Squalene vs Squalane: Understanding the Key Differences

When it comes to skincare ingredients, the conversation often revolves around the benefits and uses of various compounds. Two such ingredients that frequently come up are squalene and squalane. While they may sound similar and are related in nature, their differences are significant in terms of stability, source, and use in skincare products. This article will delve into the key distinctions between squalene and squalane, providing valuable insights into their unique properties and applications.

What is Squalene?

Squalene is a naturally occurring lipid produced by all plants, animals, and humans. It is a polyunsaturated hydrocarbon that plays a crucial role in the synthesis of cholesterol, steroid hormones, and vitamin D in the human body. In skincare, squalene is valued for its moisturizing properties and its ability to help maintain a healthy skin barrier.

• Source: Squalene is most commonly derived from shark liver oil, but due to ethical and sustainability concerns, plant-based sources like olives, amaranth seeds, rice bran, and wheat germ are now more prevalent.
• Properties: It is an unsaturated oil, which makes it highly susceptible to oxidation when exposed to air and light. This can lead to a shorter shelf life and potential skin irritation if oxidized squalene is applied to the skin.

What is Squalane?

Squalane is the hydrogenated version of squalene. This means that it is a saturated compound, which makes it much more stable and less prone to oxidation. Squalane retains the beneficial properties of squalene but is more suitable for use in skincare formulations due to its longer shelf life and non-irritating nature.

• Source: Like squalene, squalane can be derived from shark liver or plant sources. However, the cosmetic industry predominantly uses 100% plant-derived squalane to avoid overfishing and to cater to vegan and cruelty-free product demands.
• Properties: Squalane is a lightweight, non-comedogenic oil that is suitable for all skin types. It is an excellent emollient, providing hydration without leaving a greasy residue.

Comparing Squalene and Squalane

Understanding the differences between squalene and squalane is essential for making informed choices about skincare products. Here are the key distinctions:

Stability and Oxidation

Squalene’s unsaturated nature makes it prone to oxidation, which can lead to rancidity and reduced efficacy. On the other hand, squalane is stable and resistant to oxidation, making it a more reliable ingredient in skincare formulations.

Moisturizing Effects

Both squalene and squalane are excellent moisturizers, but squalane’s stability means it can deliver consistent hydration over time without the risk of oxidation that could potentially irritate the skin.

Skin Absorption

Squalane has a lighter texture and is more easily absorbed by the skin compared to squalene. This makes squalane a preferred choice for leave-on skincare products.

Sustainability and Ethical Considerations

The shift towards plant-derived squalane addresses the environmental and ethical concerns associated with harvesting squalene from shark liver. Consumers are increasingly seeking out sustainable and cruelty-free skincare options.

Applications in Skincare

Both squalene and squalane have their place in skincare, but squalane’s advantages make it more common in a variety of products:

• Moisturizers: Squalane is a staple in face creams and body lotions due to its hydrating and non-greasy properties.
• Serums: Its fast absorption makes squalane an ideal ingredient in facial serums, where it helps to lock in moisture and restore skin’s suppleness.
• Lip Treatments: Squalane’s emollient qualities are beneficial in lip balms and treatments, providing long-lasting hydration and protection.
• Foundations and Primers: Squalane is often included in makeup products for its ability to create a smooth, hydrated canvas without clogging pores.

Choosing the Right Ingredient for Your Skin

When selecting skincare products, consider your skin type and concerns. If you have oily or acne-prone skin, squalane’s lightweight and non-comedogenic nature might be more suitable. For those with dry or mature skin, squalane’s hydrating and anti-aging benefits can be particularly advantageous.

Conclusion: Embracing Plant-Derived Squalane

In conclusion, while squalene and squalane share similar moisturizing properties, squalane’s stability, skin-friendliness, and ethical sourcing make it the superior choice for skincare formulations. As consumers become more conscious of the ingredients in their products, the demand for plant-derived squalane is likely to continue rising.
