Below is a real world experiment with one of my favorite brands of sunscreen. BlueLizard sunscreen gives great protection and the bottle turns blue when there is sufficient UV light to cause skin damage.
The first photo was taken in the car while in the garage (and the bottle is white). The second photo was taken ten minutes later after driving just a few miles in the afternoon sun (in Seattle). The bottle was never outside – the only UV light came through the driver’s window. As you can see the bottle is bright blue! This means you are getting significant UV exposure through the car window. I have done this experiment inside my home and the same thing happens. UV light passes through windows, so protect yourself and always wear your sunscreen!
what do you think of sunless tanners? I’ve heard St. Tropez In Shower Gradual Tan is good. Do you if this is a good one or do you have others that you recommend? Thanks for any info on this!!
Hi Lynn,
I like sunless tanners- but I am not great at applying them well. St. Tropez is one of the top shelf brands- so you can’t go wrong. I love the gradual tanners because you can’t mess up and they tend to smell a little less. Another one for those on a budget is Jergens gradual tanner. A sunless tan is always better than a real one.
