Squalane

Hydrogenated squalene — a stable, lightweight emollient derived from olives, sugarcane, or formerly from shark liver. Structurally identical to skin's own lipids; absorbs without greasiness. Non-comedogenic and suitable for all skin types including oily/acne-prone. Stacks seamlessly with any active ingredient. A 3rd Wave staple in the oil-cleansing and barrier-repair routines popularized by Korean skincare communities.
