Squalane: comedogenic rating 1/5
Quick answer
No - squalane is about as close to non-comedogenic as an oil gets, rated 1/5 on published scales. It is one of the safest moisturizing oils for acne-prone skin and a common replacement for coconut oil and other heavy plant oils.

What squalane is
Squalane is a lightweight, odorless oil produced by hydrogenating squalene, a lipid your skin makes naturally. Cosmetic squalane comes from sugarcane fermentation or olives. Because it is fully saturated, it is extremely stable - it does not oxidize on your shelf or on your skin.
It mimics the skin's own sebum closely enough to feel 'familiar', softening without the heaviness or slip of most plant oils, which is why formulators reach for it in everything from facial oils to foundations.
Why it rates only 1/5
On classic comedogenic scales squalane scores around 1 out of 5. Its straight-chain, saturated structure spreads into a thin film rather than pooling in the follicle, and it does not react with sebum the way unsaturated or waxy ingredients can.
That said, 'low risk' is not 'impossible'. A small minority of very reactive, congested skin types report trouble with any oil, including squalane. The rating means most people - including most acne-prone people - tolerate it well.
How to use it if you are breakout-prone
Start with two or three drops at night as the last step, and give it two weeks before judging. Check the rest of the formula too: a squalane facial oil that also contains isopropyl myristate or coconut-derived esters brings the risk back through the other ingredients.
If you want the hydration of an oil with even less theoretical risk, mineral oil (0/5) and sunflower oil (0/5) sit even lower on the scale - though they bring less of the skin-identical feel that makes squalane popular.
Commonly found in

Common questions
Can squalane cause breakouts?›
It is uncommon. At 1/5 on the comedogenic scale, squalane is among the lowest-risk oils in skincare. If you break out after adding a squalane product, check the other ingredients before blaming the squalane itself.
Is squalane or squalene better for acne-prone skin?›
Squalane. Squalene (with an e) is the unstable, oxidizable version your skin produces; squalane (with an a) is hydrogenated for shelf stability. Oxidized squalene is associated with comedone formation, which is exactly what the hydrogenation step prevents.
Is olive-derived or sugarcane-derived squalane better?›
For pore clogging there is no meaningful difference - the molecule is identical. The source matters for sustainability and price, not for comedogenicity.
Related ingredients
Coconut Oil
Yes - coconut oil is highly comedogenic. It scores 4-5 out of 5 on published comedogenic scales (the Fulton assay rated coconut butter 4, practitioner lists rate unrefined oil 5) and is one of the most common pore-clogging ingredients found in moisturizers, cleansers and hair care.
Isopropyl Myristate
Yes - isopropyl myristate is one of the most comedogenic ingredients in cosmetics, rated 5/5. It is a synthetic ester used to make products feel lighter and spread better, and it is a well-documented breakout trigger.
Cetyl Alcohol
Mildly - cetyl alcohol rates 2/5, a low-to-moderate risk. Despite the name it is not the drying 'alcohol' in toners; it is a waxy fatty alcohol that thickens and stabilizes creams, and it is well tolerated by most skin, including many acne-prone people.
Lanolin
Rarely - pure lanolin rates only 1-2/5 on published scales, much lower than its rich, greasy feel suggests. The catch: some lanolin derivatives rate up to 5/5, so the family matters more than the word 'lanolin'.
