I am actually confused when it comes to sunscreen. I prefer the spray on kind. I know SPF stands for the protection rate but not how high an SPF I need on the bottle. I also don't know how to figure out how often to apply it before I scorch inadvertently.
My situation is that of having to be in direct sunlight and heat for over 2 hrs over course of three days often seated. What's the best SPF and duration before reapplying for me? Thanks.
Now here is a link to a blog that demystifies all about SPF's and how to figure out how much an SPF screens UV rays and how to translate an SPF number into how long it lasts before needing a reapplication.
