Have you ever read the label of a moisturizer or facial serum and come across two mysterious ingredients: Squalane e SqualaneYou may have wondered what the differences are between squalane and squalene and why they appear so often in natural beauty products. Both are oily substances, but they perform different functions and have unique characteristics. In this article, Nuvole di BellezzaWe'll delve into the world of these two much-talked-about ingredients, revealing their properties, their skin benefits, and which cosmetic products are most likely to contain them.
Why are Squalane and Squalene so loved?
Squalane (or Squalane) and Squalene are substances that are gaining more and more popularity in the world of cosmetics thanks to their beneficial properties for the skin. But why do we hear so much about them?
- Natural origin: Both Squalane and Squalene are derived from natural sources, making them cosmetic ingredients biocompatible and well tolerated by most people.
- Emollient and hydrating properties: Both help keep skin soft, supple and hydrated.
- Protective action: They can help strengthen the skin barrier by protecting it from external factors such as smog, wind and UV rays.
However, despite the similarities, Squalane and Squalene do have some substantial differences that are important to know to choose the right product for your skincare routine. Read on to find out everything you need to know about these two beauty allies!
What is Squalene?
Squalene is a natural compound found in human skin and in various animal and plant sources, such as olive oil and shark liver (yes, unfortunately you read that right but continue reading to learn more). It is an oily substance that keeps the top layer of the epidermis hydrated, preventing water evaporation. Thanks to its ability to mimic the skin's lipids, squalene helps keep the skin soft and hydrated.

What is Squalane?
Squalane is a hydrogenated version of squalene, obtained through a process that makes the molecule more stable and resistant to oxidation. This chemical transformation is necessary because squalene is very unstable and oxidizes easily when in contact with air. Squalane, on the other hand, maintains the same hydrating properties as squalene, but with a longer shelf life of the product.
Difference Between Squalane and Squalene
The difference between squalane and squalene lies in the stability of the molecule. While squalene is very unstable and oxidizes quickly, squalane is a stable substitute for squalene. This makes squalane more suitable for use in cosmetic products, as it can last longer without deteriorating.
Let's get to know Squalene better: origin, properties and benefits for the skin
Definition and Origin of Squalene
Squalene is a natural component of our skin and can be derived from animal and plant sources. When squalene is produced synthetically or extracted from plant sources, such as olive oil, it becomes a key ingredient in natural and organic cosmetics. Squalene is similar to skin lipids, making it an effective ingredient for maintaining skin health.

Properties of Squalene
- Moisturizing: Squalene is an excellent emollient moisturizer, able to penetrate the deep layers of the skin and retain water, keeping it soft and elastic.
- Emollient: It gives the skin a feeling of softness and smoothness, counteracting dryness and dehydration.
- Protective: It helps strengthen the skin barrier, protecting the skin from external agents such as smog, wind and UV rays.
- Antioxidant: Some research suggests that squalene may have antioxidant properties, counteracting the action of free radicals responsible for skin aging.
How Squalene Works on the Skin
Squalene exerts its beneficial action on the skin thanks to its unique chemical structure. Its affinity with human sebum makes it easily absorbed by the skin, where it acts as a true "natural oil". Penetrating into the deep layers, Squalene helps restore the skin's hydrolipidic balance, keeping it hydrated, soft and protected. In addition, its emollient property helps reduce flaking and combat skin dryness.
Limitations of Squalene
Despite its many benefits, Squalene has some limitations that hinder its use in cosmetics:
- Instability: Squalene is a chemically unstable compound and tends to oxidize easily upon contact with air and light, losing its beneficial properties and taking on a yellowish color.
- Comedogenicity: Some research suggests that Squalene may be comedogenic, meaning it may clog pores and cause blackheads and pimples. However, this is controversial and depends on several factors, such as skin type and product formulation.
Why is Squalene not always present in finished cosmetics?
Due to its instability and potential comedogenicity, Squalene is not always present in finished cosmetics. To overcome these problems, the cosmetic industry has developed a derivative of Squalene: Squalane.
Squalane: the stable derivative of Squalene
Definition and Production of Squalane
Squalane is a saturated aliphatic hydrocarbon, obtained through a hydrogenation process of Squalene. This process eliminates the double bonds of the Squalene molecule, making it more stable and resistant to oxidation.
Origin of Squalane
Vegetable squalane is obtained mainly from sources such asolive oil, rice bran and sugar cane. This choice makes squalane a sustainable and cruelty-free solution, unlike squalene extracted from shark livers. Using plant-based products is not only ethically correct, but also guarantees a more stable supply and less impact on the environment.
Properties of Squalane
- Emollient: Squalane retains the emollient properties of Squalene, giving the skin softness and smoothness.
- Moisturizing: Squalane also has a hydrating action, helping to keep the skin elastic and hydrated.
- Non-comedogenic: Unlike Squalene, Squalane is generally considered non-comedogenic, meaning it will not clog pores.
- Stable: Squalane is a chemically stable compound and resists oxidation, maintaining its beneficial properties over time.
Benefits of Squalane for the Skin
What are its benefits? Squalane is known for its moisturizing and protective properties. Some research also attributes squalene to a protective action against pathogens, thanks to the maintenance of a healthy skin barrier. Squalane is used in skin care products to prevent dryness, improve elasticity, and reduce the skin's susceptibility to skin disorders and skin cancer.
- Elasticity and softness: Squalane helps keep skin elastic and soft, counteracting dryness and dehydration.
- Protection: It helps strengthen the skin barrier, protecting the skin from external agents such as smog, wind and UV rays.
- Soothing: Squalane has soothing and calming properties, making it suitable for sensitive and irritated skin.
- Antioxidant: Some research suggests that squalane may have antioxidant properties, counteracting the action of free radicals responsible for skin aging.
Squalane in cosmetic products
Squalane has become a popular ingredient in cosmetics because of its ability to moisturize and protect the skin without clogging pores. Many skin care products, including serums, creams, and oils, contain squalane to improve skin hydration and texture. Because of its similarity to the skin's natural lipids, squalane is ideal for all skin types, including sensitive skin and baby skin.
Main Difference Between Squalane and Squalene: Oxidation Stability
The main difference between Squalane and Squalene lies in their stability to oxidation. Squalene, as we have seen, is an unstable compound that tends to oxidize easily upon contact with air and light, losing its beneficial properties and taking on a yellowish color. Squalane, on the other hand, thanks to the hydrogenation process, becomes a chemically stable compound that is resistant to oxidation, maintaining its beneficial properties over time.
