Given that I’m a whitey (and OH SO WHITE) and it’s summer here in the southern hemisphere, I bought myself a thingy of tanning creme…that has a SPF of 15.
Now I only apply it every few days (just enough to take the white out, a real tan would look ridiculous on me) but curious how long the SPF thing is meant to last.
With most sunscreens, they need re-application around every four hours to provide protection. Nobody is going to put this stuff on every four hours, unless they want to look like Serena Williams at the end of the day…
So does the SPF last as long as the tan? IOW, can I expect a protection factor of 15 for a few days, or does it last the usual few hours?
