Hand sanitizer is a chemical that is valuable to humans; its purpose is
to kill the pathogens on your hands. It is recommended that, instead of
using it excessively, hand sanitizer only be used when you have just
touched an unclean surface or before you use your hands to eat/touch
your face/contact your fluid membranes. Why do you think that is?

because its a chemical .

Explanation:

Our human body is made up or organic compounds and it is much used to natural things . Now you would ask - why you cant make a natural hand sanitizer and make it compete with a chemical hand sanitizer . well ! Modern problems need mordern solution . we humans are just too young to this world , to this universe but we have badly polluted our envirnment by releasing too much chemicals in our atmosphere in just so small amount of time . everytime you touch any object it may contain harmful viruses , bacteria , germs , dirt . where our natural sanitizers cant guarantee you with 100 % protection . whereas our chemical santizers do till a pretty much good extent . But chemicals may be harmfull to our skin (no doubt) so its said not to be used in exesive manner .

the answer is c most of the fortnite players usually buy v bucks to get the battle pass and other cosmetics but some players who are referred to as "no skins" don't   buy skins and are usually noobs.
