How To Protect Skin From Winter Dryness Internally
Ceramides are polar lipids, key lipids that are naturally present in our skin cells. They make up the barrier between the outside environment and our body, locking in moisture and protecting our skin from damage. If you think of the skin barrier as “bricks and mortar,” ceramides are part of the mortar holding it all together—50%, in fact. They play a huge role in keeping your skin moisturized, glowing, and youthful as their primary role in skin barrier function is to guard against water loss.
Ceramides, like most things present in our skin, can become depleted over time with age and through external aggressors. The best way to help replenish these naturally is through supplementation with phytoceramides or plant-derived versions.
And as a reminder, this does not mean you should skip the external hydration. Moisturizers are important for every skin type in every environment, but if you are able to help your skin internally, it just means that the external has an easier time doing its job. And, thus, you don’t necessarily need to switch to thicker creams come winter.
