The key to keeping your skin supple and hydrated is keeping water trapped in the skin. In fact, keeping water in—and environmental stressors out—is one of the skin’s primary responsibilities. When your skin doesn’t, or when the barrier is compromised, something called transepidermal water loss happens. It’s a mouthful, but essentially what’s happening is the water in your epidermis evaporates into the air around you, leaving your skin dry, irritated, and angry. And it might be happening to you—especially given we’re in the throes of winter—if you’re not protecting your skin well enough.
So, yeah, transepidermal water loss doesn’t sound great, but how exactly do you prevent it from happening? Well, ceramides do the trick—in fact, their your body’s natural barrier from water loss. And you can support your internal ceramide levels with a skin care supplement.
