What it does
- Softens skin and provides a non-greasy, fast-absorbing emollient feel.
- Helps reduce water loss and reinforces the lipid barrier.
- Improves the spreadability and finish of oil phases.
How it works
Squalene is a lipid naturally present in human sebum; squalane is its saturated, oxidation-stable form. Being biomimetic, it integrates smoothly into the skin's lipid layer to soften and reduce transepidermal water loss while feeling remarkably light. Modern squalane is commonly derived from olives or fermented sugarcane rather than shark liver.
Use level
- Typical use level
- widely variable; commonly 1–10% in formulas
Highly versatile: used from around 1% up to being a major part of the oil phase, and even neat as a facial oil. Typical formulated levels sit around 1–10%.
Formulation considerations
- Oil-soluble; part of the oil phase.
- Very stable to oxidation, heat and light (unlike squalene).
- Broadly compatible; improves slip and cushions actives.
- Sustainable grades are from olive or sugarcane.
What it pairs with & what to avoid
Pairs well with
- Humectants such as hyaluronic acid and glycerin (to seal)
- Ceramides and other barrier lipids
- Most oil-phase actives
Use with care / avoid
- Nothing significant; it is highly compatible
Regulatory status
Squalane is listed in the EU CosIng database and is a well-established, widely used emollient.
Common questions
Is squalane the same as squalene?
No. Squalene is the naturally occurring, less stable lipid; squalane is its hydrogenated, oxidation-stable version used in cosmetics.
Is squalane good for oily or acne-prone skin?
It is lightweight and generally well tolerated, and many oily-skin users find it comfortable, though individual responses vary.
Where does cosmetic squalane come from?
Most modern squalane is derived from olives or fermented sugarcane rather than shark liver.
