If your skin ever feels tight, flaky, or unexpectedly reactive, you're not alone. Many people run into these issues even with a consistent skincare routine. One often-overlooked cause is a drop in ceramides. Ceramides are naturally occurring lipids that play a critical role in maintaining a healthy skin barrier.
