If you’re anything like me, reading an ingredient list on skincare products can feel like trying to decode a science textbook. Words like “squalene” and “squalane” might look similar, but they’re two very different ingredients with unique benefits for the skin. Understanding what sets them apart and why they’re used can make a world of difference when choosing products that work.
Both squalene and squalane are powerhouse ingredients in skincare—hydrating, gentle, and incredibly effective. But which one does what, and why should you care? Let’s find out.
What is Squalene?
Squalene (with an “e”) is a naturally occurring lipid. It’s produced by our sebaceous glands and is a key part of our skin’s natural moisture barrier. In fact, it makes up about 10-12% of the skin’s sebum. This lipid helps keep skin soft, smooth, and hydrated while protecting against environmental damage.
Unfortunately, as we age, our natural production of squalene starts to decline. By the time you hit your 30s, those levels can drop dramatically, leaving your skin drier and more vulnerable to fine lines, rough patches, and irritation. This is where squalene as a skincare ingredient comes into play.
Traditionally, squalene was derived from shark liver oil, which was a highly controversial practice. Thankfully today, most squalene used in modern skincare comes from plant-based sources like olives, rice bran, and sugarcane.
The Problem with Pure Squalene
While squalene sounds amazing, it has a major drawback for skincare formulators and that is it’s highly unstable. When exposed to air, squalene oxidizes quickly, losing its effectiveness and even risking irritation for sensitive skin. For this reason, you’re unlikely to see pure squalene in most skincare products. Instead, chemists discovered a way to stabilize it—and that’s where squalane enters the picture.
What is Squalane?
Squalane (with an “a”) is the hydrogenated, more stable version of squalene. By adding hydrogen atoms to squalene’s molecular structure, it becomes fully saturated and far more resistant to oxidation. In simple terms, squalane keeps all the hydrating and soothing benefits of squalene but with added shelf life and zero risk of irritation.
This stabilized form of squalene has quickly become a skincare superstar. Lightweight and non-comedogenic, squalane sinks effortlessly into the skin without clogging pores, making it a favorite for all skin types—even oily and acne-prone complexions.
How Squalane Benefits Your Skin
Squalane’s magic lies in its versatility and compatibility with the skin. Because it mimics your natural oils, it works seamlessly to restore moisture, strengthen the skin barrier, and deliver a healthy glow. Here are a few key benefits:
- Deep Hydration – Squalane penetrates deep into the skin to deliver long-lasting hydration without feeling greasy or heavy.
- Non-Irritating – Unlike some heavier oils, squalane is gentle and non-irritating, making it perfect for sensitive skin.
- Improved Skin Barrier – By replenishing lipids, squalane supports a healthy barrier function, helping the skin retain moisture and fend off environmental stressors.
- Anti-Aging Properties – Hydrated skin naturally looks plumper and smoother, reducing the appearance of fine lines and wrinkles.
- Balancing Oil Production – For those with oily or acne-prone skin, squalane can help regulate oil production by giving your skin the moisture it needs.
Squalane in Skincare Products
Squalane is a popular ingredient in a variety of skincare products, including serums, moisturizers, and facial oils. Its lightweight nature makes it a versatile addition to almost any formula, whether you’re looking to hydrate, soothe, or balance your skin.
For example:
- Squalane Serums – These are perfect for delivering a concentrated boost of hydration without feeling heavy.
- Moisturizers – Adding squalane to a cream or lotion helps lock in moisture while providing a smooth, silky finish.
- Facial Oils – Pure squalane oil can be used as the final step in your skincare routine to seal in all the benefits of your serums and moisturizers.
And the best part? Squalane plays well with other ingredients. Whether it’s paired with hyaluronic acid for extra hydration, niacinamide for brightening, or antioxidants for protection, squalane enhances the performance of many popular skincare actives.
Is Squalane Better Than Squalene?
At this point, it’s clear that squalane is the superior option for skincare. While squalene is beneficial in its natural form, its instability makes it impractical for use in products. Squalane, on the other hand, delivers all the same benefits in a more stable, effective, and skin-friendly form.
If you’re scanning a product label and see squalane, you can feel confident knowing you’re getting an ingredient that’s been optimized for your skin.
A Plant-Based Future for Squalane
As demand for ethical and sustainable skincare grows, plant-derived squalane has taken center stage. Today, most squalane comes from renewable sources like olives, sugarcane, and other plants. Not only is this better for the environment, but it also ensures that the squalane used in your products is pure, high-quality, and cruelty-free.
While squalene and squalane might look nearly identical on paper, squalane is the real hero in skincare. Stable, versatile, and deeply nourishing, it offers a simple yet powerful way to boost hydration, strengthen your skin barrier, and maintain a healthy glow.
