Part 3 zooms out: how fragrance interacts with the body and memory, the scale of the global industry, and why sustainability is no longer optional for houses that want to source the ingredients they depend on.
Notes on Fragrance — Complete Series
8. Fragrance and the Human Body
Skin ChemistryWhy does the same perfume smell different on different people? The answer is skin chemistry.
Your skin’s pH, natural oils, body temperature, and microbiome all interact with fragrance molecules and alter how they develop. A citrus top note that disappears in minutes on one person can linger for an hour on another. An oud base that smells powerfully smoky on one skin smells warm and woody on another. This is why a friend’s recommendation, however well-intentioned, is only a starting point.
Diet is often said to play a role too, though the specific claim that high-fat diets make a fragrance project harder is one I have not been able to trace to any controlled study. What is easier to observe is that hydrated skin holds fragrance longer than dry skin. Applying unscented moisturizer before spraying creates a base that extends wear noticeably.
Scent and MemoryThen there is the scent-memory connection. The olfactory system connects directly to the hippocampus and amygdala, the brain’s memory and emotion centers. No other sense routes this way. This is why a smell can trigger a fully formed emotional memory in an instant, without conscious thought.
DS & Durga’s Radio Bombay does this to me every time. One spray and I am back in my grandmother’s home in Chennai, the smell of her sandalwood chest in the corner of the bedroom. I have not been in that room in decades. The fragrance puts me there in seconds. When I smell Ralph Lauren Polo Green, I think of my father. Chanel No. 5 will always remind me of my mother. These associations formed on their own, quietly, over years. I never chose them.
Some perfumers design with this intentionally, structuring a composition around the associations they hope it will lay down. Frédéric Malle’s house exists to give perfumers the room to work that way: Dominique Ropion took Carnal Flower through 690 iterations before it was signed off. That is the ambition at the highest level of the craft.

9. Fragrance and the Global Economy
The NumbersThe fragrance industry is large, growing, and structurally important to multiple sectors.
The global perfume market is valued at around $60 billion in 2025 and is projected to approach $100 billion by the mid-2030s. This figure covers personal fragrances only. It excludes scented household products, room fragrances, and personal care products with added scent, which would more than double the number.
Key PlayersThe dominant players are familiar: LVMH (which owns Dior, Givenchy, and Maison Francis Kurkdjian, among others), Chanel, Coty, Estée Lauder, L’Oréal, and Puig. Behind them, a tier of independent ingredient suppliers, Givaudan, dsm-firmenich (formerly Firmenich and DSM), IFF, and Symrise, essentially supply the raw materials and aroma chemicals that the entire industry depends on.
The fastest growth is happening in Asia-Pacific, particularly India and China, as disposable incomes rise and personal grooming becomes a higher priority. The Middle East is widely described as the highest per-capita fragrance spending region in the world, though I have not found public data that establishes it. On total market value the lead sits with Europe rather than North America.
Fragrance is also one of the most recession-resilient luxury categories. An $80 bottle of perfume is still an accessible indulgence for people who cannot afford a $5,000 handbag.
Must-Know FragrancesTwo fragrances worth knowing in terms of commercial scale: Creed Aventus and Dior Sauvage are routinely cited as among the best-selling niche and designer fragrances in the world respectively. Dior Sauvage has been reported to be one of the top-selling men’s fragrances globally for several years running, though rankings of this kind rest on proprietary retail panel data that is never published in full. Creed Aventus commands a price point and following that most niche houses can only aspire to. Both are worth smelling regardless of whether you own them. They became what they are for a reason.
Frederic Malle is worth a separate mention here. His house, founded on the concept of giving named perfumers creative freedom, produces some of the most serious fragrances made today. Portrait of a Lady and Monsieur are two of the best things in my collection. The people behind the Frederic Malle counter are among the most knowledgeable in the business and worth getting to know.
10. Sustainability & the Future
The fragrance industry has a genuine sustainability problem, and the better houses are beginning to address it seriously.
Endangered IngredientsSome of fragrance’s most important naturals are under pressure. Indian sandalwood is assessed as Vulnerable in the wild and its harvest in India is controlled by the state rather than by whoever owns the land; a wild tree needs something like thirty years before the heartwood is worth cutting. Agarwood, the source of oud, is scarce enough in the wild that every species of Aquilaria and Gyrinops has sat on CITES Appendix II since January 2005, with Aquilaria malaccensis listed a decade before that. Ambergris, the waxy substance from sperm whales that produces one of perfumery’s most prized fixatives, is now largely replaced by synthetic ambroxan — for legal reasons as much as ethical ones, since the sperm whale is on CITES Appendix I and has been listed as endangered under United States law since 1970. The industry’s reliance on slow-growing, rare, or animal-derived materials is a structural vulnerability.
Responsible SourcingSome houses are beginning to address this with real commitment. Chanel is long reported to work directly with flower growers in Grasse, the region whose perfume-plant cultivation UNESCO inscribed as intangible cultural heritage in 2018, though the house itself publishes almost nothing about how the arrangement works. Givaudan and dsm-firmenich both publish sustainability reports detailing ingredient sourcing practices.
The most ambitious example in the industry right now is Amouage’s Wadi Dawkah project. Since 2022, Amouage has been the custodian of Wadi Dawkah, a UNESCO World Heritage Site in the Dhofar region of Oman, home to a wild stand of Boswellia sacra whose size is usually given as around 5,000 trees, a figure that recurs across press coverage but that I could not match to any published count. In partnership with Oman’s Ministry of Heritage and Tourism, they have turned the site into what the house itself calls the first smart forest in the GCC, using geotagging and blockchain to trace every harvest from tree to bottle. That description is Amouage’s own and I have not been able to verify it independently. A visitor centre and distillery, designed by Milan-based Giò Forma Studio, is under construction and expected to open in 2027.
Perfumers are invited to sponsor individual trees at the site. I have sponsored one myself.

Similar programs exist elsewhere. Louis Vuitton runs its perfume operation out of Les Fontaines Parfumées in Grasse, though I could not find a published account of what its sourcing there actually commits to. Givaudan buys through a programme it calls Sourcing4Good, with a 2030 target for responsibly sourced materials and services. These are still the exception, not the rule, but the pressure is growing.
The Packaging ProblemThis is where the industry has the most obvious room to improve, and the least excuse not to. A typical luxury fragrance bottle arrives inside a box, wrapped in tissue, cushioned with filler, sealed with a ribbon. The bottle itself is often glass that weighs more than the liquid it contains. Almost none of it needs to be this way.
Some houses are starting to offer refill programs, selling a refill bottle or pouch instead of a whole new presentation each time. This is a meaningful step. But refills remain the exception rather than the rule.
There is a compelling model in adjacent industries worth adopting more widely. Card companies like Botanical PaperWorks embed wildflower seeds in their paper packaging. The packaging itself becomes something you plant rather than discard. Fragrance houses could easily use seed-embedded paper for outer boxes. Some smaller niche brands already do. The barrier is a willingness to prioritize it, not technology or cost.
Other practical approaches worth wider adoption: biodegradable filler materials, minimal single-material packaging that is easier to recycle, concentrates that reduce liquid volume and therefore shipping weight, and glass standardization that makes bottle reuse more practical.
The consumer side of this equation matters too. Buying fewer bottles of better quality, using what you own before adding more, choosing houses with transparent sourcing and refill programs. A collection of 850 bottles, I will freely admit, is not the most sustainable position. But it starts with knowing the problem exists.
