The Real Housewives of Beverly Hills star Kathy Hilton, 62, might not know who hunky Dory is, but she sure knows a good skincare product when she sees one. In a recent RHOBH episode, Kathy hosted a spa day at her house for some of the ladies. Lisa Rinna, Erika Jayne, and Kyle Richards were treated to a facial and layer after layer of face masks that Kathy swears by, per E! News. The Knesko Nano Gold Repair Lip Mask helped all the ladies relax and soak in the glow. But for Kathy, they’re more of an every day essential (they’re also featured in that Instagram post!).
