It is here that the major asset of the DECLÉOR Brand is constantly enhanced through research work conducted on new botanical species in order to extract the most active olfactive molecules, known as essential oils.
Through its unique experience and know-how, DECLÉOR's group of researchers combines "science and nature" to develop ever more effective cosmetic formulae. Every innovation produced undergoes a process of dual expertise:
More than thirty years of research have resulted in the creation of a DECLÉOR 'aroma library'. Constantly enhanced by the research work conducted on new botanical species, this unique aroma library is a source of permanent innovation: today, no fewer than 40 essential oils are used in more than 150 formulations.

Because they are so powerful, the transformation of essential oils to obtain a 100% natural cosmetic formula is extremely delicate, requiring all the technical mastery that our Laboratories have at their disposal.
When combined, Essential Oils work in synergy to naturally create new properties. This discovery lies at the heart of our AROMESSENCE™ products and is also the basis for all of the creams, balms and lotions in our various ranges.
These ranges combine the best of essential oils with the best of contemporary research on active ingredients in accordance with the benefits sought. In addition to their intrinsic properties, Essential Oils are also incredible carriers that improve the 'penetration' of active ingredients and which have the capacity to be rapidly absorbed by the skin.
The essential oils are obtained from any plant that has an olfactory power.
They can be obtained from flowers, leaves, roots or woods.
The most commonly used distillation technique is the steam distillation process.
What are the benefits of these essential oils for the skin?
The first benefit, which has been widely known for a long time, is a bactericidal power.
That is why the Egyptians used the power of essential oils to preserve bodies during the mummification.
Over time there were clinical observations about the activity of essential oils but no clear explanations were provided by those studies.
Over the past 10 years Decléor has been working on this matter to know more about the effects of essential oils on the skin in relation to a cosmetic use.
Decléor has conducted tests on essential oils, screened some essential oils in relation to certain types of actions and noticed that some of them could be effective on lipolysis, on oily skins, on skin protection against attacks and have anti-wrinkle actions – all sorts of applications which are needed for cosmetic use.
