Scent Detectives: The Three Layers of Perfume

Perfume is made from different scented ingredients. As time passes, some smells fade quickly while others last much longer. Perfume makers describe these layers as top notes, heart notes, and base notes.

• Top notes are the first smells you notice. They are often light, fresh, and quick to fade. Examples include lemon, orange, mint, and some herbs.
• Heart notes appear after the top notes begin to fade. They form the main smell of the perfume and may last for a few hours. Examples include rose, lavender, jasmine, and cinnamon.
• Base notes last the longest. They give the perfume depth and help hold the other smells together. Examples include vanilla, musk, amber, sandalwood, and chocolate.

Helpful memory trick:

• Top = first impression
• Heart = main character
• Base = lasting foundation
