All I can think while reading these comments is "no wonder women are always telling men to properly clean their asses, because they keep running into these 'my hand is fine enough' dudes"
A loofah is for the body, you could use a washcloth for the face but I don't do that my facial skin is too sensitive. Also you don't need to use a loofah if you're skin is too sensitive, you can just use a nice sponge but honestly even your hands are fine if that works for you. I was honestly just joking a bit haha
