To remove the outer layer or polish away; to exfoliate or strip away.
From Latin ex- (out) + polire (to polish). This rare variant or near-synonym of exfoliate means to remove surface layers through polishing or scrubbing.
This word is nearly lost to time, replaced by 'exfoliate' in modern English. But 'expoliate' preserves the root 'polire' (polish)—literally 'to polish away' impurities, which is exactly what modern skin care does.
