Hazelnut oil

hazelnut oil

Hazelnut oil is pressed from hazelnuts, those delicious brownish goodies that make our pralines nutty and aromatic. Its oil is rich and flavorful with a nutty aroma, which makes it ideal for gourmet dishes. It is used extensively in low-temperature cooking. Many may not know that hazelnut oil can also be used as a beauty oil to take care of skin and face. It is an efficient emollient with superior moisturizing power and can be used for various purposes other than just making chocolate truffles with it. 


The source of hazelnut oil is hazelnut. Most trees of the genus Corylus bear edible nuts, and all of them are technically called hazelnut. But in actual usage, Corylus avellana nuts receive the distinction of being used in confectioneries around the world. It is native to Europe and can be spotted anywhere from England to Iran. But, most of the commercial production is concentrated in Turkey. 

  • These nuts have been found in archaeological remains in Scotland, about 9000 years old. They were roasted, which shows that humans back then used to process seeds and nuts and eat them (well, who wouldn’t, they are so delicious!). The oil can be obtained using three ways. Therefore, there are three types of hazelnut oil. Cold-pressed oil – Cold pressing roasted seeds obtain this. It becomes virgin hazelnut oil and possesses the most therapeutic benefits. 
  • Solvent extraction – A chemical is used to increase oil extraction from the roasted seeds, mainly hexane. Such oil is often of lighter consistency and has a lesser aroma. As we shall see later, a major class of healthy fats called phospholipids gets lost from hazelnut oil because of some light filtering.  
  • Supercritical Carbon Dioxide Extraction – Oil is extracted using supercritical carbon dioxide. This is the most advanced technology which yields the highest amount of oil.  

As far as the health benefits are concerned, cold-pressed oil is the best. 

Color, Taste, and Aroma

Hazelnut oil has a golden yellow color but is not very bright. Its taste is very much like hazelnuts, and its aroma is strongly nutty. As a result, it can stimulate appetite. Some products with less aroma may be lightly filtered and not cold-pressed, which may have taken out some of the aromatic compounds that are volatile.  


Hazelnut oil has few properties, but they are impressive. 

  • Emollient – It is an excellent moisturizer for the skin. This property is bestowed upon oleic acid (omega-9), preventing moisture from evaporating from our Skin’sSkin’s surface.  
  • Anti-inflammatory – It reduces inflammation both topically and internally. 
  • Antioxidant – It prevents the body’s cells from free radical damage. This helps to keep the skin smooth, elastic, and healthy. [1] 
  • Astringent – It mildly constricts the Skin. This effect is beneficial for people with oily skin. [5]  
  • Scar Healing – Hazelnut oil can be used as a base oil for healing scars.  

Health Benefits and Uses

Hazelnut oil for Skin

Hazelnut oil makes a wonderful all-purpose skincare ingredient. It is incredibly effective at these tasks because of its hydrating and moisturizing properties. 

  • It is an excellent make-up remover. So, one can quickly remove the product on the face or Skin and begin with the cleansing process.  
  • It helps to get rid of oily skin. It may be counter-intuitive as one may think -how can an oil reduce oiliness on the skin. This is because it is a mild astringent. It constricts the Skin and shrinks the pores. This prevents sebum (body’s natural oil) from being released in high quantities. Sebum production is our body’s natural process, but too much of it makes the skin look oily and shiny, which is sometimes undesirable. 
  • Hazelnut oil makes an excellent after-shave oil for men and women. Apply it after the shave to prevent burning sensation, irritation, and razor burns. It constricts the skin pores and coats the skin, making it smooth. Its anti-inflammatory activity takes care of any redness due to a quick shave. 
  • Hazelnut oil makes the Skin glossy but not greasy. This is an excellent advantage as it can be used singly as a toner for the face if you want a good, glossy look. 
  • It provides antioxidants and Vitamin E to the Skin. This prevents it from free radical damage and premature aging. Besides being a powerful antioxidant, Vitamin E also protects the skin from UV damage but to a minor extent. We know that these rays of the sun are primarily responsible for premature wrinkles on the Skin. So, hazelnut oil would aid our body in delaying sun-induced damage, called photoageing. [6] 
  • As a body oil – Hazelnut oil’s lightness, easy flowing nature (because of low viscosity), and richness of oleic acid makes it an efficient body oil to be used right after a shower. When the body is wet, apply only the requisite amount of hazelnut oil all over. Then the Skin should be left to air dry. This treatment, when done regularly, leaves the skin soft and silky to touch, which is very desirable. Another oil that is even more prominently used in body oil formulations is sesame oil.  

Hazelnut oil for hair

Just like the Skin, hazelnut oil makes an easy to apply hair care oil. It is used in hair oil formulations. One can use hazelnut oil for these purposes. 

  •  As a hot oil treatment – Hazelnut oil mixed with olive oil makes an excellent hot oil treatment. It conditions the scalp and hair roots, making them stronger, smoother, and shinier. It imparts a nutty smell to the hair too. One can do this hot oil treatment once a week to get healthier hair. However, cold-pressed oil may have too strong an aroma, so that should be taken into account.  
  • Split Ends – After the shower, massage a small amount of hazelnut oil to the tips of hair strands. This takes care of split ends. 

Hazelnut oil and acne

Hazelnut oil is not suitable for use on active acne. It has a comedogenicity score of 2 (on a scale of 0 to 5) which means it is moderately comedogenic. It implies that this oil can clog pores and aggravate acne. People who suffer from acne should go for low comedogenic or strictly non-comedogenic oils, like jojoba oil or sunflower oil. 

However, it is good for dealing with acne scars. One can use it as a base oil and add a few drops of scar healing essential oils like helichrysum essential oil and tamanu oil. Apply this only on acne scars (as a spot treatment) and, for that matter, any scars.  

Hazelnut oil for Heart Health

Hazelnut oil resembles olive oil in terms of its nutrition. It is high in unsaturated fats, predominantly loaded in oleic acid (which is a MUFA). If consumed in moderation, it can have cardioprotective effects and possibly lower LDL cholesterol levels in the blood. This has not been proven, although it is presumed that hazelnut oil is a heart-healthy oil.  

Although the number of modern studies on hazelnut oil’s health benefits is few and far fetched, one very recent (2017) study has highlighted that it can increase HDL cholesterol in our blood, increase the total antioxidant power in our body and also decrease the alteration of a specific gene called ADRB-3 which plays a critical role in managing our body’s weight. [1] This effect was found when folate-rich foods were also eaten, like pulses. So, there may be synergy at work with folic acid.  

Hazelnut oil in cooking

The oil is mainly used for low-temperature cooking, not for deep frying. This is because of the high concentration of oleic acid, which disintegrates at higher temperatures. Secondly, hazelnut oil is excellent for drizzling on salads and snacks. It is also used by some renowned food outlets in their dips to impart an irresistible taste.   

But its most prominent use is in bakeries, where it is added to biscuits, cookies, and cakes. There are hardly any traditional recipes in which hazelnut oil is used as an ingredient, even in countries where hazelnuts are cultivated in huge quantities, like Italy and Turkey. This is because most of the nuts are used directly in recipes, like cakes and chocolates. So, only the poor-quality nuts are left for expelling the oil. Even now, the nut is much more popular and demanded than its oil. 

If you do not have hazelnut oil, then for salads, walnut oil may serve as a substitute but only to some extent. Hazelnut has its unique aroma, which it renders to the salads. For light cooking, olive oil may be safely substituted in the absence of hazelnut oil.    

Nutritional and Medicinal Information

The nutrition facts of hazelnut oil are characteristic of healthy, edible oil. It is composed mainly of fatty acids, with unsaturated fats making a huge portion of it. Hazelnut oil does not have much variety in terms of fats. Of the 100 gm of hazelnut oil, this is the broad profile of fatty acids. 

  • Saturated Fats – 7.4 gm 
  • Monounsaturated Fat (MUFA) – 78 gm 
  • Polyunsaturated Fat (PUFA) – 10.2 gm 

In depth fatty acid profile of organic hazelnut oil. 

Fatty acid Carbon notation Composition in oil 
Stearic Acid C 16:0 (Saturated fat) 4-7 
Palmitic Acid C 18:0 (Saturated fat) 1-4 
Palmitoleic acid C 18:1 (MUFA) 0.4 
Oleic acid C 18:3 (MUFA) 70-90 
Linoleic acid C 18:2 (PUFA) 7-15

The high amount of oleic acid is quite beneficial, as it is rich in heart-healthy MUFA (monounsaturated) fat. But, because of its similarity to olive oil, it is often used as an adulterant. Besides healthy fats, it provides a good enough amount of Vitamin E. 100 gm of oil provides about 47 mg of Vitamin E in the form of alpha-tocopherol, which makes it qualify into the list of foods that are rich in Vitamin E. [3] It is an important antioxidant, especially for protecting the nerves. Thus, it is quite beneficial in neurodegenerative conditions.  

Organic cold-pressed hazelnut oil contains a small number of phospholipids (about 286 ppm) that get lost during basic filtering. These phospholipids are essential for enhanced moisturization provided by the oil. [4] This shows that basic processing may shunt some micro-nutrients, which may be very important for specific therapeutic actions. This goes for other edible vegetable oils too. A lot of the quality of any oil depends on the quality of the products used and the processing techniques employed.

Side Effects and Toxicity Issues

It is considered a safe and non-toxic oil. However, it is prone to rancidity.  

Buying and Storage

It should be purchased from a reputed manufacturer because other nuts may be used to expel oil and passed off as hazelnut oil. It has a shelf life of about one year, which is low for edible oils, and that too when it is stored at a temperature in the range of 10 to 22 degrees celsius.
