You've probably seen it on every "holy grail" skincare list for the last three years. It’s in your serums, your high-end moisturizers, and even your hair masks. But if you tip the bottle, it looks like oil, feels like oil, and spreads like oil. So, is squalane an oil?
Well, yes and no. Mostly no.
Actually, it's a hydrogenated version of a lipid your own body produces naturally. If we’re being pedantic—and in skincare, we usually are—it’s technically a saturated oil, but its molecular behavior is so distinct from your typical kitchen-counter olive oil that calling it just an "oil" feels like a bit of a lie. It's more of a skin-identical supplement.
The Chemistry of Why Squalane Isn't Just "Grease"
To understand the confusion, we have to talk about squalene with an "e." Your sebaceous glands produce squalene. It makes up about 10% to 12% of your skin’s sebum. It’s the good stuff that keeps your skin barrier from falling apart. But there is a massive problem with squalene: it’s incredibly unstable. If you leave a bottle of pure squalene on your shelf, it will oxidize faster than a sliced apple. Oxidized sebum is a nightmare for pores; it's thick, sticky, and often leads to the very breakouts you’re trying to avoid.
That is where squalane with an "a" comes in.
Through a process called hydrogenation, scientists turn the unstable squalene into the stable squalane. This process makes it shelf-stable for years. It won't oxidize on your face. Because it is saturated, it doesn't have those double bonds that go "rancid" when exposed to oxygen.

It’s thin. Watery, almost.
When you drop it onto your skin, it doesn’t sit on top like a heavy blanket. It sinks in. Most plant oils like jojoba or almond have a complex mixture of fatty acids, waxes, and unsaponifiables. Squalane is just one thing. It’s a 100% pure hydrocarbon. This simplicity is why it plays so well with others.
Where Does It Come From Anyway?
History has a dark side here. For a long time, the primary source of squalene was shark livers. It was efficient for the industry but devastating for the oceans. Thankfully, the skincare world has largely moved on, though you should always check for "100% plant-derived" on the label just to be safe.
Today, most of the squalane you buy comes from olives or sugarcane.
There’s a bit of a nerd-war between the two. Olive-derived squalane is great, but it can occasionally have purity issues depending on the harvest. Sugarcane squalane, popularized by brands like Biossance (owned by Amyris), is created through a fermentation process using yeast. It’s remarkably consistent. It’s also considered more sustainable because it doesn't rely on olive crop fluctuations.
The result is a clear, odorless liquid that feels weightless.
The Pore-Clogging Myth
If you have acne-prone skin, the word "oil" is terrifying. You’ve likely spent years scanning labels for "oil-free" everything. So, when people ask is squalane an oil, they are usually really asking: "Will this give me cystic acne?"
Generally, no.
Squalane is non-comedogenic. Because it mimics your skin’s natural lipids, your pores don't see it as a foreign invader. It doesn't trigger that "foreign body" inflammatory response that thicker oils like coconut oil might. In fact, many people with oily skin find that using squalane actually helps balance their natural oil production. If your skin thinks it has enough lubrication, it sometimes slows down its own sebum factory.
It's a weird paradox. You add "oil" to stop being oily.
How to Use It Without Looking Like a Deep-Fryer
Don't just slather it on and hope for the best. Skincare is about the order of operations.
Since squalane is an emollient—meaning it fills in the cracks between skin cells—it works best when applied after your water-based serums but before (or mixed into) your heavy cream.
- Dampen your skin with a mist or water.
- Apply your hyaluronic acid or Vitamin C.
- Warm two drops of squalane in your palms.
- Press it into your cheeks and forehead.
- Follow with moisturizer if you’re extra dry.
Honestly, during the summer, a lot of people skip the heavy moisturizer entirely and just use squalane. It provides that "glass skin" glow without the heaviness of a traditional cream. It’s also a secret weapon for hair. If you have those flyaways or frizzy ends, a tiny—and I mean tiny—amount of squalane can smooth them out without making your hair look like it hasn't been washed in a week.
Comparing Squalane to the "Heavy Hitters"
How does it stack up against things like Marula or Argan?
Argan oil is rich in Vitamin E and fatty acids. It’s fantastic, but it’s "oily." You feel it. You smell it. Squalane is more of a "dry" oil experience. Marula is thicker and more antioxidant-heavy, which is great for anti-aging but can be a bit much for someone with a greasy T-zone.
Squalane is the middle ground. It’s the "universal donor" of the skincare world.
It’s also surprisingly good for eczema and rosacea. Because it is so chemically simple, the risk of an allergic reaction is nearly zero. It doesn't have the fragrances or complex proteins found in nut oils. If your skin is currently "angry"—maybe you overdid it with the Retinol or a chemical peel—squalane is the safety net. It helps repair the lipid barrier without introducing irritating actives.
Is Squalane An Oil? The Final Verdict
If you’re talking to a chemist, it’s a saturated branched-chain hydrocarbon. If you’re talking to a beauty blogger, it’s a face oil. If you’re talking to your skin, it’s just "home."
It fills a specific niche: it provides the benefits of an oil (occlusion, softening, lipid replacement) without the drawbacks (oxidation, greasiness, clogging).

Actionable Steps for Your Routine
If you're ready to integrate this into your life, start small. You don't need a $100 bottle. High-purity squalane is a commodity chemical, meaning the stuff from a budget brand like The Ordinary or Inkey List is chemically almost identical to the stuff in luxury bottles.
- Check the source: Look for "100% Plant-Derived" or "Sugarcane Derived" to ensure it's vegan and sustainable.
- Patch test: Even though it’s low-risk, always test it on your jawline for 24 hours.
- Mix it up: If you find it too shiny, add one drop to your foundation. It gives a dewy finish to matte formulas that feel too "flat" on the skin.
- Night use: If you're still scared of the "oil" tag, use it only at night. You'll wake up with skin that feels noticeably more "bouncy" and hydrated.
Stop thinking of it as a grease and start thinking of it as a biocompatible sealant. Your skin barrier will thank you.
