Everything you need to know about hazelnut oil.

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.

Hazelnut vegetable oil is recognized for its ability to regulate sebum production and balance the hydrolipidic film. Non-greasy and non-comedogenic, it quickly penetrates the epidermis. It is considered a dry oil; it is particularly recommended for combination to oily skin as well as acne-prone skin and/or skin with blackheads. Furthermore, the linoleic acid it contains prevents the excessive accumulation of dead cells on the skin's surface. This is an essential fatty acid that promotes cell renewal, thus preventing the clogging of hair follicles that leads to comedones.

Rich in omega-6 and omega-9, it also providesnutritionandelasticityto the skin, andprevents dehydrationbystrengthening the barrier functionof the epidermis. The hydrolipidic film improves the resistance of the stratum corneum against external aggressions and limits insensible water loss.

Hazelnut vegetable oil can also be used as a massage oil. Thanks to its softening properties, it can help reduce the appearance of cellulite and stretch marks.
