A natural component of our skin’s outer layer, it helps our skin retain moisture and prevent transepidermal water loss (TEWL)
. When our skin’s moisture barrier is damaged either from the elements or from overexfoliation
, the level of ceramides in our skin also decreases, so it’s important to replenish that via skincare products that contain this ingredient (source, source)
Studies have also shown that formulas containing ceramides are more effective at decreasing TEWL, improving skin hydration levels and skin barrier health compared to traditionally used emollients like cold creams (source, source)
So whether you have dry skin, irritated skin, or just to maintain the health of skin, ceramides are a wonderful ingredient to have in your skincare products.
