Decléor is a more than 40 years old brand, founded by a team made up of a physician, a shiatsu teacher, an aroma therapist and a cosmetics expert. The original name of the company - CLEOR - is a reference to Clé en Or, a "golden key" that opens the door to beauty.

Decléor creates products on purely natural basis, with no colourants or conservants. One of these product lines, Aromessence, is now the brand's most popular one. Decléor promotes a holistic approach to beauty, making use of aromatherapy and natural ingredients.
