Definition
Ceramides are lipids (oils) found naturally in skin stratum corneum and are essential in supporting the skin epidermal barrier and retaining moisture at skin surface. Lower ceramide levels usually associate with compromised epidermal barrier, which is one of the factors usually found on skin with conditions such as acne-prone, eczema-prone. Sun exposure, harsh climates, and age also impact ceramide levels and can compromise your skin epidermal barrier function contributing to loss of water through epidermis.
