Using Sunblock If you are among those likely to burn, use a sunblock with a PF of 15 or greater. You can use a lower number if you are less likely to burn. An ounce of sunblock will effectively cover your entire body. Apply sunblock at least 15 to 30 minutes before venturing out into the sun and re-apply at least every hour. Re-apply more often if you are perspiring heavily or swimming. Use sunblocks with higher PFs on areas that need extra protection like the tip of your nose, your ears, your collarbone, the tops of your feet, and your shoulders. Do not use sunblock on your lips. Instead, use only sun protection products designed specifically for lips. Keep all sunblock and sun medications away from your eyes.
