This week on The goop Podcast, Gwyneth Paltrow sits down with Gregg Renfrew, founder and former CEO of cult-favorite clean beauty brand Beautycounter. Renfrew shares her story of building—and selling—a billion-dollar business, being unexpectedly sidelined, and ultimately pulled back in when things began to unravel. She opens up about letting go of ego, redefining success, and beginning again with clarity and purpose.

“Being a twin feels like a superpower,” says Marlien Rentmeester, the 51-year-old founder of the obsessed-over fashion blog Le Catch, who shares more than a beautiful olive-toned complexion and incredible style with her identical twin sister, Coliena, a photographer. Both are mothers, and they also share/steal each other’s skin care and makeup—goop, Beautycounter, and RMS are mutual favorites.
