Scrub the dead skin off your face and enjoy some exfoliation! It sounds gross but feels really good. Exfoliation is the process of buffing off the outer layer of skin cells or shedding parts of a surface.
Exfoliation often refers to something people have done at a spa, but it’s not just for humans. A tree's exfoliation involves its bark being peeled off or leaves falling off. You could also call a snake shedding its entire scaly skin exfoliation (though it's officially known as ecdysis or shedding). When a plant loses its leaves, it's exfoliation — this is appropriate since exfoliation stems from the Latin exfoliare, "to strip of leaves."
