Squalane vs Squalene: What Is the Difference and Which Should You Use?

Squalane vs Squalene: What Is the Difference and Which Should You Use?

If you have ever spent more than five minutes browsing the aisles of a skincare shop or scrolled through DIY beauty forums, you have likely encountered the terms squalane and squalene. At first glance, they look like a simple typo, but in the world of cosmetic chemistry, that one-letter difference is everything. Understanding the squalane vs squalene difference skincare enthusiasts often ask about is the first step toward creating professional-grade products that truly perform on the skin. Whether you are a seasoned home formulator or a beginner looking to mix your first facial oil, knowing which one to reach for can mean the difference between a shelf-stable masterpiece and a serum that goes rancid before you can finish the bottle. In the Australian climate, where the sun can be harsh and the air dry, having a reliable emollient in your toolkit is not just a luxury—it is a necessity for maintaining a healthy skin barrier. Both of these ingredients are famous for their ability to soften the skin and lock in moisture, but they are far from interchangeable. As we delve into the details, you will see why the transition from the “e” to the “a” version was such a significant breakthrough for the beauty industry and for home formulators alike. This single change in chemical structure solved one of the biggest problems in natural skincare: how to provide the benefits of our skin’s natural oils without the drawbacks of rapid oxidation and potential irritation.

In this comprehensive guide, we are going to dive deep into the science behind these two powerhouse lipids. We will explore why our skin naturally produces one, why the skincare industry prefers the other, and how you can use them in your own DIY creations. We will also discuss the ethical implications of sourcing these ingredients and how to ensure you are using the highest quality, plant-derived versions available. By the end of this article, you will not only understand the squalane vs squalene difference skincare experts rave about, but you will also have a practical recipe to start incorporating these “liquid gold” ingredients into your daily routine. Let’s demystify these ingredients and help you choose the best one for your unique skin type, whether you are dealing with dryness, oiliness, or signs of ageing. Whether you are looking to simplify your routine or build a complex, multi-step regimen, squalane is an ingredient that deserves a permanent spot on your vanity. It represents the perfect marriage of nature and science, taking a naturally occurring substance and making it even better for topical use. This balanced approach to skincare ensures that you are getting the best of both worlds: the power of nature and the stability of modern science.

What Is Squalene?

To understand the difference, we first need to look at the original molecule: Squalene (with an “e”). Squalene is a natural polyunsaturated lipid that is produced by our own bodies. In fact, it makes up about 10% to 13% of our skin’s sebum—the natural oils our skin produces to stay hydrated and protected. It is a vital part of our skin’s chemistry, acting as a natural moisturiser and a “sacrificial” antioxidant that protects our skin cells from oxidative damage caused by UV rays and environmental pollutants. This makes it a key player in reducing oxidative stress and maintaining healthy skin. Our bodies produce the most squalene in our teenage years, but this production begins to decline significantly once we hit our 20s and 30s, which is one of the reasons why our skin can start to feel drier and less resilient as we age. By understanding how squalene works, we can better appreciate why replacing it topically is so beneficial for mature or dry skin types. It’s essentially our body’s own built-in protective layer, but one that unfortunately doesn’t stay at peak levels forever.

Historically, squalene was famously discovered in 1906 by Dr Mitsumaro Tsujimoto, who isolated it from shark liver oil. This is where the name comes from—the Squalidae family of sharks. For many years, sharks were the primary source of squalene for the cosmetic industry, which raised significant ethical and environmental concerns. However, for the modern, ethical DIYer, there is good news: squalene is also found abundantly in plants. High concentrations can be found in olive oil, rice bran, amaranth seeds, and even sugar cane. While it is an incredible ingredient for the skin, squalene has one major drawback for home formulators: it is highly unstable. Because it contains multiple double bonds in its chemical structure, it oxidises very quickly when exposed to air. When squalene oxidises, it can actually become comedogenic (pore-clogging) and may contribute to acne breakouts, which is why you rarely see pure squalene in commercial skincare products today. This instability is the primary reason why the “a” version was developed. The process of oxidation doesn’t just make the oil smell bad; it fundamentally changes its chemical properties, turning a beneficial lipid into a potential irritant.

What Is Squalane?

This brings us to Squalane (with an “a”). Squalane is the hydrogenated version of squalene. Through a process called hydrogenation—the same process used to turn vegetable oil into a more stable form—the unstable double bonds in squalene are saturated with hydrogen. This chemical “makeover” transforms the oil into a completely stable, shelf-hardy saturated fat that does not oxidise or go rancid easily. It is a clear, odourless, and highly stable compound with excellent resistance to heat and oxidation. This means that unlike squalene, squalane can be stored for long periods without losing its efficacy or becoming harmful to the skin. This stability is what makes it such a darling of the cosmetic industry. It can be shipped around the world, stored in warehouses, and sit on a retail shelf for months without any degradation in quality. For the home formulator, this means you don’t have to worry about your expensive ingredients going to waste before you can use them all.

The squalane vs squalene difference skincare benefit here is primarily stability. Squalane retains almost all the skin-loving properties of squalene—it is still an exceptional emollient, it is highly biocompatible, and it feels incredibly silky on the skin—but it can sit on your bathroom shelf for two years without losing its potency. Squalane mimics our skin’s natural oils so closely that it absorbs almost instantly without leaving a greasy residue. For DIY skincare enthusiasts, squalane is the gold standard because it is easy to work with, safe for all skin types, and provides a professional sensory feel to any handmade product. It is often referred to as an “oil-less” oil because of its unique texture and rapid absorption rate. When you apply squalane, it doesn’t just sit on top of the skin like a heavy mineral oil; it actually integrates into the skin’s lipid barrier, helping to repair and strengthen it from within. This makes it particularly effective for those with sensitive skin or conditions like rosacea, where the skin barrier is often compromised. It provides a soothing, protective layer that helps to keep environmental triggers at bay while allowing the skin to heal and regenerate naturally. This biocompatibility is why it rarely causes reactions; the skin essentially “recognises” it as its own.

Benefits of Squalane for Skin

When discussing the squalane vs squalene difference skincare benefits, most of the praise goes to squalane for its versatility. Here are the top reasons why you should include it in your formulations:

• Deep Hydration without Greasiness: Squalane is an “oil-less” oil. It provides intense moisture and helps prevent water loss by sealing moisture into the skin, yet it feels weightless and sinks in faster than traditional carrier oils like jojoba or almond oil. This makes it ideal for layering under makeup or other skincare products, as it won’t cause them to slide or pill. It is the perfect solution for those who hate the feeling of heavy oils but desperately need the hydration they provide. Its unique molecular weight allows it to penetrate the upper layers of the skin quickly, providing immediate relief from dryness without the shiny, oily look that many other emollients produce.
• Non-Comedogenic and Acne-Friendly: Unlike many other oils, squalane has a very low comedogenic rating. Because it is stable and doesn’t oxidise on the skin, it is less likely to clog pores or trigger inflammation, making it a safe choice even for those with oily or acne-prone skin. It helps to balance sebum production by providing the skin with the lipids it needs, which can actually reduce overall oiliness over time. By mimicking the skin’s natural oils, it “tricks” the skin into producing less sebum, leading to a clearer, more balanced complexion. This is a crucial point for those who have been told to avoid oils entirely; squalane is the exception that can actually help your skin find its balance.
• Soothes Irritation and Redness: Squalane has natural anti-inflammatory properties. It is excellent for calming skin conditions like eczema, psoriasis, or general sensitivity, helping to repair the skin barrier and reduce redness. It acts as a protective shield, keeping irritants out while locking moisture in, which is crucial for those with compromised skin barriers. Its gentle nature means it can be used even on the most delicate skin, including the area around the eyes, without causing irritation or puffiness. Many users find it significantly reduces the “tight” feeling associated with dry or irritated skin, providing a sense of comfort that lasts throughout the day.
• Anti-Ageing Support: As we age, our natural production of squalene drops significantly. Applying squalane topically helps replenish these lost lipids, improving skin elasticity and reducing the appearance of fine lines and wrinkles. It gives the skin a more youthful, plump appearance by filling in the gaps between skin cells. Regular use can help to firm the skin and improve its overall texture, making it look smoother and more radiant. It also helps to protect against the damaging effects of UV radiation and pollution, which are major contributors to premature ageing. By strengthening the skin barrier, it helps the skin remain resilient against the environmental stressors that accelerate the ageing process.
• Enhances Ingredient Absorption: Squalane acts as an excellent “carrier.” Because its molecular structure is so similar to our skin’s sebum, it can help other active ingredients in your DIY serums penetrate deeper into the skin’s layers. This increases the overall effectiveness of your skincare routine, making your other expensive ingredients work even harder. Whether you are using it with Vitamin C, Retinol, or Hyaluronic Acid, squalane helps these actives reach their target more efficiently, ensuring you get the maximum benefit from every drop of your handmade products. This makes it an invaluable addition to any multi-ingredient formulation where performance is a priority.

What You Need

Creating your own squalane-based facial oil is one of the easiest DIY projects for beginners. It requires minimal equipment and results in a high-end product that rivals expensive store-bought serums. To make our signature “Liquid Gold” facial oil, you will need the following ingredients and tools:

• 30ml Plant-derived Squalane Oil (look for olive or sugar cane derived)
• 15ml Jojoba Oil (technically a liquid wax that mimics sebum and adds vitamins)
• 5ml Rosehip Oil (packed with Vitamin A and essential fatty acids for regeneration)
• 2 drops Vitamin E Oil (acts as a powerful antioxidant for the rosehip oil)
• A 50ml amber glass dropper bottle (to protect the oils from light)
• A small stainless steel or glass funnel (to prevent spills)
• Isopropyl alcohol (for sanitising your tools and workspace)

Step-by-Step Recipe: The “Liquid Gold” Facial Oil

1. Sanitise Your Equipment: Hygiene is the most important part of DIY skincare. Spray your dropper bottle, funnel, and any measuring tools with isopropyl alcohol and let them air dry completely before starting. This prevents bacteria and mould from contaminating your oil and ensures a longer shelf life. Even though this is an anhydrous (water-free) product and doesn’t strictly require a preservative, starting with clean tools is a non-negotiable step for any responsible formulator. Taking this extra minute now can save you from having to throw away a contaminated batch later.
2. Measure the Squalane: Using your funnel, pour 30ml of plant-derived squalane oil into your glass bottle. This forms the lightweight, fast-absorbing base of your serum and provides the primary hydration. You can use a small measuring cylinder if you want to be precise, or simply estimate based on the bottle size. Squalane is the star of the show here, providing that signature silky feel that makes this serum so enjoyable to use. It’s the ingredient that will make your skin feel instantly smoother and more hydrated.
3. Add Your Carrier Oils: Carefully add the 15ml of jojoba oil and 5ml of rosehip oil to the bottle. The jojoba oil adds a bit more body to the serum and provides a boost of Vitamin E and B-complex vitamins, while the rosehip oil provides that beautiful golden colour and a boost of skin-regenerating nutrients like Vitamin A and essential fatty acids. Watch as the colours swirl together—it’s quite a satisfying process that highlights the natural beauty of these botanical ingredients. Each oil brings its own unique set of benefits, creating a well-rounded serum that addresses multiple skin concerns at once.
4. Fortify with Vitamin E: Add 2 drops of Vitamin E oil. While squalane itself is very stable, rosehip oil is quite delicate and prone to oxidation. The Vitamin E helps to extend the shelf life of the rosehip oil in your blend, ensuring your serum stays fresh for as long as possible. It also provides an extra layer of antioxidant protection for your skin, helping to fight off free radicals throughout the day. This small addition is crucial for maintaining the potency of the more fragile oils in your recipe.
5. Mix and Label: Secure the dropper lid tightly and give the bottle a gentle shake to combine the oils. Don’t forget to label your bottle with the product name and the date you made it. Your “Liquid Gold” facial oil is now ready to use! Store it in a cool, dark place to keep it at its best. Proper labeling is a key habit for any DIYer, as it helps you keep track of your creations and ensures you use them while they are at their most potent. It also makes your homemade products look and feel more professional.

Tips for Best Results

To get the most out of the squalane vs squalene difference skincare advantages and your new DIY creation, follow these professional tips from a formulator’s perspective:

• Apply to Damp Skin: Squalane is an emollient, meaning it works best when it can seal in existing moisture. For the ultimate glow, apply 2-3 drops of your facial oil immediately after washing your face or applying a water-based toner, while your skin is still slightly damp. This “traps” the water in your skin for superior hydration and ensures the oil spreads easily and evenly across your face. You’ll find that you need less product when applying to damp skin, making your handmade serum last even longer.
• Customise for Your Skin Type: The beauty of DIY is the ability to tweak recipes. If you have very dry skin, you can increase the rosehip oil to 10ml and decrease the squalane. If you have very oily skin, you can use 100% squalane as a standalone moisturiser—it works wonders for balancing oily patches without feeling heavy. You can also experiment with other carrier oils like argan or marula oil to further tailor the serum to your skin’s specific needs.
• Use it on Hair and Nails: Squalane isn’t just for your face! A few drops on the ends of damp hair can prevent split ends and add shine without weighing it down. You can also rub a drop into your cuticles every night to keep them soft and healthy, especially during the dry Australian summer or cold winter months. It’s also a great lightweight body oil for areas like the elbows and knees that tend to get extra dry.
• Layer Correctly: In a multi-step routine, always apply your water-based products (like hyaluronic acid or vitamin C serums) first, followed by your squalane oil, and then your heavier cream or sunscreen. This ensures that each product can penetrate the skin effectively and do its job. Think of your skincare routine like a series of layers, moving from the thinnest, most watery products to the thickest, most occlusive ones.

Safety and Patch Testing

While squalane is considered one of the safest and most non-irritating ingredients in skincare, everyone’s skin chemistry is unique. Before applying your new DIY serum to your entire face, it is essential to perform a patch test. Apply a small amount of the oil to the inside of your wrist or behind your ear and wait 24 hours. If you notice any redness, itching, or irritation, discontinue use immediately. Additionally, if you have a known allergy to olives or the specific plants your oils are derived from, consult with a dermatologist before use. Always store your finished products in a cool, dark place away from direct sunlight to maintain the integrity of the ingredients and prevent premature oxidation of the carrier oils. Using amber glass bottles is a great way to provide an extra layer of protection for your handmade creations. Always remember that even natural ingredients can cause reactions in some individuals, so being cautious is part of being a responsible home formulator. This practice is key to maintaining healthy skin while exploring the world of DIY beauty. This cautious approach ensures that your journey into handmade cosmetics remains a positive and skin-friendly experience.

Frequently Asked Questions

Q: Is squalane better than squalene?
A: From a practical skincare and formulation standpoint, yes. While squalene is a fantastic natural antioxidant produced by our bodies, it is simply too unstable for bottled products. Squalane provides almost identical skin benefits—hydration, softening, and protection—but with a shelf life that makes it much more reliable for home formulators and commercial brands alike. It gives you all the benefits without the risk of oxidation. In essence, squalane is the “skincare-ready” version of what our bodies naturally produce, offering all the pros with none of the cons. It allows us to replenish what time and environment take away, but in a way that is safe and effective for topical application.

Q: Is all squalane vegan and cruelty-free?
A: Not automatically, but the vast majority of squalane used today is. Historically, squalene was sourced from shark livers, which is neither vegan nor sustainable. Today, most high-quality squalane is derived from plant sources like olives, sugar cane, or amaranth. When purchasing your ingredients, always look for “plant-derived” or “vegan” certifications to ensure your DIY products align with your ethical values. Choosing plant-based squalane is a simple way to make your beauty routine more compassionate and environmentally friendly.

Q: Can I use squalane if I have oily or acne-prone skin?
A: Absolutely! In fact, squalane is one of the best oils for oily skin. Because it mimics our skin’s natural sebum so closely, it can help regulate oil production. Often, oily skin is actually dehydrated skin trying to compensate; by providing a lightweight, non-comedogenic source of moisture like squalane, you can help your skin reach a healthier balance without causing breakouts or leaving a greasy film. It’s a great way to hydrate without the fear of clogging your pores. Many people find that their skin actually clears up once they start using squalane consistently.
