If you were born between roughly 1996 and 2002, you likely grew up seeing Victoria Justice’s name splashed across the TV screen in your family room. Whether you knew her from Nickelodeon’s Zoey 101 (my senior editors and directors, please rise) or Victorious (my hand is raised high in the air right now), Justice was the hallmark of cool-girl style—from the bright blue streaks in Lola Martinez’s hair to Tori Vega’s trendy L.A. outfits and long, blown-out, bouncy curls. But when I meet Justice over a call, I find the star in a much more relaxed state: wrapped up in a robe and ready to divulge the latest in her personal beauty journey—a brand-new fragrance venture called Naked Perfume.

The brand, launched in collaboration with longtime beauty founder Randi Shinder, almost felt fated as the two bonded over a shared passion for beauty and an unlikely health issue that linked them together. “We connected immediately over the fact that we both have Hashimoto’s, which is an autoimmune disorder,” she tells Who What Wear. The disease, which happens when the immune system attacks healthy thyroid glands (according to Mayo Clinic), caused both women to approach beauty—especially the products they used on their skin (“It’s the largest organ on your body!” Justice says in exasperation later)—in a much different way.
