All 1981 fragrances use the unique ingredient Iso E Super. This allows the wearer to have a personal, bespoke reaction, as this blend manifests a different aroma on every individual as it interacts with the individual’s chemicals, rather like your own laboratory on the skin, where you, the wearer get to create your own blends within the 1981 collection, knowing that each one is personalised to you, either worn on its own, or mixed with another within the collection, giving you the option to create your own new fragrance within the collection
