When you discover a perfume, you sometimes get the impression that it changes over the course of a few minutes. A fresh and light fragrance at first may become more floral, softer, or woodier a few hours later.

This phenomenon is explained by the construction of the perfume in different olfactory notes: top notes, heart notes, and base notes.

Understanding this structure allows you not only to choose  a perfume more effectively, but also to better understand how to create your own conposition.

At Make Your Scents, it is precisely this discovery of the olfactory world that makes perfume creation so playful and exciting.

What is an olfactory note?

An olfactory note corresponds to a facet of the composition of a perfume.

Some fragrances are very volatile and disappear quickly, while others remain present on the skin for several hours.

Perfumers traditionally organize compositions according to three major families of notes:

• top notes;
• heart notes;
• base notes.

We often talk about an olfactory pyramid to represent this construction.

Each level plays a different role in the evolution of the perfume.

Top notes: the first impression of the perfume

Top notes are the first smells we perceive when we spray a perfume.

They are generally fresh, light, and very volatile.

They immediately set the tone of the composition, but they fade quite quickly to reveal the following notes.

Among the most common top notes, we find citrus and certain fresh notes.

For example:

• bergamot;
• neroli;
• certain green notes;

Bergamot often brings a sparkling, luminous, and slightly tart sensation.

Neroli can offer a fresh and elegant floral scent.

Top notes are therefore essential: they create the first impression of the perfume.

Heart notes: the personality of the perfume

Once the top notes have faded, the heart notes gradually appear.

They often make up the most identifiable part of the composition and give it its main character.

Heart notes are generally more present and longer-lasting than top notes.

We frequently find floral, fruity, or spicy notes in them.

For example:

• jasmine;
• rose;
• lotus;
• lily of the valley;
• ylang-ylang;
• violet;
• tuberose;
• honeysuckle;
• cardamom.

A floral composition could, for example, combine jasmine and rose, while a more intense perfume could play with notes like ylang-ylang or tuberose.

Heart notes represent, in a way, the identity of the perfume.

Base notes: the signature that remains on the skin

Base notes appear more slowly.

They are generally deeper, warmer, and less volatile.

They are what give the perfume its longevity and depth.

They can remain present for several hours after applying the perfume.

Among the base notes often used in perfumery, we find:

• vanilla;
• amber;
• sandalwood;
• vetiver;
• patchouli;
• cedar;
• musk;
• leather;
• benzoin.

Vanilla, for example, brings a soft and enveloping facet, while sandalwood brings a woody and creamy dimension.

Patchouli or leather can give more depth and character to a composition.

Base notes thus constitute the true signature of the perfume.

How does a perfume evolve on the skin?

When you spray a perfume, all the notes are present in the composition.

However, they do not reveal themselves at exactly the same time.

In the first few minutes, you mainly perceive the top notes.

Then, gradually, the heart notes take up more space.

Finally, after several hours, the base notes become the most present.

This is why a perfume can seem very different between the moment you spray it and several hours later.

It is therefore always interesting to let a perfume evolve before deciding if you really like it.

Is the olfactory pyramid always that simple?

The distinction between top, heart, and base notes is a simple way to understand the construction of a perfume.

In reality, the boundaries are much more subtle.

Certain materials can appear at several stages of the perfume's evolution, and the different notes are constantly mixing with each other.

Perfumery relies precisely on this balance.

A fragrance can enhance another, bring contrast, or soften a more intense note.

It is this combination that gives birth to a harmonious composition.

How to use top, heart, and base notes to create your perfume?

When creating your own perfume, understanding the olfactory pyramid can help build a balanced composition.

You can start by imagining the general atmosphere you want to give your creation.

Do you want a fresh and luminous perfume?

You can favor a note like bergamot or neroli.

Are you looking for a floral composition instead?

Jasmine, rose, lotus, or violet can become the heart of your perfume.

Finally, do you want to bring more depth and longevity?

Vanilla, sandalwood, patchouli, cedar, or amber can complete your composition.

The idea is not necessarily to follow a strict formula, but rather to understand the role that each fragrance can play in your creation.

Creating your perfume with Make Your Scents

With Make Your Scents kits, perfumery becomes a creative experience accessible to everyone.

Each kit allows you to discover several fragrances, smell them individually, and then test different combinations to create a personal composition.

You can thus experiment with different combinations of fresh, floral, woody, gourmand, or enveloping notes.

The goal is not to reproduce an existing perfume, but to let your preferences and creativity speak.

Over the course of your trials, you learn to recognize the fragrances you like and understand how they evolve when combined.

A perfume tells a story in several stages

Top notes give the first impression.

Heart notes reveal the personality of the composition.

Base notes bring it depth, longevity, and character.

Understanding these three levels allows you to better appreciate a perfume, but also to better understand all the work hidden behind an olfactory composition.

And when you create your own perfume, this discovery becomes even more interesting.

Because a perfume is not just a simple smell.

It is a composition that evolves, transforms, and reveals itself gradually.

And with Make Your Scents, it is up to you to imagine yours.
