Squalane
Squalane is a light, saturated oil made by hydrogenating squalene, one of the lipids in the oil skin makes itself. Hydrogenation keeps it stable in the bottle. In a formula it is an emollient that softens the surface and adds a thin layer to slow water loss.

01 · Routine fit
Where it can be useful.
Dry-feeling skin that needs a light oil layer, and routines where heavier oils feel greasy. Squalane softens the surface and helps slow water loss[1]. That is emollient support, not a replacement for a humectant.
02 · Read the whole formula
What to keep in view.
- Squalene is one of the main lipids in skin's own surface oil. Squalane is its hydrogenated, more stable form[1][2].
- Squalane adds no water. Layer it over a humectant such as glycerin or hyaluronic acid, or choose a moisturiser that combines them.
- Few studies test squalane on its own. Most of the evidence is formulation science and emollient reviews, so read bigger label claims with caution.

Why it was shortlisted ↗Questions, answered plainly
Before you add another step.
Is squalane the same as squalene?
No. Squalene is an unsaturated lipid found in skin oil and in some plant and fish oils. Squalane is the saturated form made by hydrogenation, so it is less likely to go off in the bottle.
Will squalane make my skin look oily?
It spreads thinly, but any oil can feel like too much on skin that already looks shiny. Start with a few drops, or with a moisturiser that contains it.
Where does squalane go in a routine?
After water-based layers, either as the last step or mixed into a moisturiser, so it sits over the humectants underneath.
