The Acne Whisperer's Secret Weapon? Raiding Her Kids' Skincare Stash

Sofie Pavitt, the skincare expert known as the "acne whisperer," lets a favorite trick slip in the video series "Face It": one of her go-to products is actually borrowed from her own children's routine. The founder also settles the debate on how often we really need to be washing our faces, speaking with the confidence of someone whose business is reading skin for a living. She's candid, too, about beauty industry trends she considers more hype than help - a reminder that expertise, not marketing, is what she's selling.
