This is good information to know. Depending on one's natural skin tone, plus location, time in the sun, and clothing worn, etc 5-6 SPF may be enough for some people. If we are outside for short times, or mostly in shade, and have hats, long sleeves, etc, we often don't wear sunscreen. I have some great shea butter that I'm using as moisturizer right now that I will try out as a light sunscreen this summer.
