La Science du Parfum — every atom is real
Est. 1981
UDV Blue · Eau de toilette · 100 ml · $19.99

You already make it. Nobody can see it.

Perfume is the only beauty product a customer can't see, can't touch, can't try online. So they judge it by the one thing they can see: the price. At $19.99 that is not fair to what's inside this bottle — forty-five years of French perfumery, composed by master perfumers, made in France. You say it on every box. This is how you make it visible.

The published notes of UDV Blue — seen for the first time

Every note on your box has a molecule behind it.

Lemon, lavender, jasmine, geranium, cedar, musk. These are the real molecules that give those notes their smell — drawn atom by atom from their published structures. Nothing illustrated. Nothing invented. Drag to turn them; the geometry is the compound's own.

We show the perfumery molecules behind each note you publish — never the formula. That stays where it belongs: with your perfumers.

Top · Lemon1 / 6

Limonene

The molecule that makes lemon peel smell like lemon peel. It is the first thing your customer meets — and the first to leave.

Every atom you see is real — rendered from the compound's published structure, not illustrated.

Linalool

Lavender's calm. The same molecule breathes in bergamot and coriander — the fougère opening, in one shape.

Hedione

The jasmine heart. In nearly every fine fragrance composed since 1966 — including yours.

Geraniol

Named after the geranium; a rose petal keeps the same molecule. Soft, green, a little honeyed — the floral bouquet your description promises.

Cedrol

The heart of cedarwood. Dry, soft, patient — it is still on the skin past midnight.

Galaxolide

Clean skin, fresh linen. The musk of modern perfumery, and the reason a shirt still smells of you the next morning.

The question every shopper asks online

"Does it last?" — now you can show them.

Drag the timeline. Molecules leave the skin in scientific order: the light ones lift off in minutes, the heart holds for hours, the base stays past midnight. It is the number-one objection to buying fragrance online — answered on the page, honestly.

In the air. Lemon and lavender open the fragrance — this is what the tester strip smells like right now.

On the skin. The top has lifted; jasmine and geranium carry the fragrance through the morning.

What stays. Cedar and musk — the trail on the collar tonight.

◆ Top — minutes ◆ Heart — hours ◆ Base — past midnight

Order follows volatility class (top / heart / base) — the perfumery-standard simplification. Exact timings vary with skin, weather and dose.

La science s'imprime

By morning, only the memory remains.

And every memory has an address. The science proves the perfume; Paris proves the house — the one thing no one else can put in a bottle.

Le petit Paris d'Ulric

Cette carte est réelle.

Every piece of this city carries one of the molecules you just met. Tap one and it tells you which note it is, and where the structure came from.

And it stands up for real: scan the code, and Paris is on the table in front of you.

La science du parfum

Every atom is real.
So is the price.

Master perfumers, made in France since 1981, the same molecules as fine perfumery — you say it on every box. Now the customer can see it.

Where this came from. Every molecular structure on this page is taken from PubChem, the public chemical registry of the US National Institutes of Health — each molecule is shown with its own CID so you can look it up. Geometry is energy-minimised with RDKit (ETKDGv3 + MMFF94); nothing here is drawn by hand. The note pyramid is the one your house publishes for UDV Blue. Le Petit Paris is original illustration made for this presentation. We show the molecules behind your published notes — never a formula.
