spokeswoman and is set to make her runway debut with the brand at the annual Le Defile fashion show for Paris Fashion Week. She told PEOPLE magazine: “I spent most of my life not really paying that much attention to any kind of a routine. She added: “What's great about the brand is that they're not asking me to pretend. And when it did, and I was at my first photo shoot, I think I was slightly stunned because it just felt so surreal.
