First of all, happy Independence day, hope the sun is shining and those celebrating today are having an amazing time with friends and family. This past week England has been blessed with some incredible rays of sunshine! I’ve unfortunately been stuck inside working through most of it but i’ve got the day off today so will definitely be making the most of the 29 degree forecast! Safely though. I caught a snippet from a TV show a couple weeks ago about sun cream and was so shocked about all the things I didn’t know. In the past I have been fairly lax about sun protection because I don’t burn too easy and love that nice sun-kissed glow. However recently i’ve been a little more strict because no one wants to encounter premature ageing!
So I thought i’d share with you what I learnt from the show and a few things I already know about sun protection and what to look out for to help you out this summer…
- Sunscreen protects from UVA and UVB rays which can cause damage to the skin.
- UVA rays can cause lasting skin damage and premature skin ageing.
- UVB rays is what causes skin damage and sun burn.
- Both types of rays can lead to skin cancer.
- An SPF is the sunscreens ability to protect against UVB rays.
- According to skincancer.org the SPF number is how many times longer it would take for your skin to burn. For example if it takes you skin 10 minutes in the sun unprotected for you to burn, then wearing factor 30 would make your skin last 30 times longer which is about 5 hours.
- Protection from UVA rays is measured by a star rating of 0 – 5.
- The rating is measured in ratio to the SPF, so a low factor SPF with a 5 star rating means that the ratio of protection is the same. A high SPF with a 2 star rating means that the UVA protection is under half.
- Sun screen should not be expected to last any longer that 2 hours without re-applying.
- You should apply your first application of sunscreen for the day 30 minutes before entering the sun.
- 40% of the suns UV rays can reach the earth on cloudy days!
- Sun cream only has a shelf life of 2 years.
- You can improve sun protection by just sitting in the shade.
