Skin Barrier 101: For Dry Skin

If you have dry skin, you should focus 100% on your skin barrier (AKA “Stratum Corneum”). This is the “dead” layer of skin that acts as a protective shield, keeping moisture in and harmful elements out. When this barrier is compromised, your skin can become dry, irritated, and more prone to sensitivity. Let’s learn about the anatomy of the skin barrier:

Skin Barrier Stratum Corneum

To strengthen and protect this layer, use products with ingredients like glycerin, ceramides, cholesterol, and fatty acids. These ingredients help to replenish moisture, repair the barrier, and keep your skin feeling soft and hydrated. Prioritizing your skin barrier will help ensure that your skin stays healthy and well-moisturized.

Damaged Skin Barrier

It’s very important to keep our stratum corneum happy and functioning so it can fully protect us. If it's too thin or too damaged to function, it can't keep irritants out or water in. When this happens, our skin becomes inflamed, red, itchy, flakey, and burning. It’s important to recognize a damaged skin barrier (AKA damaged stratum corneum). When damaged, the skin needs some “time off” in order to heal (like you need time for a broken bone to heal!). If you have a damaged skin barrier, use only gentle moisturizer, cleanser, and sunscreen for 2 full weeks (for the stratum corneum for fully restore). When our stratum corneum is healthy and hydrated, our skin cells can keep water in and the bad guys out!
