Actives like retinol, vitamin C and exfoliating acids dominate skin care conversations, while ultra-hydrating ingredients are often left on the sidelines. Think about it: Do you know anything about or have you even heard of squalane? While under the radar, squalane is the cornerstone of many moisturizers and serums due to its ability to reinforce the skin barrier, and although it may not be as buzzy as hyaluronic acid, the ingredient is a worthy addition to your routine if you’re looking to soften and strengthen your complexion.
What’s the difference between squalane and squalene?
Before diving into the specifics of squalane, it’s important to know the difference between it and another popular compound, squalene (with an e). “Both ingredients are moisturizing agents and function similarly, but they are different,” says Dr. Ryan Turner, board-certified dermatologist and founder of TRNR Skin. “Squalene is found in plants, animals (famously, shark liver) and our own bodies produce it. However, it is also notoriously unstable making it unsuitable for use in skin care products as it can rapidly degrade,” he explains. “Squalane is derived from squalene — the latter ingredient gets hydrogenated, meaning squalene was converted from an unsaturated to a saturated oil by the addition of hydrogens. Squalane is much more stable and therefore the better choice for use in skin care.”
Benefits of squalane
1. Moisturizing
Ron Robinson, a cosmetic chemist and the founder of BeautyStat, explains that squalane is an emollient- and antioxidant-rich lipid that mimics the skin’s own natural oils, allowing it to intensely moisturize all skin types.
2. Supports the skin barrier
“Lipids like squalane are critical for proper skin function,” Turner says. “These lipids play an important role in our skin — they act like the grout between the bricks of our skin cells, preventing water loss and keeping skin moisturized while blocking external irritants from getting through the barrier. Without lipids like squalane, you’re at risk of dry, sensitive, irritated skin.” He adds that introducing squalane to your routine can greatly reinforce the skin barrier to keep it comfortable and balanced, something that’s especially necessary during the dry winter months.
3. Antioxidant protection
The benefits of the ingredient don’t end there, though. “Additionally, squalane has antioxidant properties, helping to protect your skin against free radical damage emitted by environmental pollution and UV — free radical damage causes premature aging,” Turner tacks on.
Who should use squalane?
While some skin care ingredients aren’t suitable for all skin types, Turner assures that squalane is something that everyone can benefit from. “Though it is an oil, it can be safely used by acne-prone skin because it is biomimetic, meaning it functions similarly to your skin’s natural sebum, and is non-comedogenic.”
It’s a common misconception that oily skin types don’t need a moisturizer — let alone an additional face oil — in their routine, but board-certified dermatologist Dr. Kiran Mian explains that “without enough moisture, oil glands often go into overdrive, producing more oil. That’s why adding an emollient, like squalane, to your skincare routine can help balance the skin.”
Best squalane skin care
Regardless of your skin type, integrating squalane into your regimen can lead to a softer, more supple and balanced complexion. Below you’ll find expert-recommended squalane moisturizers, serums, oils, cleansers and more.
“If you’re looking to try squalane in its purest form, this product from Biossance is a nice pick,” Turner says. “Squalane is the star of this line’s products, but this formula contains nothing but 100% squalane oil, making it ideal for those who have very reactive skin. Squalane is very gentle, and having it in a product solo means you can enjoy the ingredient’s nourishing and skin-balancing benefits without the risk of a reaction caused by any other ingredient.”
Squalane has been a signature ingredient in Kiehl’s products for decades, and the Ultra Facial Cream may just be the most well-known (and most loved) formula from the line. It's one of associate beauty editor Sophie Shaw's all-time favorite products and our pick for best moisturizer for combination skin.

“I’m a big fan of Paula’s Choice products because they are extremely well-formulated,” shares Turner. “This moisturizer in particular not only includes squalane, but five different ceramides, shea butter, urea and cholesterol to provide intensive nourishment to the skin.

While it may be tempting to load up on squalane-infused skin care to give your skin a hydrating boost, Mian suggests sticking to one or two products in your routine — and a favorite of hers is this unique oil-to-foam cleanser. “It deeply cleanses while supplementing the skin with hydrating, barrier-restoring ingredients like squalane and ceramides,” she says.
