Is skin lightening with lemon considered forbidden exfoliation?

What is forbidden regarding facial peeling is that which is done to change Allah's creation, not to remove melasma or dead cells. Using natural means like lemon, without peeling, is permissible as long as it does not cause harm. There is no detailed explanation from early scholars about the method of removal, but they had many natural remedies. One can refer to "Al-Mu'tamad fi Al-Adwiya Al-Mufradah" by Al-Turkumani.
