The Hidden Treasure Nature Offers Our Skin: Hazelnut Oil
In the modern world of cosmetics, the power of traditional methods and natural ingredients is being understood more and more every day. Among these natural ingredients, Corylus avellana seed oil (hazelnut oil), obtained from the hazelnut—which is abundant in Anatolian lands and known for its nutritional value—has earned an indispensable place in skincare routines. As Tanura, we aim to offer the gentlest touch to your skin by combining this pure energy of nature with our professional formulations. In this article, we will examine in detail the importance of hazelnut oil in the cosmetic world, its rich components, and its positive effects on your skin.
What is Corylus Avellana (Hazelnut Oil)?
The hazelnut tree, known by its scientific name Corylus avellana, is a plant that belongs to the birch family (Betulaceae) and thrives in temperate climates. Hazelnut oil used in the cosmetic industry is obtained by pressing hazelnut kernels using the cold press method. The cold press method is considered the highest quality production form because it prevents the vitamins, minerals, and essential fatty acids within the oil from degrading due to exposure to heat.
Hazelnut oil is, by nature, a very light, fluid oil that penetrates the skin quickly. Its color can range from pale yellow to golden yellow, and it has a characteristic, mild nutty scent. Looking at its chemical profile, it is seen to contain a high percentage of oleic acid (Omega-9), linoleic acid (Omega-6), vitamin E (tocopherol), phytosterols, and various minerals (magnesium, potassium, calcium). This rich content makes it not just a moisturizer, but also a versatile skincare active.
Its Cosmetic Role in Skincare
Hazelnut oil is frequently preferred in cosmetic formulations as a "carrier oil" or "active ingredient." Its effects on the skin stem from the synergy of the fatty acids and antioxidants it contains. Here are the prominent cosmetic benefits of hazelnut oil:
1. Deep Moisturization and Softening
Hazelnut oil has excellent emollient properties. It creates a natural barrier that helps prevent moisture loss on the skin's surface. Thanks to the high oleic acid content, it penetrates into the lower layers of the skin, supporting a more supple, soft, and smooth appearance.
2. Natural Astringent Effect
One of the most important features that distinguishes hazelnut oil from other vegetable oils is that it is a natural astringent. Thanks to this property, it helps to minimize the appearance of pores on the skin and helps refine the skin texture. The fact that it provides pore care without weighing down the skin or leaving a greasy feeling makes it unique in cosmetics.
3. Antioxidant Protection
Its rich vitamin E content makes hazelnut oil a powerful source of antioxidants. Antioxidants help protect the skin against external factors (air pollution, oxidative stress caused by UV rays, etc.). This protection supports the skin in exhibiting a more vibrant, bright, and youthful appearance.
4. Supporting the Skin Barrier
Essential fatty acids are critical for maintaining the integrity of the skin barrier. Hazelnut oil contributes to the formation of a more resistant skin structure against external stimuli by strengthening the skin's lipid barrier. This is of great importance, especially for the revitalization of dehydrated and dull skin.
Which Skin Types Is It Suitable For?
Hazelnut oil has a structure close to the "dry oil" category; meaning it is absorbed quickly by the skin and does not leave a sticky layer. Thanks to this feature, it appeals to a wide range of skin types:
- Oily and Combination Skin: Thanks to its light structure and astringent effect, it helps maintain sebum balance without clogging pores.
- Dry Skin: With its high fatty acid content, it provides the intense moisture that dry skin needs and reduces the appearance of flakiness.
- Sensitive Skin: It offers gentle care that supports the sensitive skin structure with its natural and soothing properties.
- Mature Skin: With its antioxidant capacity, it helps improve the overall appearance of the skin against signs of aging.
How Is It Used in Cosmetic Products?
Hazelnut oil can appear in different forms within cosmetic products. This valuable ingredient, which we frequently include in Tanura products, can be used in the following ways:
- Facial Care Oils and Serums: It can be used alone or mixed with other vegetable oils (rosehip, jojoba, etc.) in night or day care.
- Moisturizing Creams: It is included in the content of daily moisturizers to increase the moisture-retention capacity of the product.
- Cleansing Oils: It is preferred in oil-based cleansers to gently dissolve makeup and dirt on the skin.
- Body Lotions: It is used to maintain moisture balance all over the body and to provide a silky touch to the skin.
Things to Consider
Although hazelnut oil is a natural and safe ingredient, there are some points to consider when using it:
- Allergy Risk: Since hazelnuts are a tree nut, individuals with a hazelnut allergy should definitely consult a specialist before using cosmetic products containing this oil.
- Patch Test: Before applying any cosmetic product to your entire face, it is recommended to test it on a small area on the inside of your wrist to observe your skin's reaction.
- Storage Conditions: Natural oils can be affected by light and heat. You can extend the life of your products by storing them in a cool, dark, and dry place.
Conclusion
Corylus avellana seed oil, or hazelnut oil, is one of the most valuable cosmetic ingredients nature offers us, as it moisturizes the skin, regulates the appearance of pores, and provides antioxidant protection. Thanks to its light structure and rapid absorption, this ingredient, which adapts to every skin type, creates a noticeable vitality on your skin when combined with Tanura's professional care approach.
