The fragrance note is the foundation of any perfume, defining the character and aromatic identity of each composition. Knowing the fragrance notes helps you choose a fragrance that reflects your taste and continues to leave you feeling fresh and attractive throughout the day.


What are the aromatic notes?

Perfume notes are the components that make up a perfume's scent . They are classified into three main layers: top notes, which are the first you smell and are light and evaporate quickly; middle notes, which shape and characterize the perfume and appear after the top notes; and base notes, which are deeper, more stable, and long-lasting, giving the perfume its durability and depth. Each note plays a specific role in how the perfume interacts with the skin and evolves over time. Understanding these notes allows you to choose perfumes that best reflect your personality and suit your personal taste.


How do you understand a perfume's composition from the aromatic note? And what are its psychological and emotional effects?

To understand the composition of a perfume from the aromatic note, you must first understand how a perfume is divided into three basic levels, where each note plays a specific role in the perfume's journey on the skin and its effect on mood:

  • Top note: Appears immediately upon spraying the perfume and leaves the first impression. It is often light and refreshing, such as citrus or herbs, and gives a feeling of energy and freshness.
  • Middle note (heart note): Revealed after a few minutes, it defines the fragrance's main character. It typically contains flowers or mild spices and conveys a sense of warmth, romance, or confidence.
  • Base notes (fragrance base): Appear after several hours and give the fragrance its depth and durability. They include woods, amber, musk, or vanilla. Their psychological effect tends to be relaxing, familiar, and confers a sense of comfort and luxury.

Understanding fragrance notes helps you choose a fragrance that reflects your personality and evokes the desired emotions for every occasion, whether you're looking for everyday freshness or glamorous elegance for special occasions.



Sections of aromatic notes

Fragrance notes play a pivotal role in determining the character of a fragrance and how it evolves on the skin over time. They are usually divided into three main levels:

1- Top notes (opening):

They appear as soon as you spray a perfume and leave a lasting impression. They are often light and fresh, such as citrus, herbs, and fruits. These notes create a sense of energy and vitality, and immediately grab attention upon first contact with the fragrance. For example, perfumes that begin with top notes of mandarin and orange give the fragrance a bright, citrusy freshness that grabs attention from the first moment.

2- Middle notes (heart of the perfume):

It becomes apparent within a few minutes of spraying and defines the fragrance's core character. It includes flowers, soft spices, and rich fruits, adding balance and warmth to the scent and acting as a bridge between the top and base notes.


3- Base notes (perfume base):

They appear after several hours and linger on the skin for extended periods. They typically contain wood, amber, oud, and musk. These notes give the fragrance longevity and depth, and convey a sense of luxury and elegance, making them the key element in creating a lasting impression. For example, Double Sugar from Grass features a candy and vanilla base that creates a soft, creamy finish and a seductive sillage that lasts for hours, leaving an alluring effect on the skin.

How do aromatic notes interact?

The fragrance notes gradually interact with the skin, providing a complete sensory experience throughout the day. The process of note interaction is typically divided into three main levels:

  • The top note is the first scent you smell when you spray a perfume, and it creates the initial impression of the fragrance. It is often light and fresh, such as citrus, fresh herbs, or light florals. Top notes are strong at first but quickly fade, giving you a bright and energetic start.
  • After the top notes fade , the middle notes emerge to form the heart of the fragrance. These notes add depth and complexity to the scent and often include flowers, soft spices, or rich fruits. These notes define the fragrance's core character and remain more persistent than the top notes.
  • Base notes come last and linger on the skin for hours. They typically contain woods, oud, amber, or musk, giving the fragrance longevity and depth, leaving an unforgettable trail.

Understanding how these notes interact helps you choose a fragrance that suits your taste and occasion, and makes you aware of how a scent changes from start to finish, so you can enjoy a complete and personalized fragrance experience.

How do I choose the right perfume based on the fragrance note?

Choosing the right perfume depends largely on understanding the notes and how they interact with your skin and personal taste. Here's a practical guide:

  • If you like a fresh, energetic first impression, choose fragrances with citrus, fruit, or light herbal notes. These notes give you a feeling of freshness and are ideal for hot climates or everyday use.
  • To define the main character of a fragrance, focus on middle notes such as floral, spicy, or rich fruity notes. These notes reflect the fragrance's character and last longer than the top notes, making them suitable for social occasions and evening wear.
  • If you're looking for long-lasting wear and a lasting effect on the skin for hours, choose fragrances containing wood, oud, amber, or musk. These notes give the fragrance depth and elegance, making it suitable for colder climates and formal occasions.

  • Always test a perfume on your skin before purchasing it, because the interaction of the notes with your body chemistry determines how each note will appear over time, and the scent may vary slightly from person to person.
  • Try spraying the perfume on your wrist or behind your ear and wait 10 to 30 minutes to get a feel for the true heart and base notes of the fragrance before making a purchase decision.
  • Choose the perfume according to the season and occasion:
  • For summer fragrances, focus on fresh, light top notes.
  • For winter fragrances, choose rich, warm base notes to give a strong presence and long-lasting hold.
