Track Your Vitamin D, Fade to Invisible
Smart UV-sensing patches that visually track vitamin D synthesis in real-time
Get exactly the right amount of sun for optimal vitamin D levels. Our translucent patches glow soft blue as your skin produces vitamin D, then gradually fade away—like a ghost disappearing—precisely when you've reached your personalized sweet spot.
✨ The Wow Moment
Apply a translucent patch before heading outside. Watch it glow as your skin naturally produces vitamin D, then fade to invisible exactly when you need sunscreen—all tracked via your phone.
