Good Question

There is a scientific serial (monthly journal) called the Journal of Investigative Dermatology where learned Japanese argue endlessly over these points. They generally base their arguments on experiments in inbred mice using DNA probes. Their skills in written English cause me to turn to writing erotic corporal punishment fantasy to preserve my insanity. Every time I think I understand the reaction of skin to a noxious stimulus something comes along that convinces me I know less than I did twenty five years ago.

On the other hand, the point about anti-perspirants is always worth remembering. Tied into the human pilosebaceous system is the human apocrine sweat system. Our sweat glands are unlike almost anything else in the animal kingdom. Some forms of razor burn (male and female) are horribly exacerbated in hot weather and/or by excercise. Some of these forms respond to anti persperants in a way that I have never understood the rhyme or reason of. Women who sweat more tend to have more problems with folliculitities. Lastly, I swear that women have a broader range of folliculitities than men. So although we men pride ourselves on our razor burn we probably have no real reason to brag.
