Skin Thirsty? Squalane Is the ‘Big Gulp’ of Moisturizers for Dry Complexions

Hyaluronic acid is like the popular girl in school—the captain of the skin-care cheer squad, if you will. But as if plucked from a throwback cheer movie of your choosing: Another hydrating ingredient is giving it a run for its place in your skin squad, looking for v-i-c-t-o-r-y for your complexion. That ingredient is squalane.

Like hyaluronic acid, squalene (its base compound) is naturally made within your our bodies. "Squalene is a lipid in our sebum produced naturally by our own bodies," says Liana Cutrone, a skin therapist with Heyday. Also like hyaluronic acid, it tends to diminish within your body as you age—which is why it's a good addition to your skin-care products.

In skin-care formulations, squalene originally came from shark liver oil, which is obviously frowned upon for its sourcing. You can get it from plants, though—Cutrone points out that common sources include amaranth seed, rice bran, and wheat germs. Naissan Wesley, MD, FACMS, a board-certified dermatologist and Arbonne scientific advisory board member, adds that you can also find it from extra virgin olive oil. But squalene "must often be hydrogenated first to give it stability," she says—because it's not particularly stable on it's own. Squalane, however, is completely hydrogenated squalene, which is why it's more common on skin-care shelves. "Squalane is more commonly used as it's typically more stable in products," says Cutrone.

The reason you can find it on every shelf? It's super hydrating and calming on skin. "Squalane and squalene act as lubricants on the skin to help give it a soft, smooth appearance," says Dr. Wesley, who says they're both helpful for all skin types.
