Formerly known as "hazel," the hazelnut tree (Corylus avellana) is a tree belonging to the Betulaceae family, primarily cultivated in Europe, Asia Minor, and North Africa. The hazelnut is the oilseed fruit that contains the highest lipid content. A recipe extracted from the Cambrai bible in the 12th century recommended the use of hazelnut oil mixed with chervil juice and honey to combat hair loss and promote regrowth. Hazelnut oil, known for its softening properties, has a remarkable ability to spread and penetrate, making it an excellent carrier in aromatherapy.
The virgin hazelnut oil is extracted by first cold pressing of the fruits followed by a filtration through cellulose paper. It is fluid and light, with quick absorption and provides a dry touch. It leaves the skin matte, soft, and comfortable.
Hazelnut oil is rich in fatty acids essential such as the linoleic acid (omega-6), the acid oleic (omega-9), the palmitic acid and the stearic acid. As a reminder, oleic acid is the most abundant long-chain monounsaturated fatty acid in our body. Highly nourishing for the skin, it makes it more supple and softer but also more radiant. Hazelnut vegetable oil also contains a natural antioxidant, the vitamin E, also called tocopherol, as well as phytosterols.
It exhibits alow comedogenicity index, meaning it does not clog pores and quickly penetrates the skin. Even though it is relatively resistant to oxidation, it is best preserved in a cool place, away from heat and light in an amber bottle.
