Facet

A facet is one recognizable side of a note or material — a single direction it leans in, not the whole of it. Patchouli is one note, but reviewers talk about its earthy facet, its chocolatey facet, its camphoraceous facet, because the same oil shows different faces depending on the material's quality and what it sits next to. Rose runs jammy, green, spicy, or honeyed. When you read that a fragrance has a powdery facet or a smoky facet, the writer means one detectable aspect of how it smells, not a separate listed ingredient.

The word is borrowed from gem-cutting, where a facet is one cut face of a stone, and the metaphor is exact: turn a note in the light and a different side catches. That is why "chocolatey" can describe patchouli without chocolate being anywhere in the formula — it names a face of the note, not a thing added to it. It is also why two patchouli fragrances can smell nothing alike. The note is the same; the facets each composition pulls forward are not.

One source of confusion: perfumers and Grasse-trained houses also use "facet" in a second, broader sense — for whole olfactory families a composition can be dressed with, like the hesperidic facet, the green facet, or the mossy facet. In that trade usage a facet is closer to an accord-family than to a single note's sub-character. Most enthusiast and review writing means the first sense; brand copy and perfumery courses often mean the second. The page below uses facet in the everyday reviewer sense and flags the trade meaning where it matters.
