Have you ever caught a scent in passing and found yourself somewhere else before you could even name it? A stranger walks by wearing your grandmother’s perfume. A candle in a shop smells like a holiday house. For a second, you’re back there.
For me, it’s J’adore. One breath of it and I’m a child again, looking at the gold bottle on my mum’s dressing table.
Scent does this faster than a photo or a song ever could. The reason comes down to how scent and memory are wired together in the brain.
Why smell works differently
Most of what you see, hear and touch passes through a part of the brain called the thalamus first. It acts like a relay station, sorting signals before sending them on. Think of it as a reception desk, where every signal checks in before it’s sent to the right place.
Smell takes a shortcut. Scent signals travel from your nose to the olfactory bulb, just above the nasal cavity. From there, they reach two areas deep in the brain almost directly: the amygdala, which handles emotion, and the hippocampus, which forms and stores memories. Put simply, smell skips reception and goes straight to the parts of your brain that feel and remember.
That’s why a scent can make you feel something before you’ve worked out what you’re smelling. The feeling arrives first, and the thinking catches up later.
Why scent memories feel so vivid
Researchers at Stockholm University have spent years studying memories triggered by smell, and their findings explain a lot.
In one study, older adults were given a word, a picture or a smell, and asked to share any memory it brought back. Memories triggered by words and pictures mostly came from their teens and early twenties. Memories triggered by smell mostly came from childhood, before the age of ten.
The scent memories also felt different. People felt more strongly transported back to the moment, and they had thought about those memories less often. Other research suggests smell-triggered memories are more emotional, too.
In other words, smell tends to unlock our oldest memories, and they come back with more feeling. It explains why so many of our strongest scent memories are from when we were small, like a mum’s perfume or a grandparent’s house.
A memory you never lived
Byredo’s founder, Ben Gorham, built one of his best-known fragrances around this idea. Bal d’Afrique, one of my favourites, began with his father’s diaries. His father spent years living and travelling in Africa, and Gorham read the journals as a way to connect with him. The fragrance is his imagined version of that journey.
It opens bright, with bergamot, marigold and buchu, a herb from South Africa. Then it softens into violet and cyclamen, over a warm base of vetiver and cedarwood.
This is the other side of scent and memory. A fragrance can bring back a moment you lived, and it can also help you imagine one you never did. Gorham never made that journey himself, but he could build a scent around what he pictured.
What this means when you choose a fragrance
Knowing how closely scent and memory are linked can change how you shop for fragrance, and how you wear it.
Pay attention to your first reaction. If you love or hate a scent instantly, it may be a memory talking. A fragrance that reminds you of someone you’d rather forget can put you off, however beautiful it is. The opposite is true too, which is why some scents feel like home the moment you smell them.
Wear something new for a new chapter. The scent you wear on a trip, or through a big moment in your life, will often become tied to it. Years later, it can bring that time straight back. A friend of mine wore YSL Libre on her wedding day, and now it will always take her back there.
Try it next time you travel. Buy a new fragrance for the trip, or pack a travel size of something you’ve never worn, and wear only that while you’re away. When you’re home, it becomes a souvenir you can spray. I’ve come to link Sunset Hour by Goldfield & Banks with summer evenings in the same way.
Look beyond your first impression. A gut reaction is a good start, but knowing how a fragrance is built helps you choose with more confidence. That’s where fragrance families come in, and it’s what I’ll cover next.
The short edit
The essentials: Smell reaches the brain’s emotion and memory centres more directly than any other sense, which is why a scent can move you before you’ve named it.
Ask yourself: Is there a scent that takes you straight back somewhere? What is it about that moment you’d like to feel again?
Worth knowing: Scent memories often come from childhood, and they tend to feel more emotional than memories triggered by sight or sound.
