Ceramide AS

What Ceramide AS is & what it does

A barrier-supporting ceramide that helps seal in moisture and strengthen the skin's protective layer. It improves softness and resilience.

What does Ceramide AS do in skincare?

Ceramide AS is one of the ceramide lipids commonly used as a skin-conditioning and barrier-supporting ingredient. Ceramides are naturally part of the skin's outer barrier, and adding them to a formula may help support a smooth, comfortable feel. It is often paired with other ceramides and lipids.

Is Ceramide AS natural or synthetic?

Ceramides like Ceramide AS used in cosmetics are most often produced synthetically or through biotechnology to match the lipids found in skin. The version used in a product depends on the manufacturer. Whatever the source, the goal is to mirror the skin's own ceramides.

Is Ceramide AS vegan?

Ceramide AS used in modern cosmetics is commonly produced synthetically or by fermentation, which can make it suitable for vegan formulas, though some ceramides have historically been animal-derived. The source depends on the specific manufacturer. Check the brand's information or vegan certification to confirm.
