Ceramides
세라마이드 · 神經醯胺
Also known as: Ceramide NP, Ceramide AP
What it actually does
Fat-like lipids that occur naturally in skin. Ceramides are commonly added to cosmetic formulations to help support the skin barrier and reduce the feeling of moisture loss.
How to use it
Look for it in your moisturiser or cream — apply as the last hydrating step, AM and PM.
The science, in plain English
Lipids that make up a significant portion of the outer skin barrier. Replenishing them in a formulation is associated with reduced visible water loss and reactivity.
Myth vs reality
Using more ceramide-containing products is not automatically better — formulation ratio with cholesterol and fatty acids is considered more relevant than raw ceramide content.
Limitations of the evidence
Well-supported as a barrier-support ingredient class in cosmetic science, though results depend on the full formulation and ratio with cholesterol and fatty acids, not the presence of ceramides alone.
Who may need extra caution
Generally well tolerated, including on eczema-prone skin, but is not a substitute for prescribed treatment.
