Plant squalane is a fully saturated, stable version of squalene — a lipid your skin naturally produces but loses with age. Derived mainly from olives or sugarcane (as a more sustainable alternative to shark-liver squalene), it is hydrogenated to prevent oxidation and extend shelf life. Because it so closely mirrors your skin's own oils, it absorbs quickly and is accepted by virtually all skin types without greasiness or irritation.
Squalane works by replenishing the lipid content of the skin's outermost layer, helping seal in moisture and prevent transepidermal water loss. It also has natural antioxidant and emollient properties that soften the appearance of fine lines and protect the skin from environmental stressors. Because it's non-comedogenic and structurally similar to human sebum, it regulates oil balance rather than disrupting it.
Most commonly used as a standalone facial oil or blended into serums and moisturizers. Sugarcane-derived squalane has become the industry standard for purity and sustainability. Oral squalane capsules exist in some clinical nutrition contexts, though topical use has the strongest evidence base for skin benefits.
Squalene was first isolated from shark liver oil in the early 20th century and recognized as a component of human sebum. By the late 20th century, the cosmetics industry began sourcing plant-based squalene from olive oil byproducts, later switching to sugarcane fermentation for a more scalable, eco-friendly supply. Today, plant squalane is one of the most widely studied and used cosmetic ingredients globally.
