The compound behind it can also change without the list changing.","\u003Ch2>How it works\u003C\u002Fh2>\u003Cp>Parfum is not a substance. It is one INCI term standing in for a blend of scent materials, often many, supplied to a brand as a single compound and declared under one word, because in most markets a fragrance's composition is treated as a trade secret. Where the rest of a list names things, this names a mixture, and the mixture differs from product to product.\u003C\u002Fp>\u003Cp>Some of what it covers is synthesised, some distilled or pressed from plants, and the term does not distinguish. Its job is smell: either the scent a product is sold on, or the masking of a base that surfactants, oils and some actives leave smelling unpleasant. That is why a product described as unscented can still carry it.\u003C\u002Fp>\u003Ch2>The evidence\u003C\u002Fh2>\u003Cp>Fragrance materials are among the most commonly identified causes of allergic contact dermatitis from cosmetics. That is why individual fragrance allergens have to be named separately once they pass a set level: the rule exists because the umbrella word hides the molecules people actually react to. Which molecules those are, and the level that triggers naming them, is decided by each market and has been revised more than once, so the current local rule is the one to read.\u003C\u002Fp>\u003Cp>The rest is less dramatic. Fragrance is not toxic at the levels used, most wear it without incident, and irritation depends on the dose, on the rest of the formula and on the barrier it lands on. The honest summary is a trade: it does nothing for skin and carries a risk that is small but not zero. Whether that is a bad deal depends on how much you want the product to smell of something, which is not an irrational thing to want.\u003C\u002Fp>\u003Ch2>Suitability\u003C\u002Fh2>\u003Cul>\u003Cli>Not an active; no skin type argues for its presence\u003C\u002Fli>\u003Cli>A specific reason to avoid it if patch testing has named a fragrance allergen\u003C\u002Fli>\u003Cli>A general one where skin is eczema-prone, broken or freshly exfoliated\u003C\u002Fli>\u003Cli>Fragrance-free and unscented are different claims, and the second can mean masked\u003C\u002Fli>\u003C\u002Ful>\u003Ch2>Concentration\u003C\u002Fh2>\u003Cp>No figure, and one would not travel. The level is set by the brief and by whatever safety assessment the market requires of the finished product. A fragrance strong enough to notice is not automatically a problem, and a trace used to cover a base is not automatically safe for someone already sensitised: the amount matters less than whether your skin has met that molecule before.\u003C\u002Fp>\u003Ch2>Conflicts & combinations\u003C\u002Fh2>\u003Cp>Nothing conflicts with it chemically. Two practical points. A routine can carry fragrance at every step, and exposure adds up even where no single product is heavy. And the word is stable while the thing behind it is not: a brand can change supplier or rework the compound with no visible change to the list, which is why a product can start smelling different, or start stinging, while its ingredients read as before.\u003C\u002Fp>","Parfum: the one word on a label that covers an entire undisclosed blend — what it is for, why individual fragrance allergens are named separately, and what fragrance-free actually claims.",{"faq":78,"tldr":94,"title":98,"content":99,"meta_description":100},[79,82,85,88,91],{"a":80,"q":81},"Пользы коже она не приносит, а небольшой, но реальный риск аллергии и раздражения несёт, так что это обмен, а не запрет.
