One of the most common comments in perfumery is: "This perfume doesn't last on me." In fact, most of our customers consult us about the longevity of a perfume when choosing it.
In most cases, claiming that a perfume doesn't last long enough has less to do with the fragrance's true longevity and more with how our brain and sense of smell process scents over time. This is where anosmia, also known as "olfactory fatigue," comes into play.
What is anosmia and olfactory fatigue?
Anosmia is the total or partial loss of the sense of smell. It can be temporary or permanent and can be caused by various factors, such as respiratory infections, allergies, or even genetic factors. However, what most influences the perception of a perfume's longevity is not total anosmia, but rather olfactory fatigue.
Olfactory fatigue is a natural phenomenon in which our brain stops perceiving a scent after a prolonged period of exposure. This happens because our olfactory system quickly adapts to constant odors to prioritize the detection of new stimuli. Thus, even if the perfume is still present on our skin and perceived by others, our own sense of smell becomes desensitized, giving us the impression that it has disappeared.
Why does it seem that a perfume doesn't last?
-
Olfactory adaptation: Our sense of smell is designed to notice changes in the environment as part of our survival instinct. Once we get used to a perfume, our brain filters it out and stops consciously registering it.
-
Different molecules, different durations: Not all ingredients in a perfume have the same longevity. Citrus and aquatic notes tend to evaporate quickly, while woods, resins, and musks can last for hours or even days on the skin.
-
Skin type and body chemistry: Each person's skin influences how a perfume adheres. Dry skin tends to retain fragrances less, while oily skin can prolong their duration.
-
Application method: Applying perfume to strategic points such as wrists, neck, and behind the ears can improve its longevity. It also helps to apply it to clothes, as fabrics tend to retain scents for longer.
How to avoid olfactory fatigue?
If you feel like you can't perceive your perfume after a while, try these tips:
-
Take olfactory breaks: Move your nose away from the fragrance and breathe fresh air before smelling it again.
-
Change perfumes occasionally: Alternating fragrances prevents your sense of smell from becoming too accustomed to a specific scent.
-
Ask other people: Often, the perfume is still perceptible to others, even if you no longer notice it.
-
Hydrate your skin: Well-hydrated skin helps to retain the aromatic oils of the perfume better.
The perception of a perfume's longevity is highly subjective and influenced by our own physiology and habits. Before discarding a fragrance due to supposed poor longevity, it is important to consider factors such as olfactory fatigue and the perfume's composition.
Ultimately, perfumes are designed to be enjoyed in layers and moments, and not always in a constant and uninterrupted way.
