Grange Beauté : nos formules et fabrications, notre différence

The art of using nature's best ingredients for beauty and well-being

Cold emulsion

To respect the exceptional quality of raw materials, Maison Jacynthe care products are made with respect, care and love.

  • Each material is subtly dosed to promote optimal skin tolerance.
  • Unlike traditional cosmetics which use hot emulsification and add a few % of active ingredients at the end of the formulation, a cold emulsification technique, exclusive to Maison Jacynthe, allows us to offer completely innovative textures, with contrasting sensations between freshness and hydration, comfort and olfactory wonder... and 100% active!

A telling example: from a gelled floral water, a complex of vegetable oils and a natural emulsifier (castor oil extract, lecithin, floral waxes), a homogeneous and stable mixture is easily formed and allows emulsions of incomparable quality (like mayonnaise). The textures vary from fluid gel to thicker Phytobaume and all meet the expectations of an honest, caring and intelligent product.

The search for a perfect synergy between the best of nature, the performance of care associated with the pleasures of the senses and respect for the environment and the individual.

Our formulas result from judicious blends, both simple and complex, between first cold-pressed vegetable oils (to retain all the active ingredients) and aromatic oils, powerful and precious allies of beauty and well-being, together forming an excellent interaction and allowing maximum absorption at skin level.


A total interactive compatibility between the products and materials chosen allows us to mix them and adjust them to the needs of the day, in the event that the skin needs an additional "boost" or on the contrary needs a lighter application.

Our treatments are specially formulated to allow for fully compatible, interactive " mix & match " combinations without the risk of product degradation or negatively interfering mixtures. Each product in our Tri-step program complements the others. Working in unison, they synergistically deliver a high-performance facial treatment. The concentration level of each product is adapted to the density of the product with which it will be mixed, which gives them 100% harmony and synergy.

Forty years of research and work have allowed the creator and formulator of Maison Jacynthe to demonstrate the effectiveness of her techniques and prove that what nature offers us is a magical gift.

Essential oils & Vegetable oils

Essential oils are lipophilic (attracted to lipids). They form a symbiotic relationship with vegetable oils. They disperse very well in vegetable oil, which not only becomes an excellent skincare product but also an active ingredient in its own right. Combining virgin vegetable oils with pure essential oils results in a ready-to-use product and allows for the creation of products for a multitude of high-quality skincare applications.

Excellent assimilation of lipids up to the dermo-epidermal barrier

Vegetable oils are naturally hydrolyzed by skin enzymes. Particularly those that facilitate the reaction of organic molecules such as vitamin B. However, vitamin B is found in high concentrations in virgin vegetable oils from the first cold pressing, which accelerates their absorption rates, carrying the essential oils to the basal layer of the epidermis. A few minutes after the anointing, blood tests show the presence of aromatic molecules in the blood. Fifty minutes to two hours after application, aromatic molecules are present in the exhaled air (ref. Biblio.: Aromatherapy exactly. By Doc. D. Pénoel/page 297 (medicine of interfaces) . Once the epidermal barrier has been crossed, the essential oils cross the basal membrane to reach the dermis. It is from the dermis that the essential oils will play their main roles. The first being to maintain or restore homeostatic activity (capacity to maintain relative stability of the ambient environment). The second relates to the aromatic components.

Physiological action at the cell level: the aromatic molecules bathe in the interstitial fluid before being diffused into the circulation to be captured by a protein which will transport them into the cell.

MJ adapts to nature

Essential oils are able to help capillary activity and tissue vitality. The blend is prepared using essential oils of various densities. It is often necessary to readjust the formulation according to crops and seasons. We blend our aromatic formulas in a base of vegetable oils (and for some products Aloe, for its moisturizing and plumping effect) in order to be able to apply the finished product directly to the skin. In this way, the product is directly and quickly absorbed by the skin, although the different essences, given their own viscosity, are absorbed at different speeds. The heavier essences that contain resins, are those that act more effectively on the quality of tissues at a deeper cellular level and are also those that take the longest to be assimilated, while the more fluid and lighter ones are easily absorbed by the extracellular fluids that play a vital role in maintaining skin balance.

For this reason, when preparing essential oil products, it is advisable to combine different essences of different densities in order to create a synergy or, using perfumery language, to achieve a "perfect harmony of high, middle and low notes."

It is from these conclusions that MJ chose to use the science of Mother Nature to address the needs of our skin, body and mind.

Aromas envelop us in an aromatic spiral of beauty, awakening of the senses and aromatherapeutic solutions.
