Hydrogenated Squalene
Quick verdict
Squalane is a oil with a low risk comedogenic profile (1/5) and safe irritancy (0/5). A stable, saturated oil that mimics the skin's natural sebum. Modern squalane is derived from sugarcane or olives, not sharks.
What is Squalane?
Squalane is the saturated, hydrogenated form of squalene — a hydrocarbon that occurs naturally in human sebum and in the oils of olives, sugarcane, rice bran and amaranth. The 'e' in squalene means it is unsaturated and oxidises quickly; the 'a' in squalane means it has been hydrogenated to a stable, non-rancid form ideal for skincare. Modern cosmetic squalane is overwhelmingly plant-derived (most commonly from sugarcane fermentation or olives), making it both vegan and ethical — historically it was harvested from shark liver, but reputable brands have abandoned that source.
Comedogenic Rating: What 1/5 Means for Your Skin
Squalane is rated 0–1/5 comedogenic. Because it mirrors the structure of human sebum, the skin recognises it as 'self' rather than as a foreign oil — there is no follicular blockage or inflammatory response. Even oily and acne-prone users typically tolerate it without breakouts. It is one of the few facial oils that is universally recommended across skin types.
Benefits for skin
- Restores the lipid layer without clogging pores
- Lightweight and fast-absorbing
- Anti-inflammatory and antioxidant properties
- Compatible with all actives — no interaction risks
Potential side effects & who should avoid it
Squalane is essentially side-effect-free. Allergy is vanishingly rare, and there are no known interactions with other actives. The only consideration is that some olive-derived squalane retains trace olive proteins; people with severe olive allergy may prefer sugarcane-derived versions.
Best for
- Dry
- Normal
- Combination
- Sensitive
- Acne-prone (well-tolerated)
Avoid if
No widely reported groups need to avoid this ingredient. Patch-test if you have a history of sensitivities.
How to use Squalane safely
Apply 2–4 drops as the final step of your evening routine, or mix into your moisturiser. Pairs safely with every active including retinol, vitamin C, AHAs and BHAs. Layered over a hydrating serum, it locks in moisture without the heaviness of butters.
