Ingredient
Squalene
Emollient (unsaturated) · INCI: Squalene
How we read it
Highly comedogenic
A known pore-clogging ingredient. Avoid if you're acne-prone.
Why we read it this way
The unsaturated form of squalane (note the 'e'). Unlike stable squalane, squalene oxidizes and is listed as pore-clogging.
The nuance
Don't confuse with Squalane (with an 'a'), which is the stable, non-flagged version.
