Sunblock vs Sunscreen: Is There a Difference?
While these terms are often used interchangeably, there actually is a difference.
Sunblock is a physical blocker, preventing the sun's rays from reaching the skin. Sunscreen contains chemicals which absorb harmful UV rays.
Sunblock is often a better choice for sensitive skin, which can become irritated from sunscreen's chemicals. Read more about what to look for on the label when selecting a sunscreen or sunblock.
Use a Shot Glass worth of Lotion on Face and Body..
Even if you think you are applying your sunscreen liberally, you still may not be using enough.
Doctors recommend that you apply the equivalent of a shot glass of sunscreen to the exposed areas of your body and face, which is about two tablespoons. You should be using a nickel's worth on your face alone.
Sunscreens simply aren't waterproof and manufacturer's are no longer allowed to claim they are. They can however use the label "Water Resistant."
Check the label - if you are using a water resistant sunscreen, you may need to reapply as often as every 40 minutes.
There they are - right in the middle of your face - getting just as much sun as the rest of your skin. They need protection too!
