Why Winter Sun Protection Matters: The Science Behind Your Skincare

Nov 15, 2024

Did you know that up to 80% of aging UV rays can sneak through those cozy winter clouds? ✨ Let's break down the science of winter sun exposure (spoiler alert: it's more important than you might think!)

The Three Types of Winter UV Exposure

Types of Winter UV Exposure Infographic

1. Direct UV Rays

Even on cloudy days, UVA rays (the ones responsible for premature aging) are working overtime

2. Snow Reflection

Snow can reflect up to 80-90% of UV radiation (compared to sand at 15% and water at 10%)

3. Altitude Impact

UV exposure increases by approximately 10-12% for every 3,280 feet in elevation

Pro Tip: UV damage doesn't take a winter break! UVA rays can penetrate through windows, meaning your skin needs protection even during those cozy WFH days or long commutes.
