- The cryo-extract of the flower is 71 times more effective than vitamin E phosphate for cellular differentiation, adhesion and hydration at the epidermal level.

- The thermo-extract of the fruit is 61 times more powerful than vitamin C in increasing collagen I synthesis in the dermal matrix.

- The bio-enzymatic sap extract is 41 times more effective than niacinamide and stabilized vitamin C on epidermal youth parameters (differentiation, adhesion, hydration).

- At a dermal matrix level, the bio-enzymatic extract is 2.51 times more powerful than retinol on collagen I synthesis and 1.51 times more powerful that retinol on hyaluronic acid synthesis.

This temple of biodiversity, ideal for flowers to blossom in, was developed in stages, without upsetting the natural land: the soil was purified, trees were planted, hedgerows and lakes were formed, and endemic species and plants encouraging pollination were introduced.

Without using chemical fertilizers or pesticides, it is maintained on a daily basis by a community of enthusiasts – rose growers, agroecologists and landscape gardeners who are devoted to this sustainable setting that is 100% Dior.
This setting has been designed so that the roses blossom and reveal themselves in optimum conditions.

In 2022, guided by cultivation methods that are increasingly respectful of the plant and the environment, Dior science set up a laboratory at the heart of its garden with a mobile extraction unit.

This device enables the direct transformation, on site, of fresh petals, which will be at the heart of the new active ingredient in Dior Prestige La Crème.
The freshness of the petals is therefore guaranteed, preserving all the molecular richness of the Rose de Granville.
Rosapeptide’s 4 active ingredients (rose fraction, rose sap and 2 bio-peptides) have been selected for their complementary actions at each stage of collagen synthesis in the skin. Combined in the same complex, their effectiveness on collagen I, an essential protein for skin’s density and elasticity, is increased.
At the skin barrier level,
Rosapeptide significantly strengthens the integrity of the skin barrier1 by stimulating:
- the synthesis of lipids, the true protectors of the skin against external aggressions
- the synthesis of ceramides, which guarantee cohesion in the barrier

At the epidermal level,
Rosapeptide increases a marker for cellular renewal by +69%1 and multiplies aquaporin 3 activity by 201 for optimum hydration and plumper skin.

Lastly, Rosapeptide increases epidermal thickness, a sign of younger skin, by +19%1.


At the dermal matrix level,
Rosapeptide multiplies collagen I synthesis by 31 for firmer, denser skin.

LabSkin is a French start-up created in 2014. At the Edouard-Herriot Hospital (Lyon 3rd arrondissement), Amélie Thépot, a doctor of cellular biology, reproduces skin models that are as close as possible to human skin, with the help of a patented 3D bioprinting technology. LabSkin created a skin model reproducing the impact of chronic aggressions on cutaneous structures to understand how to try and reverse them.

THE FIRST1 COSMETIC ROSE FACETED
FOR SKINCARE, WITH EXCEPTIONAL EFFECTIVENESS
The queen of flowers has made her mark on the House of Dior, but only one – the most extraordinary of all – infuses the Dior Prestige skincare line: the Rose de Granville. It possesses an exceptional life force and a unique power of resilience that gives it, twice a year, the ability to be reborn. A gem shaped by nature, and progressively faceted by science.

The constant patience and exacting standards of the genius rose grower and breeder Jérôme Rateau led to the creation of a unique1 rose, the Rose de Granville. This one, out of 40,000 others, is graced with an extraordinary genetic heritage: from its stem to its petals, the Rose de Granville boasts a phytochemical wealth of over 120 molecules.

A MOLECULAR RESERVOIR OF YOUTH,
WITH PROVEN SUPERIORITY
Fascinated by its extraordinary vitality and unprecedented capacity for resilience when faced with the most extreme types of stress, Dior science continued trying to unlock the secrets of the Rose de Granville’s power, which surpasses that of the most well-known roses.1. From the stem to the flower, via the bud and the fruit, Dior science identified state-of-the-art extraction processes that respect the plant, to capture the molecular powers of the different organs of the Rose and deliver them to the skin.

Today, the Rose de Granville’s active ingredients demonstrate their superiority over the benchmark molecules in preserving youth.

Because a floral gem such as this one requires an exceptional setting and care, in June 2021, Dior gave it the new Dior Rose Garden, the House’s first rose nursery, committed to regenerative cultivation1.

A NEW, REGENERATIVE SETTING:
THE DIOR ROSE GARDEN
Located in the Granville basin, just 20 km from the Villa Les Rhumbs and the cliffs of its wild ancestor, the Rose de Granville is cultivated at the very roots of its genesis. On 20 plots spread across 7 hectares, more than 32,000 rose bushes are already growing, and by 2023 there will be over 50,000.

The creation of the Dior Rose Garden illustrates the House of Dior’s profound commitment to preserving the existence and the richness of the living world.

Accompanied by Biosphere, specialists in agroecological transitions, the House of Dior is designing a project for the future. Beyond organic cultivation directly in the open ground, a 3-year research plan was created to develop the first regenerative cultivation1 for and around the rose. Like all the Dior gardens and suppliers, by 2023, the Dior Rose Garden will be certified by the UEBT (Union for Ethical BioTrade), of which Dior is a member.

This new type of cultivation aims to have a measurable impact on biodiversity, the health and richness of the soil, its resilience, as well as its capacity for capturing carbon and its aptitude for preserving all the richness of the Rose de Granville.

A LABORATORY OF THE LIVING WORLD
DEDICATED TO THE ROSE
More than a garden, the Dior Rose Garden is a place of innovation and transmission of knowledge.
The Rose de Granville is cultivated in the open ground, under the constant supervision of Nicolas Sambet, the garden’s horticulturalist-nurseryman.
He was trained by the creator of the Rose de Granville, Jérôme Rateau, respecting the ancestral expertise inherited from André Eve, a pioneer in rose cultivation.

From 2022, the Dior Rose Garden will be transformed into a laboratory of the living world to develop a new active ingredient.
