For the past 10 years, Dr. Shereene Idriss has been a practicing dermatologist in New York City. And in 2018, she also became a social media star. Today, Dr. Idriss has 657,000 followers on Instagram, 441,000 on TikTok and 704,000 on YouTube. In October 2021, she opened her own practice, Idriss Dermatology, in Manhattan. Then, a year later, in October 2022, she launched PillowtalkDerm, her skin-care brand, named for the content series she'd become known for. In #PillowtalkDerm social media content, Dr. Idriss can often be found in bed, in her pajamas, educating her followers about skin care in her typical no-B.S. style. While Dr. Idriss built her robust following of "nerds," as she calls her followers, by calling out trends she's deemed unworthy of their hype and mostly shying away from paid brand deals, it's worth noting that she's also very funny. When PillowtalkDerm, the brand, became available for pre-sale in September 2022, it sold out in less than 36 hours. It launched with three products, all aimed at hyperpigmentation and discoloration and labeled the Major Fade collection. Since then, it has released just one more product, the Depuffer, in April 2023. The arnica-filled roller serum was inspired by Dr. Idriss's patients recovering from treatments including injectables and Sculptra. Dr. Shereene Idriss, spoke with Glossy senior reporter Sara Spruch-Feiner about the inception of #PillowtalkDerm on social, the reason she's turned down lucrative brand deals and the decision to kick off the brand with a focus on hyperpigmentation.
