Let's concentrate.
"The general thinking of people who wear perfume is that fragrances with the highest percentage levels of essential oils in the final mix are superior because they are richer, project more and are longer lasting. This is a misconception, as a scent's true lasting power and character is more a function of the perfumer's selection of individual ingredients used in the initial formula recipe rather than simply increasing overall oil levels. An 8% mix in one scent can outperform a 16% concentration in another."
