Does a Higher SPF Mean I’m Safer for Longer?

It doesn’t, and here’s why.

Higher SPF technically offers more protection, but it doesn’t provide a longer period of UV or blue light defense: reapplication and avoiding overexposure are still necessary. The same rules apply to melanated skin: even with a natural SPF of 13, you still need a fresh layer of sunscreen every two hours.

  • SPF measures how much UVB radiation your sunscreen blocks. Some research states that SPF 15 is good enough for daily defense, but most dermatologists (myself included) will push for SPF 30 rain or shine, indoors or out—especially for melanated skin.
  • Always look for broad-spectrum sun protection. This ensures that your sunscreen helps block both UVA and UVB rays (which all KINLÒ SPF products do, in addition to blue light).
  • Re-apply your sunscreen as directed. Your first layer should be applied 15 minutes before sun exposure, then re-apply your SPF every two hours (or right after sweating, swimming, etc.). If you’re afraid you’ll forget, our UV Detection Stickers will remind you when it’s time to break out the sunscreen again.
