## What is Sola?

Your skin is unique. Your sun exposure should be too.

Sola personalizes sun exposure recommendations based on your actual skin type. Sola is built for everyone.

HOW IT WORKS

1. Onboarding — You answer a few questions so that the app can learn you. In this way, it can recommend how much time you need in the sun and if you need to supplement.
2. Get your daily session — a personalized time recommendation based on your skin type, real-time UV index, and local weather.
3. Track and improve — monitor your vitamin D journey with daily scores, weekly trends, and monthly reports.

THE SCIENCE BEHIND SOLA

Sola's recommendations are grounded in dermatological research:
- Session times based on the Fitzpatrick scale and Minimal Erythemal Dose (MED) research
- Safe exposure limits — never exceeds 45 minutes, never recommends burning
- Seasonal awareness — adjusts for winter, summer, latitude, and hemisphere
- Cofactor guidance — always reminds you about K2 and magnesium
