You smell an incredible perfume on someone else, try the exact same fragrance on your own skin and… suddenly, it smells different. Sweeter, warmer, sharper or perhaps not quite as appealing. How is that possible?

A perfume is the same for everyone inside the bottle, but as soon as it touches the skin, an interaction begins between the fragrance composition, your skin and your surroundings. That is why the same perfume can smell different from one person to another.

Perfume comes to life on the skin

A perfume consists of different aromatic compounds that gradually develop after application. The more volatile fragrance notes are usually noticeable first, while other ingredients become more prominent over time.

This is why the first few minutes after spraying a perfume are not necessarily representative of how it will smell an hour later. The final stage of a fragrance, when the longer-lasting notes remain on the skin, is often referred to as the drydown.

And it is during this development that differences between wearers become particularly noticeable.

1. Your skin influences how perfume behaves

No two people's skin is exactly the same. Factors such as natural oils, moisture levels and the overall condition of the skin can influence how quickly certain fragrance compounds evaporate and how long a perfume remains noticeable. Dry skin often holds fragrance less effectively than skin with more natural oils. As a result, perfume may seem to disappear more quickly on dry skin.

This does not mean that your skin completely changes the perfume. The fragrance formula remains the same. It is mainly the evaporation and perception of individual fragrance compounds that can differ.

A Tip for Dry Skin
Does perfume tend to disappear quickly on your skin? Applying an unscented body lotion before your fragrance can help moisturise the skin. This may help the scent remain noticeable for longer. Check our other blog: How to make a Fragrance last longer.

2. What about your skin's pH level?

It is often said that perfume smells different on everyone because of the skin's pH level. It sounds logical, but the reality is more nuanced.

Human skin naturally has a slightly acidic environment. However, there is little reason to attribute every difference in the way a perfume smells solely to pH. Factors such as skin oils, hydration, temperature, evaporation and individual scent perception can all play an important role.

So the familiar explanation “it's because of your pH” is simply too limited.

3. Warm skin can change the way a perfume develops

Temperature has a significant effect on the evaporation of perfume. On warmer skin, volatile fragrance compounds evaporate more quickly. This is also one of the reasons perfume is often applied to warmer areas of the body, such as the neck and wrists.

But temperature does not only vary from person to person. Weather, physical activity, clothing and your surroundings can all make a difference. A perfume may therefore be experienced very differently on a warm summer day than in the middle of winter. A good example is perfume with frankincense. Frankincense is a resin and all resins need warmth to have the best fragrance development. 

4. Your natural body scent plays a part

Our skin has its own subtle scent. Sebum, perspiration and the microorganisms that naturally live on our skin all contribute to it. When perfume is applied, its fragrance composition interacts with this existing skin environment.

This may partly explain why certain aspects of a perfume seem stronger on one person than another. A sweet note, for example, might appear more prominent on one person's skin, while someone else notices mainly the woody or spicy side of the same composition.

5. Even Your Nose Is Different

Perhaps one of the most underestimated differences is not found on the skin at all, but in the way our brains process scent.

Scent perception is personal. Not everyone is equally sensitive to the same aromatic molecules. Fragrances are also closely connected to memories, associations and past experiences. A scent that feels warm and comforting to one person may evoke an entirely different memory or feeling in someone else.

There is another phenomenon at play as well. When you wear the same perfume for a prolonged period, your nose and brain can gradually become accustomed to it. Your brain starts paying less attention to a scent that is continuously present.

The result?

You may think your perfume has disappeared, while everyone around you can still smell it.

Spraying more perfume is therefore not necessarily the answer.

Other points you have to keep in mind:

· Perfume smells different on paper than on skin

A fragrance blotter is perfect for getting a first impression of a perfume. It allows you to compare several fragrances without covering your entire arm in different scents. But a paper test strip cannot fully predict how a perfume will develop on your skin.

· Your surroundings can change your fragrance experience

The same perfume can feel different depending on the circumstances. Heat speeds up evaporation. Cold weather can make a fragrance seem more restrained. Humidity, clothing and even the space you are in can also influence how strongly you experience a scent.

This may explain why a perfume that smelled incredible while you were on holiday suddenly seems different when you wear it back home. Not necessarily because the perfume itself has changed, but because both the circumstances and your perception of the fragrance have changed.

How do you know if a perfume truly suits you?

Give it time. Choosing a perfume based solely on the first spray is a little like judging a film after watching the first five minutes. The opening may be beautiful, but the heart and base notes determine much of how you will ultimately experience the fragrance.

Found a favourite on paper? The next step is to test it on your skin and give it some time. Don't just smell it immediately after spraying. Return to it after half an hour, a few hours and later in the day. This is when you discover which notes truly remain on your skin.

Instead of simply asking yourself “Do I like this?”, consider:

• Which fragrance notes remain after several hours?
• Does the perfume become warmer, fresher, sweeter or drier?
• How noticeable is the fragrance after a few hours?
• Do you still find it interesting three hours later?
• Does the fragrance feel like something that suits you?

So, Why Does Perfume Smell Different on Everyone?

Because our niche perfumes are not static. From the moment a fragrance touches your skin, several factors come into play: skin condition, natural oils, temperature, evaporation, body scent, surroundings and our individual perception of smell.

At LABO-NOIR, perfume is therefore about more than a beautiful bottle or a list of fragrance notes. It is about discovering what a fragrance does on your skin and finding the composition that truly stays with you.
