Squalane
A lightweight, stable oil derived from squalene that mimics your skin's own lipids to soften and protect the moisture barrier.
Squalane is a saturated, shelf-stable form of squalene, a lipid your skin naturally produces as part of its sebum. Because the molecule is hydrogenated, it resists oxidation far better than its precursor, making it practical for skincare formulations. Most squalane today is sourced from olives or sugarcane rather than shark liver, so look for plant-derived versions if that matters to you.
In a formula, squalane functions as an emollient. Rather than drawing water into the skin the way a humectant would, it sits within the upper layers of the stratum corneum and helps fill the gaps between skin cells, reducing moisture loss through evaporation. It has a dry, non-greasy finish and is generally formulated at concentrations between 1% and 100% (it works beautifully as a standalone oil). Its lightweight texture means it layers well under sunscreen or makeup without pilling.
Squalane suits most skin types, including skin that tends toward oiliness, because it closely resembles what your skin already produces. It pairs nicely with humectants like hyaluronic acid or glycerin: the humectant attracts water, and the squalane helps keep it there. It also works well alongside active ingredients such as retinoids or exfoliating acids, where a gentle buffer can support comfort during adjustment periods.
Honest limits: squalane is a reliable barrier-support ingredient, but it is not an active treatment for specific skin concerns. It won't increase cell turnover, brighten pigmentation, or address breakouts on its own. If your skin feels persistently dry or uncomfortable despite consistent moisturiser use, that is worth raising with a skincare professional to understand what else might be going on.
