how-does-sunscreen-work

Key Takeaways

  • Sunscreen works by stepping in between your skin and the sun, either by bouncing UV rays away or soaking them up before they can cause trouble. 
  • Mineral formulas stay on top of your skin like a lightweight shield, while non-mineral formulas pull UV rays in and break them down so they don’t harm your skin. 
  • SPF tells you how long you can stay in the sun before your skin starts to redden, which is why reapplying and choosing broad spectrum protection makes such a difference. 
  • Both mineral and non-mineral sunscreens help keep your skin protected, so the best choice is the one that feels good, fits your day, and makes you want to wear it every time you head outside.
