N° 05AI Layering · Allelium

Meet Allelium.
Compose your signature.

Allelium is Maison Allélique's private AI — a perfumer that only exists for the people who hold our Grails. Tell it which Grail you wear, and it prescribes a seasonal layering Set — three fragrances in a chosen olfactory family — with the exact formula to layer it on top of your Grail.

The Thesis

A fragrance made for many is a fragrance made for no one.

Your Grail is the base — Alma, Vida or Sereno, worn alone as your voice. A Set is a season: three fragrances in one olfactory family — florals, citrus, gourmand, aromatic, oud — formulated to layer on top of your Grail. Allelium, our private AI, composes the exact proportion so the same Grail becomes a new signature every ritual.

“Your Grail is your voice. A Set is the season. Allelium is the perfumer between them.”

The Model

Allelium, alive.

Allelium is Maison Allélique's personal formulation system.

It does not recommend products. It tells you how to blend them.

Designed to understand the singularity of each person, Allelium reads your daily habits, personal metrics, skin needs, mood, season, lifestyle, and occasions to create the precise skincare routine you need and the fragrance you must compose.

As you change, Allelium changes with you. Each update in your metrics transforms your formulas, adjusting the way Maison Allélique products are blended to match your skin, your rhythm, your environment, and your emotional state.

It is your own apothecary at home: intelligent, evolving, and entirely personal, guided by the savoir-faire of our Maison in Paris.

With Allelium, personalization is no longer a choice from a list. It becomes a living formula, composed around you.

Seven signals

Allelium listens to seven quiet things before it composes.

  • N° 01

    Mood

    What the day is asking of you — before you have named it.

  • N° 02

    Weather

    Barometric pressure, humidity, wind. Scent behaves differently under each.

  • N° 03

    Biology

    Cycles, hormones, skin pH — the private weather no one else sees.

  • N° 04

    Occasion

    A first hour, a slow supper, a farewell, a promise kept in silence.

  • N° 05

    Location

    The room, the city, the altitude. A perfume worn indoors is not the same perfume outdoors.

  • N° 06

    Allergies

    What your body will not have. We compose around it, quietly, without asking twice.

  • N° 07

    Preference

    The notes you already love. The notes you have never worn. We read both.

Skincare — the evolving routine

Allelium also composes your skin.

You share a few quiet metrics — sleep, hydration, the season, the water in your city, how the skin has answered lately. Allelium reads them, and prescribes a routine of our own skincare — in the order, cadence and quantity your skin needs today.

Because the routine must evolve with you.

We are human beings. Our needs change constantly — with the season, the city, the age, the night that was and the day that comes. A single fixed routine cannot hold that. Allelium listens again each time you write to it, and re-prescribes only what has changed.

Prescribed. Not fixed. Never repeated the same way twice.

The Sets

Three fragrances. One family.

A Set is a box of three fragrances, formulated to be layered — never worn alone. Each Set belongs to one olfactory family, and each Set is issued for a season.

Any Set can be layered with any Grail. The Grail is the constant — your voice. The Set is the season on top of it. Allelium composes the exact proportion, drop by drop, for the day at hand.

  • Florals

    Neroli, rose, magnolia in rain.

  • Citrus

    Bergamot leaf, bitter orange, cedrat.

  • Gourmand

    Honeyed benzoin, dark cocoa, myrrh.

  • Aromatic

    Wild lavender, thyme in stone.

  • Oud & Resin

    Aged sandalwood, quiet oud, labdanum.

Sets are issued seasonally. Older Sets return to the register and are not reprinted.

The Ritual

No queue. No delivery. No atelier to visit.

You already hold your Grail. You tell Allelium which one — Alma, Vida or Sereno — and which Set you own. Allelium prescribes the layering: which fragrance of the Set to open, how many drops, and where on the skin to set them down, over the Grail you already wear. The ritual begins the moment the model does.

Access

Allelium is included with your first Grail.

When you take home an Alma, a Vida or a Sereno, the model is issued to you personally, bound to your register. It cannot be lent, forwarded, or resold. There is no separate purchase, and no waiting list for the app itself — the Grail is the key. Layering Sets are ordered separately, and any Set can be layered with any Grail.
