What's actually doing the work
Ceramides
Ceramide NP / AP / EOP / Skin Barrier Lipids
Lipid
Lipids constituting ~50% of the stratum corneum intercellular matrix. Together with cholesterol and free fatty acids, ceramides form the lamellar bilayer structure preventing transepidermal water loss (TEWL) and shielding against irritants and pathogens. Levels decline with age, dry skin conditions, eczema and UV exposure. Robust clinical evidence for barrier restoration and eczema management.
Squalane
Hydrogenated Squalene / Plant-Derived Squalane
Lipid
A saturated, stable form of squalene — a skin lipid that declines dramatically after age 30. Structurally identical to human skin's natural oil: non-comedogenic, non-irritating, suitable for all skin types. Unlike most plant oils, it is oxidatively stable and will not go rancid. Functions as emollient, mild occlusive, and antioxidant.
