Delphine Jelk: Bringing Skin-Enveloping Comfort to Guerlain’s Fragrances

“I like the idea of a perfume that makes you feel good: one that envelops and soothes you, giving you confidence and a sense of security.”

Delphine Jelk, from an interview with Nez

Born in 1977 in Fribourg, Switzerland.

Guerlain’s Perfume Creation Director and perfumer. Jelk, who has created many fragrances from La Petite Robe Noire to Tobacco Honey, originally studied how to make clothes.

What if the feel of cashmere or linen could also be conveyed through scent? That experiment prompted the move from fashion design to perfumery. Childhood memories, the sensation of being enveloped against the skin, and the reassurance of a moment to breathe: following Jelk’s words reveals perfume not only as an adornment that attracts others, but also as something close at hand for oneself.

A Life in Perfumery

A Small Bottle of Apricot Oil

Jelk’s earliest olfactory memory is a small bottle of apricot oil used by the mother and grandmother. That familiar childhood smell remained part of life in adulthood.

“Probably the apricot oil in the little bottle my mother and grandmother used. It is still part of my life, and now part of my four children’s lives as well.”

Delphine Jelk, from an interview with Nez

The scent of iris recalls the warm, slightly dusty air in the grandparents’ attic. Fragrance can bring back forgotten places and time spent with people. This experience would later become deeply significant when Jelk aspired to become a perfumer.

Interested in both science and art from childhood, Jelk dreamed of being an alchemist making magical potions. Pharmacy was a possibility after high school, but at eighteen Jelk’s first wish was to leave Switzerland.

“At eighteen, the only thing on my mind was leaving Switzerland. But I needed a proper reason.”

Fond of drawing and fashion, she went to ESMOD in Paris to study men’s ready-to-wear. A journey to Paris that was not supposed to be about making perfume would eventually take an unexpected direction.

A Graduation Project Turning the Feel of Clothes into Scent

In 1999, at the end of four years of study, Jelk created a collection designed for a man working from home. As the internet began to change life and work, Jelk conceived clothes made from cashmere and linen.

What mattered to her was that clothes should not be experienced through sight alone. With help from a friend who worked as an evaluator at Firmenich, Jelk created two fragrances inspired by the fabrics. Scented soy milk was also prepared, making the presentation an experience connecting several senses.

The project won an award and brought two job offers: one to make clothes at Martin Margiela in Paris, the other to research trends at Firmenich in Geneva.

Jelk chose Firmenich. Having wanted to leave Switzerland, Jelk now returned with a new possibility in sight.

Freshly Cut Grass Opens the Next Door

At Firmenich, a kind perfumer introduced Jelk to different raw materials every day. Among them was Triplal, reminiscent of freshly cut grass and green leaves.

Jelk recalled that moment in an interview with El País.

“I do not know where, but the scent took me somewhere. That was when I thought: I want to make this my work, creating fragrances that take people somewhere.”

Delphine Jelk, from an interview with El País

Like the iris that brought back the grandparents’ attic, materials became more than smells: they connected past and present. Jelk describes this effect as something like a soft toy for the soul.

Jelk subsequently joined Firmenich’s marketing and evaluation team in Paris. Yet as the desire to create grew, so did unease about not having received formal perfumery training. Jelk therefore entered the Grasse Institute of Perfumery (GIP) for specialist training.

Observing the harvesting and extraction of mimosa, rose, jasmine, and lavender, Jelk learned materials through Jean Carles’s method of contrast and memory and recreated classic perfumes. The Roure perfumery school founded by Carles is distinct from the Grasse Institute of Perfumery attended by Jelk, but the method has been passed down to later generations.

Learning Freedom from Philippe Romano

After school, Philippe Romano became Jelk’s mentor. In 2003, Jelk worked at Drom, studying under him for about three years.

“A generous, free-spirited person. My mentor passed on knowledge so that I could develop my own creativity.”

Delphine Jelk, from an interview with Nez

Jelk weighed materials and made trials personally, working not only on fine fragrances but also candles, shampoos, and products for Yves Rocher and Mixa Bébé. Jelk says that this practical experience is why making a trial remains possible even on a day when an assistant is absent.

Eventually, an opportunity arose to work in New York. A change of market also changes the situations in which a fragrance is received. Alongside that experience, a relationship with Guerlain began to develop. Romano died in the summer of 2021, and Jelk mourned the mentor in an interview the following year.

A Black Dress Born from Macarons and Sneakers

Around the time of going to New York, Jelk met Sylvaine Delacourte, who was responsible for fragrance development at Guerlain. Asked to try creating a floral scent, Jelk first proposed an orange-blossom candle.

At the same time, Jelk wondered whether Guerlain also needed a fragrance that a younger generation could regard as its own. Inspiration arrived in the form of Sofia Coppola’s film Marie Antoinette.

“Seeing Marie Antoinette in Converse sneakers eating sweets, I proposed raspberry and cherry macarons with rose. I added smoky tea and licorice to give it a slightly rock-and-roll character.”

Delphine Jelk, from an interview with Nez

A historic dress and sneakers, sweet pastries and a slightly rebellious air: Jelk sought to express that contrast through scent. Developed over about two years with Delacourte and marketing executive Ann Caroline Prazan, La Petite Robe Noire was released exclusively in Guerlain boutiques in 2009.

Following its success, a separate fragrance, Modèle No.2, appeared in 2011. It was later reintroduced as Mademoiselle Guerlain. Then, in 2012, a worldwide version based on the original was launched, with Thierry Wasser also involved.

Distinguishing the 2009 original from the 2012 rollout reveals both Jelk’s initial concept and the subsequent collaborative work.

Expressing Guerlain’s Identity in Today’s Language

Did Guerlain need a macaron fragrance? Some people reportedly reacted that way to the new creation. For Jelk, however, a sweet, enveloping fragrance did not contradict Guerlain’s tradition.

Jelk points out that Shalimar’s vanilla and Mitsouko’s peach were also bold expressions when they appeared. La Petite Robe Noire, too, connects with the Guerlinade through rose, iris, vanilla, and tonka bean.

Rather than simply repeating the past, Jelk sought to translate the spirit that had been daring in its own time into a present-day fragrance, joining respect for the house’s heritage with contemporary sensibility.

In 2014, Jelk officially became a house perfumer at Guerlain. Jelk also speaks candidly about the feelings that accompanied the change in working environment.

“Now, when I finish a perfume, I feel anxious instead, full of questions. It is very difficult to know when to call it finished. Then I wait fourteen months until the launch before finally discovering whether it will reach people.”

Delphine Jelk, from an interview with Nez

At a fragrance company, acceptance of a proposal is a moment of shared celebration. Within a house, however, the perfumers themselves must judge when a fragrance is finished and take responsibility for bringing it into the world. It was work in which freedom and uncertainty increased together.

Contrasting Materials That Support Softness

Jelk favors fragrances suggestive of roundness, powder, vanilla, almond, and milk. Combining bitter almond with coumarin and heliotropin maintains that impression from beginning to end; combining it with a raspberry note produces a cherry expression. Jelk explains these effects of materials in concrete terms.

Helvetolide, a musk reminiscent of clean skin, and rose, which can develop in many directions, are also important materials. Jelk believes that the aromatic character of lavender and rosemary comes alive when paired with round, soft elements. This sensibility can also be found in collaborations with Wasser, including Mon Guerlain (2017).

Patchouli, by contrast, is described as a difficult material that does not work well when added after the structure has been built. The later Patchouli Paris confronted that material directly.

Tobacco Honey: Dry Leaves and Enveloping Nectar

In Tobacco Honey (2023), the idea of contrast is expressed particularly clearly.

“For a long time, I wanted to combine honey and tobacco. On one side is the powdery swirl of dry tobacco leaves; on the other is sweet, enveloping honey.”

Delphine Jelk, from Guerlain’s official presentation of Tobacco Honey

What is depicted here is not cigarette smoke itself, but the multifaceted scent of dried leaves. A tobacco accord built from several materials is connected to the warmth of honey.

Artistic expression that seems to present rough materials as they are also informs the fragrance’s imagery. From a rustic subject comes a rich scent on skin. In 2024, it won the US Fragrance Foundation’s Perfume Extraordinaire of the Year award.

Néroli Plein Sud: From a Novel to the Fields of Morocco

Néroli Plein Sud (2024) was inspired by Antoine de Saint-Exupéry’s Southern Mail (Courrier Sud) and Moroccan neroli.

From Spain to Morocco, then beyond the desert: an aerial journey imagined through the novel led to an actual journey to an orange-blossom growing region. Jelk visited a farm in Khemisset, observing flowers growing in sunlight and wind.

“I wanted to recreate Saint-Exupéry’s flight over the orange groves and desert of Morocco.”

Delphine Jelk, from an interview with El País

The composition, wrapping the brightness of neroli in the heat of spices and the scent of wood, seems to move between coolness and heat. In a 2024 interview, Jelk said that its creation took about eight months.

A tribute to Jacques Guerlain’s Vol de Nuit was also part of the idea. The Saint-Exupéry edition, which also involved the Youth Foundation, was designed to evoke a travel diary.

Patchouli Paris: Making a Challenging Material the Protagonist

Patchouli Paris (2024) is set in Paris at night: music, theaters, and human warmth. Instead of erasing patchouli’s earthiness and roughness, Jelk built the fragrance from those qualities.

Jelk speaks of the image of lovers spending a night in Paris and of making a material one’s own. Iris, vanilla, sandalwood, and musk lend different forms of softness to patchouli’s contours.

Vanilla also has facets beyond simple confectionery sweetness. The tincture used by Guerlain has aspects reminiscent of spices, wood, and smoke. Using that shading preserves patchouli’s strength while making a fragrance that settles naturally on the skin.

Vétiver Fauve: Tropical Vitality

In Vétiver Fauve (2025), Jelk returned vetiver to a tropical landscape.

“I paired the warm, woody essence of vetiver with an accord of a green, humid tropical jungle, adding brightness with pineapple and fig fruits.”

Delphine Jelk, from remarks published by ScentAdvice

Rudyard Kipling’s The Jungle Book is the work associated with the fragrance. Rather than showing only dry smokiness, it seeks to convey the humidity of land where plants are alive and the light of fruit.

Rosa Verde, from the same year, combines rose with the coolness of cucumber. This, too, connects with Jelk’s interest in wearing perfume as an everyday experience that can change one’s mood.

A Small Team Supporting an Individual Creator

Although Jelk says that fragrance creation requires quiet, the work is not completed alone. In a 2025 interview, Jelk described a team that includes laboratory assistants, a technical perfumer, an evaluator, an assistant supporting the workflow, and people responsible for sourcing materials. Wasser also contributes years of experience with growing regions and relationships with producers.

Jelk’s own role included not only new creations but also reformulating about 150 existing perfumes. Continuing to make fragrances from the past also requires ongoing attention to materials and quality.

“I do not make only my own perfumes. I also make the perfumes of my illustrious predecessors.”

Delphine Jelk, from remarks published by The Fragrance Foundation France

In December 2021, Jelk was made a Knight of France’s Order of Arts and Letters. Jelk regards this as both a personal honor and a step toward recognizing perfume creation as an art.

As of 2026, Guerlain’s official materials also introduce Jelk as Perfume Creation Director and perfumer. While adding new creations to the house’s history, Jelk carries out the work of keeping that history itself alive.

An Aside…

Jelk treasures Jicky (1889), encountered at twenty, as the perfume of a lifetime. It was also a surprise to discover, later on, the beloved bitter-almond facet in this fragrance by Aimé Guerlain.

At work, Jelk plays no music, concentrating on smells in silence. At the same time, there is a habit of watching the same television series every morning since the age of eleven. Jelk says that time with something familiar gives the day a sense of reassurance.

The favorite food is pasta, and Jelk also likes the smells of butter, garlic, and basil. The most cherished olfactory memories include the smell of the children as newborns. Jelk also speaks of pleasure and intimacy in a partner’s natural smell at the end of the day.

In bespoke perfumery, Jelk has also created a fragrance for a client who wanted six daughters to wear the same scent after the client’s death. For Jelk, perfume is not necessarily replaced each season like clothing. Memories of scent that began with a small childhood bottle are being passed on to other families too.
