the only beauty treatment that costs nothing and actually works while you do nothing.
means Sleep regarded as essential to keeping one's looks fresh and healthy, especially the extra rest taken to appear well-rested and attractive.
from An English phrase from the early 19th century, built on the old folk belief that sleep itself restores and preserves good looks — that the body literally repairs its appearance through rest. The romance turned out to hold some truth: skin really does regenerate overnight, so the dark circles and dull complexion of a sleepless night are no illusion. The phrase first appears in print in the 1820s and has been reassuring the tired and vain ever since.
