Ceramides are naturally occurring lipids or fats found in skin cells. They make up 30-50% of the epidermis - the outermost layer of our skin also called the Stratum Corneum.
Ceramides can be categorised as two types - hydrophilic and hydrophobic. Hydrophilic ceramides hydrate and lock in moisture under the skin, while hydrophobic ceramides create an occlusive layer to prevent water loss, and together, they effectively hydrate and repair the skin.
