Eternity is a full green floral: freesia, sage and citrus up top, a big lily, carnation and rose heart, and a soft, powdery heliotrope, sandalwood and amber base. Eternity Air is a fresh fruity floral built on ozonic notes, grapefruit and black currant over peony and pear, drying down to musk, cedar and ambergris, so it wears lighter and cleaner.

Both are sold as Eau de Parfum, so concentration alone doesn't separate them; performance depends on the composition and your skin.
