Essential oils are natural, volatile and scented substances produced by aromatic plants to help them grow, reproduce, and fight against insects, bacteria and viruses. They are the plants’ natural remedy that ensures their protective, reproductive and regenerative properties.

At Decléor since our creation in 1974, we have harnessed the power of essential oils knowing that they are more than an ingredient, they are an incredible gift from nature. Essential oils have powerful benefits on both skin and mind, including anti-inflammatory, antibacterial, antioxidant & anti-stress therapeutic properties*.  They are so potent that they must be selected, extracted and blended with the highest level of expertise and skill.

Nature is very selective: in fact, less than 5% of plants are able to synthetize essential oils. This is why we are passionate about essential oils and why all of Decléor’s teams and experts have spent so much time studying them one by one. It takes time & energy to discover those plants and understand how each essential oils works within them.


Like precious stones, essential oils go through different processes and need a lot of work to transform them into the skincare jewel that they are. For example, it takes 1kg of lavender to produce 5g of essential oil. Decléor is committed to promoting sustainable and renewable sourcing of plants around the world, and to selecting only the finest essential oils. 


Each drop of essential oil contains 100 to 200 active molecules. These powerful and active molecules make this ingredient an exceptional resource for active skincare. Our expert team of aromatherapists, olfactotherapists, toxicologists and formulation engineers professionally blends them, which ensures Decléor’s essential oils have the maximum skin benefits.



Essential oils have specific biological activities and mood-affecting properties. For more than 40 years, Decléor has selected and blended the most powerful essential oils, developing a unique expertise of their combined skin benefits. In 2019, we classified essential oils in families of therapeutic activities, hence sharing our exclusive knowledge in aromatherapy. Our classification table lies at the core of our formulating process and is key to navigating which range is suitable for your skin. Our products are composed with selected essential oils, which not only treat your skin but also can act on mind benefits including reducing anxiety, improving sleep and helping you to relax.

High-quality essential oils can only be derived from healthy plants grown in an optimal natural environment, with the ideal climate conditions, soil composition, and moisture levels to help them flourish.

Their quality and properties are correlated with the environment they grow: soil and weather conditions influence their composition and it is not possible to recreate them in a laboratory.
