Could be related to hygiene? I've heard those things can easily store bacteria in them, and I can see dead skin cells just getting stuck and not really cleaning out properly. If one's hands are wet and wrinkly enough, that's usually enough for scrubbing.
It might also be bc he's bruised all over and thus hands are a bit more gentle than the whole scrubber itself.

Nobody mentioning, but what the actual... Why does Hanrim use the loofah like that. No scrubbing just as a foamer and then cleaning with hands? Is it because he wants to touch him directly or??
