Ceramides vs Squalane
Two popular actives, side by side — no fluff.
Ceramides
aka ceramide NP, ceramide AP, ceramide EOP
Ceramides are lipids that make up roughly 50% of the skin barrier. They're not glamorous, rarely trend on social media, and don't promise overnight transformation — which is exactly why they work. Consistent use demonstrably improves barrier function, moisture retention, and skin resilience.
Squalane
aka 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 — lightweight enough for oily skin, nourishing enough for dry skin, and unlikely to cause breakouts in anyone.

| Concentration | Effective in combination with cholesterol and fatty acids in a ratio that mimics the skin's natural lipid composition (roughly 1:1:1 or 3:1:1). The specific ceramide type matters less than the overall lipid blend. Most effective in cream or balm formulations. | Used at 1-100% depending on the product format. Pure squalane oil is 100%. In serums and moisturizers, 2-10% is typical. It's very well tolerated — even pure squalane rarely clogs pores or causes breakouts. |
