Perfume as Memory: How to Find a Signature Scent

Perfume is the only beauty product that is entirely about other people. It is the trace you leave in a room after you have left it. It is what your friends think of when they think of you, though they may not be able to say why. It is also, uniquely among beauty purchases, almost impossible to choose correctly in a department store, in a rush, on a Tuesday afternoon when you have twenty minutes and a department store is blasting seventeen competing fragrances at you simultaneously.

I have been interested in perfume for twelve years and I have owned, at various points, a great many bottles that were wrong. The ones that have been right — three, so far — were chosen in ways that had almost nothing to do with rational product selection.

Why the department store does not work

Olfactory fatigue sets in after the third or fourth fragrance. Your nose can no longer distinguish. The strips are useful for the top notes — the immediate impression — and entirely useless for the base notes, which are what a perfume actually smells like two hours after application, which is what a signature scent actually is. The testing environment is performative and loud. The salespeople have sales targets. None of this is conducive to the slow, attentive decision that choosing a signature scent requires.

How to actually choose

Order samples. Most independent perfume houses — Diptyque, Le Labo, Maison Margiela Replica, Juliette Has a Gun — sell sample sets of their range for ten to twenty pounds. The major fragrance sample services (Thirdman, Scentbird, The Fragrance Shop sample service) give you access to large libraries.

Wear a sample for a full day. Not on a strip, not sniffed from the bottle. On your skin, for eight hours, through coffee and lunch and the afternoon and the evening. See how it develops. See if you notice it pleasantly on your skin at hour five or if it has become something you are ignoring. See if anyone says anything about it.

The right perfume does not make you smell of something. It makes you smell more like yourself — a warmer, more particular, more present version of yourself.

On families and notes

If you know nothing about fragrance families, start with three. Oriental (amber, woods, spice, vanilla) tends to read as warm, sensual, and evening-appropriate. Floral (rose, jasmine, iris, peony) is versatile and broadly wearable. Fresh (citrus, green, aquatic) is clean and light. Most people find themselves drawn consistently to one family with variations across it — and that family is usually the starting point for a signature scent.

The note that is most consistently underrated: iris, which is not a flower smell at all but something powdery and woody and cold, like clean skin on a winter morning. If you have never tried an iris-led fragrance, try one. It surprises almost everyone who does.

The relationship between perfume and memory

The olfactory system is unique among the senses in its direct connection to the hippocampus and amygdala — the brain structures responsible for memory and emotion. Other sensory information is processed through the thalamus before reaching these areas; smell goes directly. This is why a scent can produce an emotional memory more immediately and more physically than a photograph or a piece of music. The smell of a specific perfume worn by someone you loved is not merely a reminder of them. It is an involuntary return to the emotional register of the time when that smell was present.

This neurology has implications for how we understand the project of finding a signature scent. A signature scent is not just something that smells good on you. It is the smell that people who love you will associate with you for the rest of their lives, and the smell that will carry you back, whenever you encounter it unexpectedly in later life, to the period in which you wore it. This is a more significant decision than most purchasing decisions. It is worth taking the time it requires.

The memory attachment also explains why many people's favourite perfumes are ones they have worn through significant periods of their lives — not because those perfumes are objectively better than others, but because they have been freighted with emotional content that makes them impossible to encounter neutrally. The perfume you wore when you were twenty-five and the world was very large is not the same perfume to your nose at forty that it was then. It carries the twenty-five-year-old with it. This is either a reason to keep wearing it or a reason to change — to let the current period develop its own olfactory signature rather than living perpetually in the emotional atmosphere of an earlier one.

The perfumers worth knowing

The perfume industry has a two-tier structure that most consumers are unaware of: the mainstream houses (Chanel, Dior, Guerlain, YSL) and the niche houses (Serge Lutens, Comme des Garçons, Diptyque, Le Labo, Byredo, Maison Margiela Replica). The mainstream houses produce excellent fragrances and also a large volume of mediocre ones — the profit model requires broad appeal, which tends toward the inoffensive. The niche houses produce fragrances with stronger points of view, more unusual ingredients, and a much higher proportion of genuinely interesting work relative to output.

Within the niche world, certain perfumers have consistent voices worth learning to recognise. Serge Lutens's work is characterised by an extraordinary use of unusual raw materials — the iris and violet in Un Lys, the caramel and amber in Rousseur, the incense in Five o'Clock au Gingembre — in compositions that are unapologetically complex and consistently rewarding. Francis Kurkdjian, now at his own house, creates perfumes of technical perfection that have a cleanliness and elegance that is entirely his own. Olivia Giacobetti, working at Diptyque and elsewhere, produces some of the most quietly beautiful green and floral fragrances in contemporary perfumery.

Knowing perfumers by name rather than by house makes fragrance exploration more navigable because it gives you a principle of organisation that is not commercial. You are following a creative voice rather than a brand strategy. The perfumer whose work consistently resonates with you is the creator whose next fragrance is most likely to resonate with you too. This is how collectors build a vocabulary in any art form — by developing relationships with the sensibility of specific artists rather than responding randomly to individual works. Perfume rewards this approach as richly as any art.
