Squalane
Also known as: hydrogenated squalene, plant-derived squalane, olive squalane
Squalane is the hydrogenated (stabilized) form of squalene, a lipid naturally produced by your skin. It's one of the most universally tolerated moisturizing oils available โ lightweight enough for oily skin, nourishing enough for dry skin, and unlikely to cause breakouts in anyone.
What It Does
Deep Dive
Squalane vs Squalene
Your skin naturally produces squalene as part of its sebum. Squalane is the hydrogenated, shelf-stable version used in skincare. The distinction matters: squalene oxidizes quickly and can be comedogenic, while squalane is stable and non-comedogenic.
Why It Works for Everyone
Squalane's molecular structure closely resembles human sebum, which means it absorbs quickly without feeling greasy. Its low comedogenicity rating makes it suitable even for acne-prone skin โ unusual for an oil. It provides occlusion (preventing water loss) without the heavy feel of petrolatum or heavier oils.
Sources
Historically sourced from shark liver oil, modern squalane is overwhelmingly plant-derived โ typically from olives, sugarcane, or rice bran. This is both more sustainable and cheaper. If sourcing matters to you, most K-beauty brands now specify plant-derived squalane.
How to Use It
Squalane can be used on its own as a final oil layer, mixed into your moisturizer, or used to buffer retinol application. A few drops are enough for the whole face. It's also excellent for cuticles, lips, and dry patches anywhere on the body.
