What Ceramide AP does

Helps skin hold on to water
Supports the skin's protective barrier
Helps formulas feel smooth and comfortable

Ceramides are lipids, or fats, that already sit in the outer layer of human skin. They help water stay in the skin and act as a kind of mortar between skin cells. Most ceramides used in skincare are made in a lab, which keeps supply steady. Ceramide AP is one of these skin-identical versions.

Formulators use ceramides to help a product support the skin's natural barrier. They are often paired with cholesterol and fatty acids, the other lipids skin uses to build its barrier. In a formula, ceramide AP feels smooth and soft rather than greasy, and it blends easily into creams, lotions and washes.

Good for

Suits dry, tight or easily irritated skin, and anyone who wants extra barrier support in daily care.

Frequently asked questions

Is ceramide AP the same as the ceramides already in my skin?

It is skin-identical, meaning it is the same type of lipid your skin makes. Results depend on the whole formula and your own skin, so give any new product some time of steady use.

Is ceramide AP okay for sensitive skin?

It is generally well tolerated, and it is commonly used in formulas for dry or sensitive skin. Still, any new product can cause a reaction in some people, so patch test on a small area first and stop if irritation appears.
