Squalene or Squalane? What They Are & How to Use Them in Skincare

10 minute read

Before serums and skincare routines, before product shelves and actives, your skin already had a built-in support system.

It made its own moisturiser. It protected itself.

And at the heart of that protection was a little-known lipid called squalene.

We often see its name in ingredient lists, sometimes as squalene, sometimes as squalane. But what is it really? Why is it special? Why does it show up in the most luxurious facial oils and the gentlest baby balms?

This guide walks you step by step through the story, science, and practical uses of squalene. Whether you're a formulator or a skincare lover, you'll walk away understanding not just how to use it but also why it’s worth using.

Here’s What You’ll Learn

What is Squalene?

Squalene is a natural lipid. It’s a light, oil-like substance that your body produces. It makes up around 12 to 13 percent of your skin’s sebum, the oily layer secreted by sebaceous glands.

This makes it biocompatible, meaning your skin recognises it as its own. It absorbs easily, feels smooth and non-greasy, and plays a vital role in helping your skin:

  • Stay hydrated and supple

  • Maintain a healthy upper skin layer

  • Protect against environmental stressors

  • Reduce moisture loss (TEWL)

However, like many natural compounds, squalene production declines with age, especially after 30. That’s when dryness, dullness, and sensitivity often begin.

By applying it topically, we’re simply supporting what the skin no longer produces in abundance.

Why Is Squalene So Special?

Why Is Squalene So Special

Imagine your skin barrier like a brick wall. The skin cells are the bricks, and lipids act as the mortar. Squalene is one of those lipids, sitting alongside ceramides, cholesterol, and fatty acids.

It plays a quiet but important role in:

  • Sealing in moisture

  • Softening the skin’s texture

  • Defending against oxidative stress from UV exposure, pollution, and inflammation

Unlike many oils, squalene doesn’t clog pores, irritate the skin, or feel heavy. It works with your skin, not against it, making it suitable for nearly all skin types.

 

The Origins: From Shark Livers to Olive Groves

Sources of Squalane

Squalene was first discovered in shark liver oil, especially from deep-sea sharks that rely on it for buoyancy and survival in extreme conditions.

In fact, the name comes from the Latin word “Squalus,” meaning shark.

But this harvesting method proved both unsustainable and unethical. Fortunately, researchers discovered that plants, particularly olives, also contain squalene in significant amounts.

Today, olive-derived squalene is the industry standard for clean and ethical beauty. It offers:

  • A vegan, cruelty-free alternative

  • A sustainable by-product of olive oil refining

  • Identical benefits to shark-derived squalene

Is olive-derived squalene the same as shark-derived?
Yes. They are chemically identical, but olive-derived squalene is sustainably sourced and plant-based.

How Olive Squalene Is Extracted

Olive squalene is extracted during the refining process of olive oil. The process is as follows:

  1. Olives are harvested and cold-pressed to extract oil

  2. During refining, the unsaponifiable fraction (about 0.7 to 1 percent) is separated

  3. Squalene is isolated and purified from this fraction

  4. It can optionally be hydrogenated to produce squalane, the more stable form

Is Olive Squalane natural or synthetic?

It is naturally derived. The hydrogenation process simply increases stability for skincare use. It remains plant-based and non-toxic.

Squalene vs. Squalane: What’s the Difference?

Squalene and squalane are often confused, but they serve very different purposes in formulation.

Squalene is the raw, unsaturated form of this lipid, naturally found in the skin’s sebum. While it is bioactive and quickly absorbed, it oxidises easily. This shortens its shelf life and can make it unstable in finished products.

Squalane, however, is the hydrogenated, saturated version. This process makes it more stable and less reactive, increasing its shelf life and allowing it to perform consistently across different formulations.

Although the raw form may appear more natural, squalane is the safer and more effective option for modern skincare. It delivers all the skin compatibility benefits of squalene without the instability.

That’s why at Craft 360, we offer high-purity Olive Squalane, a plant-derived lipid designed specifically for formulators who prioritise stability, compatibility, and performance.

A Formulator’s Guide to Using Squalane

Squalane is suitable for a wide range of product types. Here's how to use it effectively in your formulations.

Best used in:

  • Facial oils and antioxidant serums

  • Creams and soothing balms

  • Lip balms and under-eye treatments

  • Scalp and beard conditioning oils

  • Sensitive skin and baby care products

Avoid using in:

  • Emulsions heated above 40°C

  • Water-based products unless combined with a solubilizer

  • Soaps, unless added after saponification as a superfat

Ideal Usage Rates

FAQs

Is squalane safe to use around the eyes and lips?
Yes. It is gentle, non-irritating, and commonly used in lip care, eye creams, and baby skincare.

Can I use squalane in water-based products?
Only if it is emulsified or paired with a solubilizer. Squalane is oil-soluble.

Is squalane considered a luxury ingredient?
Yes. It is used by many high-end, minimalist, and clinical brands due to its smooth texture and skin affinity.

What skin types benefit the most from squalane?
All skin types can benefit, particularly those that are dry, sensitive, acne-prone, or maturing.

Can I label it as plant-derived or natural?
 Yes, provided it is derived from olive or sugarcane and appropriately documented.

Final Thoughts

Squalene is more than just another skincare oil. It is a lipid your skin already knows.
 By choosing olive-derived squalane, you embrace a stable, gentle, and highly compatible ingredient that performs beautifully in clean and effective skincare formulations.
