Squalane

MoisturiserBarrierSensitive skin

A lightweight, non-comedogenic oil that mimics skin's natural sebum. The 'safe' moisturiser — almost no one reacts to it.

EvidenceModerate

Strong as a non-irritating moisturiser. Moderate for atopic dermatitis support, sensitive skin barrier repair. Effects: immediate to days.

Squalane is the hydrogenated, shelf-stable form of squalene — a lipid the body and certain plants make naturally. Olive- and sugarcane-derived squalanes are now the dominant sources (shark-liver squalene is the historical, now-avoided source). It's lightweight, deeply moisturising, non-comedogenic, and doesn't trigger reactions in most sensitive-skin presentations. Excellent as a final occlusive step over serums, as a face oil, or for rosacea / eczema-prone skin where standard moisturisers irritate.
