What are Linear vs Non-Linear Fragrances?

Linear fragrance meaning. Some fragrances will smell the same to you or on you from the initial spray up until you wash it off; these are called linear fragrances. But then there are those that are more complex, and evolve with the layers within themselves over time. These fragrances are known as non-linear. 

Most quality fragrances will have the fragrance lifecycle as stated above. Oftentimes, low-cost fragrance manufacturers won’t invest in this complicated orchestration of scents; thus one of the easiest ways to identify a cheap perfume is that it smells the same the entire time it’s worn.

However, there are quality linear fragrances, as they do have their purposes. At work I may want to just have a citrusy/clean smell all day instead of a citrus that then turns into a musky leather after lunch. Contrast this to a date night where I might want a nice inoffensive fresh citrus that transitions into a smooth vanilla lavender as we end the evening. All about perfume.
