What is olive-derived squalane?

Olive-derived squalane is a botanical lipid extracted from olive oil. It closely mirrors the skin's own natural lipids, making it exceptionally biocompatible and well-tolerated -- even by sensitive and acne-prone skin. Squalane is non-comedogenic, fast-absorbing, and rich in antioxidants that protect the skin barrier and fight free-radical damage. Kosterina uses plant-derived squalane (not shark-derived) in our skincare formulations.
