The light facial oil the experts keep suggesting to people who are nervous about oils. What it does, how it differs from squalene, where it comes from, and what 5 skincare experts said about it on camera.
Facial oils can feel like a gamble. Will it break you out? Is it really a hydrator? Then there is squalane, a name one letter away from squalene, which does not help. And there is the question nobody likes to ask out loud: did this come from a shark?
The experts' answer is simpler than the internet's. They like it, most of all for dry skin, for its light texture and for being gentle. It is the oil they keep suggesting to people who are nervous about oils.
Squalane has a Guru Score of 80%, and the one reservation on camera was about a product's added fragrance, not the squalane in it. Below, what the experts said sits right next to what the studies found, including the squalane versus squalene question and where the bottle on your shelf actually comes from.
Squalane is a light, stable oil used as an emollient: it softens and smooths dry skin. The experts we track recommend it, mostly for dry skin. It is the hydrogenated form of squalene, an oil your own skin makes, and that change makes it less prone to oxidation [2, 3]. The research on squalane itself is mostly lab work, so the case for it rests on how it behaves as an oil rather than on big clinical trials.
| Question | What we found |
|---|---|
| What is it used for? | Softening and smoothing dry skin. It is an emollient oil [3]. |
| Do skincare experts recommend it? | Yes, mostly for dry skin and as a gentle first oil. |
| Squalane or squalene? | Squalene is the oil in your sebum. Squalane is its hydrogenated, more stable form, and it is what most skincare uses [1, 3]. |
| Does it clog pores? | We found no good human trial of squalane itself. The pore-clogging concern in research is about oxidised squalene [6]. |
| Is it from sharks? | It can be. Shark liver is the traditional source, and olive oil and sugarcane are plant alternatives [4, 5]. The label may not say which. |
| Is it a hydrator? | Not in the way hyaluronic acid is. It is an oil that softens the surface, not a humectant that draws water in [3]. |
Squalane is a clear, light oil with no scent. It is made by hydrogenating squalene, an oil found in plants, in shark liver and in your own skin, where it makes up about 13% of sebum [1, 3]. Hydrogenation removes the double bonds in the molecule, which makes it less prone to oxidation than squalene [2, 3].
In a moisturiser it works as an emollient. Emollients are oils and lipids that improve how soft, flexible and smooth your skin feels [3]. That makes squalane a different job from a humectant like hyaluronic acid, which draws water in, or an occlusive like petrolatum, which sits on top and slows water loss [3].
Kelly Driscoll and Dr. Vanita Rattan both call squalane skin identical. The research puts it a little more carefully: what your skin actually makes is squalene [1]. Squalane is its close, more stable relative.
Here is what each of them said on camera, with a link to the moment they said it.
Squalane Oil is one of the lightest facial oil textures out there and it is also skin identical, which means our body kind of recognizes it as its own in a way. If you just want to dip a toe into the pool, you don't want to jump all the way in, this is where I suggest you start because it's the lightest one, it's the most skin respectful one.Watch ▸
A moisturizer with squalane can really help in improving your dry skin. Squalane is really good for dry skin. It feels very soothing, moisturizing, has anti-inflammatory properties.Watch ▸
Just 100% Squalene and pop this in. It's a skin identical ingredient, it's not going to irritate anybody if they have dry skin. Be heavy-handed with the squalene.Watch ▸
If you're putting castor oil on your skin for dry skin, you're much better off using many other things. Squalane Oil, coconut oil, I have no problem with the oils.Watch ▸
This might actually be one that's really good for oily skin except it does have fragrance in it which y'all know is not my preference and is a potential irritant and a common allergen in skincare productsWatch ▸
The experts are broadly positive, so the caveats are where the useful detail sits.
Honestly, not a great deal on squalane by itself. Most of the published work is on squalene, the oil in your sebum, or on squalane as a base for other ingredients. We found no large clinical trial of plain squalane on dry skin, so the experts' enthusiasm here rests on how it behaves as an emollient rather than on head-to-head studies.
Squalene is unsaturated, and sunlight oxidises it on the skin. Its first oxidation product, squalene monohydroperoxide, is one of the ways UV light causes oxidative stress at the skin's surface [1]. Squalane is the fully saturated form, which makes it more resistant to oxidation [2, 3]. That stability is why squalane, not squalene, is the version most skincare uses.
Dr. Vanita Rattan describes squalane as non-comedogenic, and Kelly Driscoll calls it the most skin respectful of the oils she suggests. We could not find a human trial that tested squalane itself, so treat that as expert experience rather than proven fact.
What the research does show is about oxidised squalene. In a rabbit ear study, squalene monohydroperoxide caused more blackheads than well-known pore-clogging cosmetic ingredients, while plain squalene caused fewer [6]. In skin cells, oxidised squalene switched on inflammatory signals linked to acne [7], and a small pilot study found more squalene and more of its oxidised form on acne-prone skin [8]. Squalane resists that oxidation [2], which is a sensible reason to think it is the safer of the two for breakout-prone skin. It is a reason, not a trial.
Dr. Aanchal MD mentions anti-inflammatory properties. Lab studies have looked at squalane protecting skin cells from UVA damage [2], but that work was done in cells in a dish, so it does not tell you what a squalane oil does on your face.
Squalene was first identified in deep-sea shark liver oil, and shark liver is still a major source [4, 5]. One review estimates that three to six million deep-sea sharks are killed for squalene each year, and calls the practice unsustainable [5].
There are plant routes too. Squalene occurs in olive oil, amaranth, rice bran and wheat germ [1], and it can be recovered from what is left over after olive oil is refined, then hydrogenated into squalane [4]. Another route ferments sugarcane with yeast and builds the molecule up from there [4]. Dr. Vanita Rattan describes the squalane she uses as plant harvested from olive oil and sugarcane, then hydrogenated in a lab to make it more stable.
Chemically, squalane is the same molecule whichever route made it. If where it comes from matters to you, look for a product that names a plant or sugarcane source, because the ingredient list alone will just say squalane.
Squalane comes as a plain oil and as an ingredient in moisturisers, serums and cleansers. As a plain oil, a few drops go a long way. Like any oil it works on the surface, so it suits the end of a routine, over your water-based steps.
Cleanse, apply any water-based serum, then press in a few drops of squalane, or use a moisturiser that contains it. In the morning, finish with sunscreen. Kelly Driscoll suggests it as the oil to start with if you are new to facial oils.
This is where the experts are keenest. Dr. Aanchal MD recommends a moisturiser with squalane for dry skin, and Dr. Vanita Rattan says to be heavy-handed with it on very dry skin. If your skin is very dry, a heavier occlusive on top will slow water loss more than an oil alone [3].
Dr. Vanita Rattan rates squalane as a lighter choice than heavy oils like coconut oil, but for acne-prone skin she prefers lightweight gels and water-based serums to any oil. If you break out easily, try it on one area for a couple of weeks before using it all over.
Dr. Vanita Rattan suggests a light, fast-absorbing oil such as squalane instead of coconut oil for hair, partly because a heavy oil that runs from the scalp onto the face can trigger breakouts. We found no good studies of squalane on hair, so this one is down to expert experience.
Squalane is about as easy to pair as skincare gets. It is not an active ingredient, it does not exfoliate, and it is stable, so it rarely clashes with anything.
They do different jobs. Hyaluronic acid is a humectant that draws water into the skin, and humectants work best with something on top [3]. Apply the hyaluronic acid first, then squalane or a moisturiser over it.
Squalane is often the base oil in retinol products, including one in the list below. On its own it can sit alongside a retinoid routine as a gentle, fragrance-free oil. Bring the retinoid in slowly whatever you pair it with.
Squalane softens; occlusives such as petrolatum seal [3]. On very dry skin, or for an overnight slugging routine, squalane underneath and an occlusive on top gives you both.

79%Guru ScoreSqualane softens and smooths skin. It is an emollient, an oil that improves how soft and flexible skin feels [3]. It is the stable, hydrogenated form of squalene, an oil your skin makes naturally [1, 3]. The skincare experts we track recommend it, mostly for dry skin.
Squalene is the unsaturated oil found in your sebum, in shark liver and in some plant oils [1]. Sunlight can oxidise it on the skin. Squalane is squalene that has been hydrogenated, which makes it saturated and more resistant to oxidation [2, 3]. That stability is why squalane is the version most skincare uses.
It may be a reasonable choice, but it is not proven. Dr. Vanita Rattan calls it non-comedogenic, though for acne-prone skin she still prefers gels and water-based serums. The research concern is about oxidised squalene, which caused blackheads in an animal study [6], and squalane resists that oxidation [2]. Test it on one area first.
We found no human trial testing squalane itself. Some experts describe it as non-comedogenic, and its stability is a sensible reason to expect it to behave better than squalene, whose oxidised form clogged pores in a rabbit ear study [6]. Everyone's skin differs, so if you break out easily, introduce it slowly.
It can be. Shark liver oil is the traditional source of squalene, and one review estimates three to six million deep-sea sharks are killed for it each year [5]. Plant routes exist too, from olive oil residues and from sugarcane fermentation [4]. The molecule is the same either way, so look for a brand that states a plant source.
Dry skin is where our experts rate it most. Dr. Aanchal MD recommends a moisturiser with squalane for dry skin, and Dr. Vanita Rattan says to be generous with it. As an emollient it softens and smooths [3]. On very dry skin, add a heavier occlusive on top, since that is what slows water loss most [3].
Yes. It is a stable, gentle oil and fits into a morning or evening routine. Use a few drops as the last step before sunscreen in the morning, or in place of a facial oil at night. If you are acne-prone, start on one area and build up.
They do different jobs, so many people use both. Hyaluronic acid is a humectant that draws water into the skin, while squalane is an emollient oil that softens the surface [3]. Humectants work best with something on top, so apply hyaluronic acid first and squalane or a moisturiser over it.
Yes. Squalane is often the base oil in retinol products, and on its own it adds no exfoliation or irritation of its own. It can be a gentle oil to use in a retinoid routine. Introduce the retinoid slowly, whatever you pair it with.
Some experts suggest it. Dr. Vanita Rattan recommends a light, fast-absorbing oil such as squalane instead of coconut oil, partly because heavy oil from the scalp can cause breakouts on the face. We found no good studies of squalane on hair, so this is expert experience rather than tested evidence.
We found no research on using squalane on the skin during pregnancy, and none flagging a concern. It is not an active ingredient like a retinoid. Even so, check with your doctor or midwife if you are unsure about anything in your routine while pregnant or breastfeeding.
The dermatologists among our experts mostly do. Dr. Aanchal MD recommends it for dry skin, and Doctorly would pick it over castor oil. Dr Dray's reservation was about a squalane product's added fragrance, not the oil itself.
