Squalane, the emollient that speaks your skin’s language

By Jeremy Fain, founder of Restelys. Updated 17 October 2026. 3 sources cited.

Our skin makes squalene itself. Olive squalane is its stable version: that is why it softens without ever feeling heavy.

Human sebum contains a significant share of squalene, a molecule the skin produces to stay supple and protected. Researchers consider it one of the most characteristic lipids of the skin surface.

Squalene oxidises quickly in air; squalane, obtained from olives and then stabilised, keeps its qualities without that drawback. It spreads easily, sinks in without a greasy film and adds softness, which makes it an emollient of choice.

In our body lotion it brings the silky feel you notice from the first application; in our conditioner it coats the fibre and makes detangling easier.
