Squalane

Squalane is a moisturising ingredient that softens and smoothes the skin while replenishing lipids.

What are the benefits?

Its fatty acids and antioxidants help to keep the skin in good condition. Its compatibility with skin lipids is due to the fact that human sebum contains 25% squalane.
Since it is heavily saturated, squalane is less likely to degrade in the presence of air than less saturated squalene.
