Wow... this stuff actually works!
I've now had a chance to try this stuff out over several rounds of golf, several walks, and several hikes.
(And for context, I live at 7500 ft. above sea level where the sun's effects tend to be more pronounced.)
BOTTOM LINE: This stuff actually works. It's comparable to the "sun stick" product Primal Life sells except with two key differences:
1) You can use much less of it at a time. (For instance, I'll spray 3 drops on an arm and rub it in, and those 3 drops easily lasts me 90 minutes on that arm.)
2) It smells a little better than the "stick" version, in my opinion.
3) It's easier to rub into the skin than the "stick" version.
That said, I think the stick version lasts slightly longer and is more "obvious" (due to the white color) where it's been applied.
But if you're like me and have a background in using essential oils, this product will feel very "at home" in that regard. It feels and acts (and smells) very much like a targeted essential oil blend.
All I know is it works. I haven't been burned once since using it.
