Yom Kippur: We learn a Kallah and a king can wash there face on yom kippur(tosfas yeshanim yoma78) but we pasken chatzei shiur assur so how can this be permitted?
A:Rav Chaim Kaniefsky says that maybe the tosfoas yeshanim hold chatzei shuir is only by achila.
A:Rav Michal Yehuda Lefkowitz says the maseh rechitza is the whole body and there is no shuir for it,rather washing ones face is is not like rechitza.(M’rafsin Igri)
