Squalene
Squalene is a natural lipid found in human sebum and various plant and animal sources. It acts as an emollient, helping to moisturize and soften the skin. However, it is unstable and prone to oxidation, which can lead to skin irritation or clogged pores.

Frequently asked questions
- What is the difference between squalene and squalane?
- Squalene is a natural lipid found in human sebum, but it is unstable and oxidizes quickly. Squalane is a hydrogenated form of squalene, making it stable, non-oxidizing, and more suitable for cosmetic formulations.
- Why is squalene less common in skincare than squalane?
- Squalene's instability and tendency to oxidize make it less desirable for skincare products compared to its hydrogenated, stable form, squalane. Oxidation can lead to product degradation and potential skin issues.
