Editor's note
Ceramides are barrier lipids — the structural fats that sit between skin cells and hold water in. When the barrier is intact, ceramides are abundant. When it is compromised, the ceramide pool depletes. Replenishing them topically works, within limits.

What ceramides are and what they do
Ceramides are a family of lipids that make up roughly 50% of the stratum corneum. They act as the mortar between skin-cell bricks, preventing water loss and blocking environmental irritants. Multiple types in one formula more closely replicate the natural barrier ratio.
Myth, meet fact
- Myth: More ceramides means a better product. Fact: Concentration matters less than formulation. A well-designed lipid matrix does more than a high-percentage thin serum.
- Myth: Ceramides only matter for dry skin. Fact: Oily skin can have a depleted barrier — relevant after exfoliation, retinoids, or damage.
- Myth: You need an expensive ceramide product. Fact: Some of the most effective ceramide formulations are drugstore products.
