Squalane

By Nur → Last verified 9/26/2026

What it is

Squalane is a stable, skin-identical oil, usually plant-derived from olives or sugarcane in modern formulas, used as an emollient that softens skin and helps prevent moisture loss without feeling heavy or greasy.

What the evidence says

Squalane works as an emollient, filling in gaps between skin cells and smoothing texture. Concentration can be disclosed and meaningful, S.NATURE's formula confirms a high, specific 150,000ppm concentration, well above a trace addition. Worth knowing: marketing language sometimes implies ceramide content when the real, confirmed formula is built on squalane and cholesterol instead. AESTURA's Hydro Essence repeatedly references ceramides in its marketing, but its verified ingredient list contains no literal ceramide entry.

Who it's for

Nearly all skin types, including oily and acne-prone skin, since it's a lightweight emollient rather than a heavy occlusive oil.

Worth knowing

No specific group needs to avoid squalane, it's broadly well-tolerated across skin types.
