'antiage' originates from Modern English, specifically the prefix 'anti-' (from Greek 'anti-') meaning 'against' and the noun 'age' (from Old French 'age' and Latin 'aetas') meaning 'age or life period'.

'antiage' developed as a compound from earlier forms such as 'anti-aging' and 'anti-age' used in the 20th century; marketing and product labeling led to the clipped form 'antiage' in recent decades.

Initially, the components meant 'against' and 'age' in their original languages; over time the compound came to mean 'intended to prevent or reduce the visible effects of aging' in modern usage.
