Eau Fraiche

Eau fraiche contains the lowest concentration of fragrant oils, typically in the range of about 1 to 3 percent. Many aftershaves fall into this category. Once applied, the scent wears off in about an hour.

When you spray or dab on a fragrance, you first smell its top notes, the scents that diminish quickly, typically within minutes. Because eau fraiches wear off quickly, your body chemistry doesn’t have much time to interact with the oils in a way that notably alters the scent, for good or bad, the way that they do with more intense fragrances.
