Squalene

Squalane is a highly stable, lightweight, and skin-friendly emollient widely used in cosmetic and personal care formulations. It is a saturated and hydrogenated form of squalene, most commonly derived from olive oil or other plant sources, making it suitable for modern, sustainable skincare products.

Squalane closely mimics the skin’s natural lipids, which allows it to absorb quickly, provide long-lasting hydration, and improve skin softness without leaving a greasy or heavy residue.
