  intro: "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's compromised — by over-exfoliation, stripping cleansers, environmental stress, or age — the ceramide pool depletes and the barrier becomes leaky. Replenishing them topically works, within limits. Applied ceramides don't become your skin's ceramides, but they do provide a temporary lipid matrix that the barrier can use while it repairs itself. The ceramide bandwagon is mostly real. The products range from excellent to barely-there. Below is everything we've published on the subject.",
