Squalane and squalene sound identical but behave very differently on skin, and the one your skin already makes is not the one you should be buying in a bottle.
Key takeaways
- Squalene is a natural oil your skin produces; squalane is its stabilised, hydrogenated form used in skincare.
- The one-letter difference reflects a real chemical change: squalane doesn't oxidise or go rancid the way squalene does.
- Squalane is a lightweight emollient that mimics skin's own oils without clogging pores for most skin types.
- Modern squalane is usually derived from olives, sugarcane or other plants, not shark liver as it once was.
- It layers well with almost every other ingredient and suits nearly all skin types, including oily and acne-prone skin.
