Hazelnut Vegetable Oil: How is it obtained?
Hazelnut oil is derived from the nuts of the tree known as Corylus Avellana. It is extracted from the seeds. Like most vegetable oils, it is produced using a method called cold pressing. This extraction process involves several steps.
Harvesting of fruits, from August to October, or even November, depending on the year.
Cleaning through suction, drying, and hulling to isolate the hazelnuts.
Mechanical pressure grinding of hazelnuts. This step is carried out at room temperature and does not involve any chemical reactions. An unpurified hazelnut oil is obtained.
Purification of the oil through decantation and filtration on cellulose paper (no chemical reaction is performed).
This extraction method allows for the production of a 100% pure and natural oil, preserving all the active principles of hazelnuts. In other words, we also refer to it asvirgin hazelnut oil.
Take note! Always prioritize 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.

What are the benefits of hazelnut oil for the skin?
The vegetable oil of hazelnut is recognized 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 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 obstruction 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.
