History
Kyphenzé - Citrus Rex appeared in 2025 in Pierre Guillaume’s Hors-Série collection, the house’s line of exceptional opuses. Its name, as enigmatic as it is assertive, evokes kyphi, that sacred incense of ancient Egypt made of resins, aromatics and precious materials, burned during the rituals of the evening.
The perfumer’s wager is to make a statue of citrus. Where the hesperidic races by, light and volatile, Kyphenzé pushes it beyond its nature, toward spices and resins, to a hold one did not expect of a citrus. It is not about reconstructing a past, but about bringing a fragrance to life from the tension between the raw light of the citrus and the buried mystery of ancient resins.
The opening bursts in blazing citruses, pushed to the zenith of their brilliance. Spices and sage densify them, while liatris brings a hay, tobacco and coumarin facet. The base of sandarac resin, a dry, balsamic Mediterranean resin, anchors the citrus in a resinous depth that makes it hold well beyond its natural life.
In the wake of Kyphenzé, one perceives the shadow of a temple, fire, lemon trees, the rush of solar pleasure. The subtitle, Citrus Rex, says it all: a king citrus, imperial, of a solar insolence, that affirms its uniqueness without having to explain it. One of the house’s most statement-making offerings in the hesperidic register.
Olfactory pyramid
Pierre Guillaume does not publish a formal pyramid: the layout below follows the progression described in the catalogue, from blazing citrus to dry resin.
The thread is tension: the raw light of the citrus meets the buried mystery of the resins and gains an imperial hold from it.
Olfactory profile
Kyphenzé is a statement citrus rather than a fresh eau. The perfumer pushes citrus beyond its lightness, toward spices and resins, so it holds on the skin far longer than an ordinary citrus. It is an imperial citrus, solar and resinous, between ancient Mediterranean and Oriental reverie.
Its signature lies in this tension between raw light and buried mystery: the glow of the blazing citruses, the density of the spices and sage, the balsamic depth of the sandarac. Liatris adds a hay-and-tobacco facet that brings the citrus close to incense. The result is a hesperidic at once dark and luminous, diffusive and tenacious, unisex and distinguished.

Kyphenzé is a fine-weather citrus by its glow, but an all-season one by its resinous hold. Its blazing citruses make it solar in the heat, while sandarac and spices give it the depth of an evening fragrance, even in the cold.
