The useful answer
Eau de Toilette and Eau de Parfum describe fragrance formats associated with different concentrations. They are useful shopping labels, but they do not provide a complete account of how two fragrances differ. Start with the exact product name, then compare the notes the brand actually publishes. Our catalog does not infer an oil percentage or a number of hours from a label.
A line can contain different compositions
The Sauvage family is a practical example. Dior's collection page highlights citrus and pepper for the Eau de Toilette, while the Eau de Parfum introduces a vanilla emphasis. The Parfum puts mandarin, tonka bean and sandalwood in focus. Elixir turns attention towards spices, lavender and woods. These are distinct material descriptions, not four numerical settings on one scent.
This comparison is based on brand descriptions. It is not a side-by-side wear test, a ranking of artistic quality or evidence that the most concentrated option will be your favourite.
Choose the question before the bottle
If your interest is a particular note, compare note lists first. If you want to know how present a scent will feel, sample the exact variant in a setting that resembles your own routine. Write down what you notice immediately and what remains later, with the same application approach when possible. Your notes can become a personal reference rather than a universal performance score.
What about Elixir?
In this guide, Elixir is the name Dior gives to a specific Sauvage variant. We preserve that label without converting it into an invented percentage. Check each brand's own product description instead of treating every bottle called Elixir as an equivalent formula.
