How to Tell If a Fragrance Is Authentic

The counterfeit problem in fragrance is real and it is large. So is the amount of confident, wrong advice about how to spot one. A good deal of what circulates will make you reject perfectly genuine bottles, and almost none of it helps with the situation most people are actually in.

What does not work

"The box feels cheap." Packaging quality varies by production run, market and year. Counterfeiters have also been copying boxes competently for a decade. This tells you very little in either direction.

"The cellophane is loose." Genuine bottles are wrapped by machine, and machines vary. Tight, neat cellophane is a thing counterfeiters are specifically good at, because they know people check it.

"The batch code isn't printed on the box." Some houses print it, some emboss it, some place it only on the bottle, and some move it between markets. A missing code on the box is weak evidence at best.

"It doesn't last, so it's fake." This is the most common false positive there is. Reformulations are constant, skin chemistry is real, and plenty of genuine fragrances are simply weaker than their reputation.

What actually works

Where you bought it. This is not a clever test, but it is by far the strongest signal. An authorised retailer, a department store, a pharmacy chain — the supply chain is the verification. Most counterfeits enter through marketplaces where anyone can list, and no amount of bottle inspection substitutes for not buying there.

The codes should agree. Where a house prints a batch code on both the box and the bottle, they should match. A mismatch is one of the few genuinely strong signals, because it usually means a real box has been paired with something else.

The price, reasoned properly. A discount is not suspicious; a 70% discount on a current-season release from an unknown seller is. Grey-market stock, discontinued lines and older batches are all legitimately cheaper. Ask which of those explains the price, and be wary if none of them do.

The drydown, not the opening. This is the definitive test and it takes a day rather than a minute. Counterfeits are formulated to pass the first ten minutes, because that is when people smell them in a shop. They fall apart in the base. Wear it a full day and compare against the same fragrance sprayed at a counter — the opening may track, but the drydown will not.

Why a decant is a different question

Every test above assumes a bottle in your hands. Buy a decant and you never see one, so none of it applies. The bottle was inspected, or wasn't, by someone else.

That means the thing you are actually assessing is not the fragrance. It is the decanter. And the questions worth asking are different:

Do they say where the bottle came from? Vagueness here is the whole tell. "Sourced from trusted suppliers" is not an answer.

Is there anything to trace? A sticker with a number on it proves nothing. A code that can be checked — that decodes to something real and fails when you alter a character — at least means fills are tracked and a specific vial can be traced back to a specific source bottle.

Do they encourage you to compare? Anyone confident in their source will tell you to go and spray the real thing next to theirs. Anyone who isn't, won't.

Are the policies specific? Real returns and withdrawal terms state where your rights end as well as where they begin. Operations with nothing behind them keep policies vague, because they never intend to honour them.

Where we stand on this

We buy full-size, factory-sealed bottles from authorised European retailers and decant them by hand, and every decant ships with a batch code carrying a mathematical check character — alter one character and it fails. You can put a code into the checker and watch that happen.

What that proves is traceability: which fill, which week, which source bottle. It does not prove authenticity by itself, and we are not going to claim it does. The honest test is still the one above — wear ours next to a department-store spray for a full day and see whether it tracks. We actively encourage that, which is not something a business selling counterfeits would do.

If you want the process itself, it is written out step by step.
