spf-30-vs-spf-70

Key Takeaways

  • SPF 30 blocks about 97% of UVB rays, while SPF 70 blocks closer to 98.5%.
  • The percentage gap is small, but SPF 70 gives you a bigger buffer when you’re outside for hours or when UV is at full strength.
  • SPF 30 is the everyday workhorse and what most dermatologists call the daily minimum.
  • SPF 70 earns its spot for fair or sun-sensitive skin, tropical vacations, winter activities like skiing and snowboarding, and marathon surf days.
  • Either way, broad spectrum coverage and reapplying every two hours (or after swimming) is what actually keeps your skin protected.
  • Is SPF 30 or 70 Better?SPF 70 is better for long days in strong sun or for fair, sensitive skin. SPF 30 is better for everyday use and is the minimum most dermatologists recommend. In short: SPF 70 = more protection. SPF 30 = enough for most days.
