I am only the mailing list of the mayo clinic , and came across this item on sun exposure.
please see http://www.mayoclini...en/art-20045110
- the important thing is to also cover your body with clothes
- sunburn can happen at any time, even when it is overcast
- the difference in SPF don't mean that much, if the product your are using has a higher rating it does not mean that you stop reapplying it
- the most important thing is to apply the product generously use it , keep on using it and per the label
the article has some interesting information about sunscreens and is well worthwhile reading
