Squalane

A light oil that softens without feeling heavy. It is the stable version of squalene, an oil your skin makes.

Start here

Squalane is the oil I suggest to people who tell me oils break them out — light, odorless, close to what skin already makes, and it does not go rancid. A few drops over a moisturizer fixes dry, tight, flaking skin, including the peeling stage of a retinoid. It does not hydrate: it smooths the surface and slows water loss, but it adds no water, so use it over a moisturizer, not instead of one. The spelling is not a typo — squalene with an e reacts with air, squalane with an a is stable, and skincare uses squalane.

What It Is

−

Squalane is a colorless, odorless oil made of a single type of molecule: the fully saturated form of squalene, which the body produces on its own. Squalene is a meaningful part of your skin's oil, and it is also in olives, rice bran, amaranth and other plants. Squalene reacts with air. Oxidized squalene is unstable, smells, and is one of the sebum components linked to clogged pores and irritation. Hydrogenating it removes the reactive points, so squalane is stable for years, odorless, and feels dry rather than greasy. Most squalane now comes from olives or fermented sugarcane. Shark liver oil was the original source and some still is, which is why plant-source brands say so on the label. The finished molecule is identical either way.

How It Works

−

Squalane is an emollient. It fills the small gaps between the flattened dead cells at the surface, so rough skin goes smooth. That is physical, so skin feels different immediately. It is also close enough to your own oils that it spreads and sinks in instead of sitting in a slick.

It is mildly occlusive too. A film of oil slows water evaporating, which is how any facial oil helps dryness. Squalane is far weaker at this than petrolatum — a light film, not a seal — so use it as a finishing layer over a moisturizer.

Three words explain most of the moisturizer aisle. A humectant, such as glycerin, draws water in. An emollient, such as squalane, smooths the surface. An occlusive, such as petrolatum, seals water in. Squalane does the middle job well, the third weakly, the first not at all.

It is not an active ingredient. No good evidence it treats acne, fades pigmentation or changes wrinkles. Antioxidant claims borrow from research on squalene in sebum; squalane is saturated, which is what makes it stable and what stops it acting that way. What it offers is tolerability, texture, and very few reactions.

Here is where Squalane acts in the skin, and what the others do instead.

Emollients are oils and lipids that sit in the spaces between the cells of the outer layer, the mortar between the bricks. They fill those gaps rather than covering them over, so skin feels smoother straight away, water stays in and irritants stay out.

Squalane is an oil the skin already makes a version of, so it sits into the lipids between the outer cells rather than crossing them. It softens the layer it lands in.

These acids work at the surface. They break the bonds holding dead cells to each other, so the top layer sheds more evenly. Skin looks smoother and brighter, and anything applied afterwards gets in more easily.

A humectant draws water into the outer layer and holds it there. Skin holding more water is plumper and more flexible, and fine lines caused by dryness soften within minutes. Seal it with something on top or in dry air the water can simply evaporate away.

An occlusive sits on the surface and slows water escaping. It adds nothing to the skin; it stops what is already there from leaving, which is why it works best over damp skin.

The outermost layer, and the one every moisturizer is aiming at. It is dead — flattened cells stacked like bricks, with a mix of fats as the glue between them. That glue is what holds water in and keeps irritants out.

The outer layer, and the only one anything in a jar reaches. It renews itself constantly: a cell made at the bottom takes about a month to reach the surface and flake off. Most of what a skincare product does, it does here.

The living layer underneath, holding the blood vessels, the nerves and the collagen. It is where lasting change happens and it is hard to reach: most of what is sold for the skin never gets this far.

What It Treats

−

No strong evidence for any condition.

Not the Best For

−
Dry Skin (Xerosis)

Dry Skin (Xerosis)

Limited evidence

A light oil that is close to one the skin makes itself, so it sits comfortably on the face and rarely causes spots. It softens and adds a little seal. It replaces very little of what dry skin has actually lost, so it works as a finishing layer over a ceramide cream rather than as the moisturizer itself.

Forms

−

Squalane is sold pure, as a single-ingredient oil, and that is how most people buy it. It is the lightest of the common facial oils, so people who dislike oils tolerate it. As a cleansing oil it dissolves sunscreen and makeup and rinses clean. Labels may name the source, olive or sugarcane; the molecule is identical. Good squalane smells of nothing, so return a cheap oil that smells strong.

Strengths

−

The percentage inside a cream is almost never listed, so what matters is how concentrated the product is and how much you use. Squalane has no dose-related irritation, so more is not riskier, only heavier.

Basics

−
When to Apply
Last, or nearly last. Oils block water-based products, so squalane goes after serums and moisturizer, and before sunscreen in the morning. Two or three drops pressed into slightly damp skin gets the most out of it.
How to Start
No build-up needed. A few drops at night, and a morning application too if your skin still feels tight. You can also mix it into moisturizer in your palm.
If It Irritates
Uncommon. If it stings, check whether it is pure squalane or a blend with essential oils or fragrance, the usual cause. Congestion in acne-prone skin happens, but far less than with heavier oils.
If It's Not Working
It contains no water, so it cannot fix dehydration alone. Put it over a moisturizer. If skin is cracked or scaly rather than merely rough, an ointment will do more.

Sample Routine

−

Here is where Squalane sits in a day, and what goes around it. Pick what you are treating and what your skin is like, and the rest of the routine changes to suit.

What to Expect

−
Day 1Week 1 to 2After 4 weeks
Immediate
Day 1
Skin feels smoother and looks less dull at once. The surface effect is the main thing squalane does.
Working
Week 1 to 2
Rough patches soften, flaking settles, and skin tolerates actives better.
Judge it here
After 4 weeks
If dryness, cracking or scaling is unchanged, squalane is not it. A humectant plus an occlusive is.

What to Avoid

−
  • Squalane conflicts with very little The mistakes are about where it sits in a routine.
  • Using it as your only moisturizer it contains no water and cannot add any. On dry skin the surface feels smooth while the dryness underneath continues.
  • Applying it before serums An oil layer blocks whatever comes after it. Squalane goes near the end.
  • Assuming it protects against sun it does not. Sunscreen goes on top in the morning.
  • Heavy layering on acne-prone skin squalane is one of the less troublesome oils, but any oil laid on thickly under makeup can contribute to congestion. Two or three drops is the dose.
  • The folklore oils are called universally pore-clogging. They differ a lot, and squalane sits at the well-tolerated end. Coconut oil causes most of the problems people blame on oils in general.

If You Stop

−

The smoothness fades within a day or two, because the effect depends on the oil being there. Nothing rebounds, and nothing gets worse than it was. Squalane does not suppress your skin's own oil production, and stopping it does not cause a surge of oiliness. That worry comes from an idea about heavy creams that does not hold up there either. Seasonal use, more in winter and little in summer, is reasonable.

Ask Your Doctor

−
If you break out in small itchy bumps
Uniform pinhead bumps on the chest, back or hairline after oils can be yeast-driven folliculitis, treated differently from acne.
If your skin stays cracked or scaly
Cracking despite daily use points to a barrier problem an emollient cannot fix.
If a rash appears where you applied it
A blended oil or fragrance is a likelier cause than squalane.
If you are caring for a wound or burn
These need specific aftercare, not a cosmetic oil.
If you have a fish or shellfish allergy
And the source is not stated. Ask first, since shark-derived squalane still exists.

How It Compares

−

Jojoba oil

The same

Also light and close to skin's own oils, and similarly well tolerated. Jojoba is a wax ester with a slightly heavier finish, and the two are largely interchangeable.

Mineral oil

Better

Cheaper and better at slowing water loss, but heavier on the skin and less popular cosmetically.

Four ointments on white: CeraVe Healing Ointment, a Vaseline jar, a petroleum jelly tube and Aquaphor16:9 hero for Petrolatum. Never cropped: the tone strip and the corner logo depend on the full frame.

Petrolatum

Different job

Far more effective at holding water in, and far greasier. Squalane is a daytime option in a way petrolatum is not.

Five coconut oil bottles and a jar on white, most labeled fractionated or organic virgin coconut oil16:9 hero for Coconut Oil. Never cropped: the tone strip and the corner logo depend on the full frame.

Coconut oil

Worse

Effective as an emollient, but clearly more likely to clog pores on the face. Squalane is the safer choice above the neck.

Ceramide cream

Different job

Ceramides help rebuild the barrier itself rather than only smoothing it. For eczema or a damaged barrier, the cream is the better tool.

Myths

+
  • "Squalane and squalene are the same thing." One hydrogenation step apart, and that step is the point. Squalene reacts with air, smells, and is linked to clogged pores. Squalane is stable.
  • "All squalane comes from sharks." Shark liver was the original source and some still use it, but most now comes from olives or fermented sugarcane.
  • "Oils moisturize your skin." Oils soften and slow water loss. They add no water.
  • "Squalane is an antioxidant." That research is on squalene, the unsaturated version, in sebum. Squalane is saturated, which is why it is stable and inactive here.
  • "Facial oils cause acne." Some do, some do not. Squalane is among the least likely, and often the one suggested to people who react to others.

Questions Patients Ask

+

What is the difference between squalane and squalene?

Squalene, with an e, is what skin makes, and it reacts with air. Squalane, with an a, is hydrogenated and stable. Skincare uses squalane.

Will squalane break me out?

One of the least likely oils to. Not impossible, especially under makeup, but if oils in general have caused problems, squalane is the one worth retrying.

Can I use it instead of moisturizer?

Not really. It has no water, so on dry skin it smooths the surface without touching the dryness. Use it over a moisturizer, or on damp skin.

Where does it go in my routine?

After serums and moisturizer, before sunscreen. Oils block water-based products applied after them.

Is it worth buying the expensive version?

Usually not. Pure squalane is a single, well-defined molecule, and the cheap single-ingredient oils are the same thing.

Is squalane vegan?

Most of it now is, made from olives or sugarcane, but not all. Shark-derived squalane still exists, so check the label states a plant source.
