Myth vs fact
- Myth
- Squalane is all your skin needs to stay hydrated.
- Fact
- No. Squalane softens skin and slows water loss, but it doesn't draw water in. That's the job of humectants such as glycerin or hyaluronic acid. And not everyone likes the feel of an oil.
What it is
Squalene is part of skin's own oil. Squalane is its stabilised form, which doesn't spoil easily. It's usually made from olives or sugarcane.
What it does
It forms a light layer that makes skin smoother and softer and slows some water loss. Research is mostly reviews and lab work.

Questions people ask
