Your sillage: someone's migraine, or someone's meltdown
Japan calls other people's perfume pollution. TikTok calls it cancer. Which one is closer to the truth?
In June, an udon shop in Beppu, Japan, put a note on its door: no strong fragrance inside, guests came for the broth, not for you. Japan has a word for this — kogai, “smell pollution”, and it already turns up on government posters. In a study of 7,245 Japanese adults, 7.5% reacted to chemical scents physically: headaches, nausea, shortness of breath. So in an elevator your Baccarat Rouge 540 isn't only your business: spray once, not five times.
What the research on volatile compounds actually found
TikTok will tell you perfume on your neck hits your thyroid and ends in cancer; The Times lined up the experts who took that apart. A 2025 review in Frontiers in Toxicology does link phthalates and volatile organic compounds (the stuff that evaporates out of the liquid into the air) to allergies, but what it's talking about is air fresheners, candles and laundry products. In Japan, most kogai complaints are about fabric softener too. Shaming a person over a bottle is fashion, not science.
The question isn't how you want to smell. It's how much of you everyone else has to breathe.
The compromise showed up back in 2006. Geza Schoen built Molecule 01 out of one molecule, Iso E Super — a woody smell you only catch up close. The FT called it “the original anti-fragrance”, and that's what etiquette without rules looks like: your scent stays within arm's reach. If they can smell you from down the hallway, that's not perfume, that's a statement. Vote: rules or manners.
