CERAMIDES
INCI: Ceramides
What is Ceramides?
Ceramides are found in intracellular spaces of epidermal or stratum corneum. They are heterogeneous in structure and by changing an amide linkage or differences in chain length, fatty acid conjunction, hydroxylation, saturation, etc. different factors form a different ceramide altogether. They are essentially important in maintaining the intact structure and moisture permeability of the first layer of skin. Ceramides production decreases with age, and as a result dry and scaly skin as well as other aging skin problems like fine lines, wrinkles start showing up. Ceramides not only hydrates skin but they fill the space in stratum corneum, repairs it, some ceramides boost natural ceramides production. This helps skin gain its moisture and intact barrier back preventing future damage as well. There are few tens of ceramides, which form the stratum corneum of the skin, and amongst them, the following are frequently used ceramides.
