How is hazelnut oil produced?

Hazelnut oil is derived from the nut fruits of the tree known as Corylus Avellana. It is extracted from the seeds. Like the majority of vegetable oils, it is produced using a method referred to as cold-pressing. This extraction process involves several stages.

1. Harvesting of the fruits, from August to October, or even November depending on the year.

2. Aspiration cleaning, drying, and hulling to isolate the hazelnuts.

3. Mechanical pressing of hazelnuts. This step is carried out at room temperature and does not involve any chemical reaction. We obtain an unpurified hazelnut oil.

4. Purification of the oil through decantation and filtration on cellulose paper (no chemical reaction is performed).

This extraction method allows us to obtain a 100% pure and natural oil, preserving all the active principles of hazelnuts. In other words, we also refer to it asvirgin hazelnut oil.

Note! Always favour virgin hazelnut oil that is certified organic. This way, it will not have undergone any chemical reactions such as refining (injection of sodium hydroxide followed by phosphoric acid to remove phosphates). Several studies have shown that the content of phospholipids in hazelnut oil is higher in the virgin material than in the refined substance.

The vegetable oil of hazelnut is recognised for regulating sebum production and rebalancing 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 types as well as skin prone to acne and/or 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 blockage of hair follicles that leads to the formation of comedones.

Rich in omega-6 and omega-9, it also providesnutritionandelasticityto the skin, andprevents dehydrationbystrengthening the barrier functionof the epidermis. As a reminder, the hydrolipidic film improves the resistance of the horny layer against external aggressions and limits insensible water loss.
