means A cosmetic treatment that uses tiny abrasive crystals or a diamond-tipped wand to buff away the outer layer of dead skin cells, meant to smooth texture and reveal fresher skin underneath.

from Built from Greek pieces: 'micro' (small) plus 'dermabrasion' itself a compound of 'derma' (skin) and 'abrasion' (from Latin 'abradere', to scrape off). Dermabrasion as a harsher surgical skin-resurfacing technique predates it; 'microdermabrasion' emerged later as the gentler, cosmetic-counter version — same scraping idea, shrunk down and softened for a spa menu rather than an operating table.
