I, too, went with the Halo after someone here recommended it in some thread or other. But I have also overwhelmed it when out hiking like this last week. I perspire (polite for SWEAT!!!) profusely and it can overwhelm even the Halo. I stop remove, wring out, reapply and keep SWEATING.
After I get home I wet it down, add a drop of dish soap, massage and thoroughly rinse.
I do have the sun screen problem mentioned so I tend to apply below the eyes. If someone has a recommendation for a non-stinging version, I'd appreciate that. My dermatologist frowns at my forehead.
