When it comes to moisturizing skincare ingredients, hyaluronic acid tops ingredient lists—and skincare enthusiasts’ minds—as a classic hydrator. But there's another ingredient that has similar thirst-quenching properties, and it's called squalane. Squalane (not to be confused with squalene with an “e”—more on that coming) is used in several skincare formulations and is brimming with beauty benefits. To learn everything there is to know about the ingredient, along with how it differs from squalene, we spoke with Toronto-based, board-certified dermatologist Dr. Geeta Yadav of Skin Science Dermatology.

What is squalane?

To define squalane, it's important to first understand how it differs from squalene (with an “e”). Squalene is a lipid in the skin that makes up about 12% of sebum, i.e. oil. Squalane (with an “a”) is a stabilized, saturated derivative of squalene. "Squalene is less stable than squalane and can oxidize when exposed to free radicals (like UV radiation)," Yadav says. "This can result in squalene peroxide, which can be comedogenic and cause acne." But by converting squalene into squalane, it becomes more shelf-stable, easier to formulate into skincare products, and less likely to clog pores.

As we age, natural squalene production decreases, which can result in rougher and dryer skin, according to Yadav. Incorporating products that contain squalane into your skincare routine can help supplement this and yield softer, more hydrated skin. But how is the ingredient different from other skin hydrators, like hyaluronic acid? While both are naturally occurring, hyaluronic acid is a humectant that helps pull water into the skin while squalane is an emollient that forms a protective barrier on the skin in order to prevent water loss.

How does squalane benefit the skin?

Squalane provides a number of benefits—namely, protecting the skin barrier from moisture loss. "As a lipid, squalane helps restore the moisture barrier and seal in hydration for more nourished skin," Yadav says. By mimicking our skin's natural sebum, the ingredient can help to restore natural oils, particularly for those with dry skin.

These positives apply to more than just skin—squalane can benefit hair and nails, too.

Squalane also comes with antioxidant benefits, serving as a skin protector against UV and other oxidative stress, says Yadav. One study notes that squalane's antioxidant properties can help fight free radical oxidative damage in the skin, which have been linked to the appearance of fine lines, sun spots, and other signs of aging.

Who should use squalane?

Unlike other emollients that may only be suited for dry skin types, squalane is non-comedogenic (meaning it won't clog pores), making it a fine option for those with oily or acne-prone skin. Not only can it provide this skin type with those aforementioned moisturizing, antioxidant benefits, but it can also help “trick” your oily skin into believing that it has enough of its natural oils, which can stabilize sebum production for better-balanced skin.

Those who have a damaged moisture barrier due to either over-exfoliation or inflammatory skin conditions like eczema or psoriasis may benefit from incorporating squalane into their skincare routine, too. "Squalane has anti-inflammatory properties that can be quite soothing on irritated skin, including eczema patches," Yadav says.

How do you look for squalane in skincare products?

Squalane can be harvested from shark livers as well as from plant-based options like olives, rice bran, and sugar cane. If using non-animal-derived products is important to you, look for labels that use language like “vegan” or “100% plant-based” or ones that specifically call out the source of the squalane.

Squalane is available in a variety of skincare products including moisturizers, serums, and cleansers, so how you use it will depend on the product. "I like recommending the use of squalane as a face oil or as a moisturizer, to be applied after cleansing and serum application," Yadav says.
