Sunscreen Facts You Don’t Know

sunscreenfactsIf you think that choosing the right sunscreen is as easy as starting of with a higher SPF on your annual summer sun holiday and decreasing it to a lower one by the last few days with a bit of redness in between, you’re definitely old school in your way of thinking. But don’t worry…you’re not alone. The majority of people in the UK don’t know the first thing about sunscreen basics. Let us help you out:


  • A sunscreen of SPF 15 (or higher) should be worn every day.


  • Sunscreen should be applied approximately every two hours to remain effective.


  • You’ll need a broad-spectrum sunscreen to be protected from both UVA (ageing/cancer causing) and UVB (burning) rays.


  • The SPF only protects you from UVB rays. Your sunscreen will need to contain ingredients such as zinc or titanium to protect you from UVA.


  • SPF 15 protects you from 93% of UV rays. SPF 30 protects you from 97% of UV rays. SPF 50+ protects you from 98% of UV rays.


  • Even on a cloudy day, up to 40% of UV rays make it to the earth.


  • UV rays can still reach you in the shade.


So these are a few of the basics. Probably the hardest thing to understand is the SPF rating. Here’s the way to calculate it: If you can stay in the sun for 10 minutes before burning, SPF 15 will protect you for 15 x this length of time. So, 10 x 15 = 150 minutes’ protection. As the length of time in which people burn is individual to the person, the SPF rating is unique to each individual. You’ll be safest if you reapply sunscreen every two hours and again after swimming or exercise.
