Does Vaseline really work?
I used it last year, and just want to know if I did it for no reason. Does it work?
I have never used it. Mechanism I suspect behind it working if it does is by limiting evaporative heat loss where as moisture (roughly equal to sweat) evaporates from skin of comb, the temperature drops causing its temperature to drop more than it would otherwise. The vaseline may seal in moisture and butter or some sort of fat may provide similar benefits.
I have yet to see where someone actually tested if vaseline works.
