How is hazelnut oil used?

Formerly known as "hazel", the hazel 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. Virgin hazelnut oil is extracted by first cold pressing of the fruits followed by a filtration on cellulose paper. It is fluid and light, with rapid absorption and provides a dry touch. It leaves the skin matte, soft and comfortable, without a greasy film.

The biochemical composition of hazelnut oil is notably similar to that of human sebum (with a high content of omega 9 or oleic acid), making it highly tolerable and effective in regulating hyperseborrhea. Thus, it purifies skin and hair that tend to be oily.

Hazelnut oil is also used to care for dry and dehydrated skin and hair. Indeed, it strengthens the hydrolipidic film, the protective layer of the skin against external aggressions. By forming an impermeable barrier, the hydrolipidic film prevents the multiplication of harmful bacteria that can cause inflammation. It also maintains the skin's natural hydration, necessary to ensure its suppleness and softness. Like the skin, hair needs a protective layer to prevent dehydration, which leads to split ends and breakage.
