Hazelnut oil, extracted from the fruit of the hazelnut tree (Corylus avellana), is a versatile and precious product, prized for its many applications, particularly in cosmetics. This article explores the fascinating history of hazelnut oil, details its production process, and highlights its specific benefits for skin and hair.
The origins and history of hazelnuts and hazelnut oil :
Hazelnuts have been eaten by humans for thousands of years. Archaeological evidence shows that hazelnuts were part of the diet of prehistoric peoples in Europe and Asia. The hazelnut tree, a hardy and adaptable tree, grew abundantly in these regions, providing an easily accessible source of nutrition. Ancient civilisations were quick to recognise the beneficial properties of hazelnuts. The ancient Greeks believed that hazelnuts could treat a variety of ailments, including respiratory ailments. The Romans used hazelnut oil to treat wounds and moisturise the skin. Later, in the Middle Ages, hazelnut oil was commonly produced in European monasteries. The monks used the oil for its therapeutic properties and to prepare traditional remedies. Over the centuries, the use of hazelnut oil spread to cooking and cosmetics, particularly in France and Italy. Today, hazelnut oil is enjoying a revival of interest, particularly in the field of natural cosmetics. With the growing trend towards natural and organic beauty products, hazelnut oil has become a sought-after ingredient for its nourishing and moisturising properties.
Proceso de producción del aceite de avellana :
La producción de aceite de avellana comienza con la recolección de las avellanas maduras, normalmente a finales de verano o principios de otoño. Las avellanas deben estar maduras y ser de gran calidad para garantizar un aceite rico en nutrientes. Tras la cosecha, las avellanas se seleccionan para eliminar las que están dañadas o son de calidad inferior. Las avellanas seleccionadas se limpian para eliminar las impurezas. Se secan para reducir su contenido en agua, lo que facilita la extracción del aceite. Esto puede hacerse de forma natural, exponiendo las avellanas al sol, o utilizando secadores modernos. Aunque no siempre es así, algunos métodos de producción incluyen una etapa de tostado posterior. Esta técnica consiste en calentar las avellanas a una temperatura controlada para desarrollar sus aromas. Roasting gives the oil a more pronounced flavour, but can alter certain heat-sensitive nutrients. The next step is to press the hazelnuts to extract the oil. There are two main pressing methods: cold pressing (this method consists of extracting the oil at temperatures below 60°C, and preserves the hazelnuts' natural nutrients and aromas. The oil obtained is often of better quality, but yields are lower) and hot pressing (this method uses higher temperatures to increase yields. However, it can degrade certain heat-sensitive compounds, affecting the quality of the oil). After pressing, the oil is filtered to remove impurities and solid particles. It is then stored under optimum conditions before being bottled. The bottles must be opaque or made of dark glass to protect the oil from light, which can degrade its qualities.
Benefits of hazelnut oil for the skin:
Hazelnut oil is rich in unsaturated fatty acids, particularly oleic acid, as well as essential fatty acids such as linoleic acid. It also contains vitamin E and phytosterols, which are essential for skin health:
- Intense hydration: thanks to its high fatty acid content, hazelnut oil is an excellent natural moisturiser. It penetrates the skin easily without leaving a greasy film, making it ideal for face and body care. It helps to maintain skin elasticity and prevent dryness and irritation.
- Antioxidant properties: the vitamin E present in hazelnut oil is a powerful antioxidant that protects the skin from damage caused by free radicals. It helps prevent premature ageing of the skin, reducing the appearance of wrinkles and age spots.
- Sebum regulation: Hazelnut oil has astringent properties that help balance sebum production. It is particularly beneficial for oily and combination skin, as it can help prevent breakouts and clogged pores.
- Soothing sensitive skin: hazelnut oil has anti-inflammatory properties that help soothe irritated and sensitive skin. It is often used in formulations for skin prone to redness and allergies.
Benefits of hazelnut oil for hair:
Thanks to its incredible richness in unsaturated fatty acids, essential fatty acids, vitamins E & phytosterols, hazelnut oil is also highly beneficial for repairing, protecting & nourishing hair:
- Nourishment and repair: hazelnut oil deeply nourishes dry, damaged hair. It helps repair split ends and prevent breakage. Used as a hair mask, it revitalises hair and leaves it shiny and soft.
- Protection against external aggressors: the fatty acids and vitamin E present in hazelnut oil form a protective barrier around the hair, shielding it from damage caused by environmental factors such as pollution and UV rays.
- Growth stimulation: Hazelnut oil also stimulates blood circulation in the scalp, promoting hair growth. It helps maintain a healthy scalp, reducing dandruff and itching problems.
In conclusion:
Hazelnut oil, rich in history and essential nutrients, is a natural treasure with multiple applications. Its manufacturing process, although requiring special care, preserves its beneficial qualities. In cosmetics, it stands out for its moisturising, nourishing and antioxidant properties, making it a precious ingredient for skin and hair care. Hazelnut oil continues to seduce lovers of natural beauty and well-being, perpetuating an age-old tradition of care and benefits.
