The90 Gem Personal UV Exposure Sensor: Overview
The90 Gem is a jewelry-inspired UV sensor that tracks your actual sun exposure in real time. Protect your skin without guessing.
- Dual UV Tracking: The Gem measures both UVA rays, which cause premature aging, and UVB rays, which cause sunburn.
- Personalized Skin Profile: The companion app factors in your unique skin type, genetics, and habits. You get recommendations that fit you, not just general guidelines.
- Real-Time Reapplication Alerts: The app shows your estimated time to burn and tells you exactly when to reapply sunscreen, cover up, or step out of the sun.
- Everyday Wearability: Designed to blend into your existing jewelry stack, the Gem works indoors, outdoors, during workouts, and on casual days alike.
- Long-Term Habit Tracking: Daily exposure patterns are logged over time. See how your sun habits add up and adjust your routine accordingly.
Backed by a leading UV dermatologist, the The90 Gem is a practical tool for anyone serious about long-term skin health.
