If I'm going out in the shade/sun for an hour, is it better to not wear any protection? Related, is the sun in small amounts / small intensities good for the skin?
In other words, is a little exposure a good thing that can quickly become a bad thing or should I minimize any and all exposure.
A directly related question, should I ever wear spf 15 or should I just put the max spf on everywhere I go?
edit: My current thoughts (very unscientific) are that wearing SPF 15 for most places provides a good balance between burning too fast and getting natural exposure to the sun.
Maybe the healthiest solution is to use the rub in tanner once per week and use SPF 70 for outings?
