About
A natural skin lipid that softens and protects the barrier. Very well tolerated; the only real downside is that the unhydrogenated form can oxidize, so squalane is often preferred.
Function
Skin benefits
- Skin-identical lipid emollient
- Reinforces skin barrier
- Light, non-greasy feel
Known concerns
- Pure squalene oxidizes quickly and may go rancid
- Most products use squalane (hydrogenated form) for stability
