Stick-type sunscreen is a convenient way to put a layer of grease on
exposed skin in cold weather, and it can be carried in your pocket for
touch-ups.

What is "frostburn"? Do you mean windburn or frostbite? The former is a form
of sunburn, in which case sunscreen is indicated; the latter is a cold
weather injury, and sunscreen will not help.
