Ceramides Skin Benefits:
Moisturizing
Soothing

Similar to fatty acids, ceramides are a type of lipids found in cell membranes. A high concentration of ceramides is located in the epidermis- the outermost layer of skin cells. This is to help the skin retain moisture and protect against water loss. Unfortunately, the amount of ceramides present in the skin decreases with age, which over time can lead to dry and flaky skin. 1

As a way of counteracting this age-related pattern, ceramide products may work to improve skin barrier function and maintain skin-hydration. In addition, topical application of products containing ceramides have been suggested to provide soothing properties that can help to alleviate dry skin. The hydrating benefits of ceramides in skin care are most often found in moisturizers, facial cleansers, eye creams, sunscreens, lipsticks, and foundations. 2
