The marketing word for aging backwards, except nobody actually has

means The process of making something look, feel, or function young and fresh again — restoring youthful vigor to a person, place, or thing.

from Built in the 1700s from Latin re- ('again') plus juvenis ('young' — the same root that gives us 'juvenile' and 'junior'), so rejuvenation literally means 'young again.' It first described a hoped-for medical or biological reversal of aging before marketers got hold of it and applied it to everything from skin cream to shopping malls.
