Most people don’t think about wrinkles until they’re already staring at the first crease in the mirror, which is a mistake (and we’ve brought the receipts!) In a recent survey of U.S. skin care shoppers, only 7% of Gen Z worry about fine lines. That concern jumps to 22% for Millennials, and climbs even higher for Gen X at 43%. As for the Baby Boomers, nearly half (45%) of them list fine lines and wrinkles as a top concern.
