Squalane is a clean skincare staple, praised for its ability to hydrate and support the skin barrier. But which products are worth the spend?
Walk into any beauty retailer or skim the ingredient lists online, and squalane is suddenly everywhere. It shows up in face oils promising hydration without breakouts, cleansers designed not to strip skin, and moisturizers positioned for sensitivity, aging, or barrier repair. The claims vary, but the ingredient stays the same. That ubiquity has raised a reasonable question for consumers: is squalane simply the ingredient of the moment, or has it earned its near-universal adoption?
Squalane is the stabilized form of squalene, a lipid the human body naturally produces to lubricate and protect the skin barrier. Over time, that internal supply declines. Natural production of squalene slows significantly after the age of 30,” Samantha Fisher, MD, a board-certified dermatologist, told Allure.
What squalane does for skin
In topical form, squalane stands out because it mirrors the skin’s own oils without behaving like a traditional occlusive. Lightweight and fast-absorbing, it helps reduce moisture loss while remaining suitable for acne-prone and sensitive skin. “Squalane is a great moisturizer as it is easily absorbed by the skin and prevents water loss from the skin,” Sapna Palep, MD, founder and medical director of Spring Street Dermatology told Today. “In addition, it is not a common irritant or allergen, so even the most sensitive skin is unlikely to react to it.”
Squalane functions primarily as an emollient, helping soften skin and reinforce the lipid barrier. Because it is non-comedogenic, it does not clog pores, making it appropriate for oily and acne-prone skin alongside drier or mature complexions. Dermatology guidance consistently notes that squalane supports hydration without heaviness, making it especially useful in routines that include potentially sensitizing actives such as retinoids or exfoliating acids.
Squalane sourcing
Just as important as how squalane performs is how it is sourced.
For decades, much of the global supply of squalene used in cosmetics came from shark liver oil. Research published in peer-reviewed journals estimates that producing one metric ton of squalene from shark liver oil historically required the killing of roughly 3,000 deep-sea sharks, whose livers contain exceptionally high concentrations of the lipid.
Conservation groups have further estimated that millions of sharks were killed annually at the height of this trade, with the majority of shark liver oil destined for cosmetics rather than medical use. Plant-derived squalene now accounts for more than 80 percent of global supply, driven by advances in fermentation and increased scrutiny of marine biodiversity impacts. Alternative sources include sugarcane, olives, and rice bran, which produce a molecule that is chemically identical to animal-derived versions.
Sugarcane-derived squalane, in particular, is produced through fermentation processes that convert plant sugars into stable lipids, allowing brands to avoid reliance on finite marine resources. Olive-derived squalane is frequently sourced from byproducts of the olive oil industry, embedding circularity into the supply chain while maintaining cosmetic-grade purity.
Clean squalane products
Squalane can be used alone, mixed into moisturizers, or applied over serums to reduce transepidermal water loss without interfering with absorption. These products offer standalones and blends featuring squalane in clean formulations.
