On an ingredient list it is usually not something a formulator added on its own: it arrived inside an essential oil or a plant extract named higher up, and it appears under its own name because most markets require certain fragrance allergens to be declared once they pass a set level.\u003C\u002Fp>\u003Cp>It is also made industrially, and the molecule is identical either way: a nose cannot tell them apart and neither can skin, and the list does not say which you have. What it does in a product is smell, and act as a solvent, which is why citrus oils cut grease. Neither is a benefit to skin.\u003C\u002Fp>\u003Ch2>The evidence\u003C\u002Fh2>\u003Cp>Fresh limonene is a weak sensitiser. The complication is that it does not stay fresh: exposed to air and light it oxidises, and the oxidation products, peroxides formed as the molecule degrades, are considerably more sensitising than the molecule they came from. That mechanism is well documented, and it is what the declaration rule is really about.\u003C\u002Fp>\u003Cp>Two things follow. The first is that the risk is not fixed by the ingredient list. The same product is a different proposition new and half-used a year later, and how it was packed matters more than where the limonene came from. The second is that formulators have an answer, antioxidants in the formula and opaque packaging that keeps air out, and you cannot tell from outside whether it was used. Most people use products containing it for years without trouble. A minority sensitised to its oxidation products will react afterwards to small amounts, and that does not reverse.\u003C\u002Fp>\u003Ch2>Suitability\u003C\u002Fh2>\u003Cul>\u003Cli>Not an active; nothing about a skin type argues for it\u003C\u002Fli>\u003Cli>A specific reason to avoid it if patch testing has named it\u003C\u002Fli>\u003Cli>A general one where the barrier is broken, or the product sits on shaved or freshly exfoliated skin\u003C\u002Fli>\u003Cli>A product marketed as fragrance-free can still list it, because a plant extract brought it in\u003C\u002Fli>\u003C\u002Ful>\u003Ch2>Concentration\u003C\u002Fh2>\u003Cp>No figure. The level at which it has to be declared is set locally and has been revised, so the name tells you a threshold was crossed in that market, not how much is there. And the number that would matter most cannot be read off a label: how much of what is in the bottle is still limonene, and how much has turned into something more reactive.\u003C\u002Fp>\u003Ch2>Conflicts & combinations\u003C\u002Fh2>\u003Cp>Nothing conflicts with it. The pairing worth knowing about is already in the formula: antioxidants slow the oxidation that creates the sensitisers, which is one reason a citrus-scented oil so often carries tocopherol. The habit worth changing is keeping an opened bottle of a strongly citrus product for years. Age is the variable here, and it works in one direction.\u003C\u002Fp>","Limonene: the citrus terpene declared separately on ingredient lists — why it is rarely added on purpose, how oxidation turns it into a sensitiser, and why an old bottle is not the same material.",{"faq":76,"tldr":92,"title":96,"content":97,"meta_description":98},[77,80,83,86,89],{"a":78,"q":79},"Обычно не как таковой.
