Ceramides (pronounced ser-A-mid OR seramide) are a family of lipid molecules. A ceramide is composed of sphingosine and a fatty acid. Ceramides are found in high concentrations within the cell membrane of cells. They are one of the component lipids that make up sphingomyelin, one of the major lipids in the lipid bilayer. For years, it was assumed that ceramides and other sphingolipids found in the bilayer cell membrane were purely structural elements.This is now known to be not completely true. Ceramide can actually act as a signaling molecule. The most well-known functions of ceramides as cellular signals include regulating the differentiation, proliferation, programmed cell death (PCD), and apoptosis (Type I PCD) of cells.
1.Ceramide with slap-up facial cleanser, food additive and function food(Anti-Aging with skin) extender.
2.Ceramide is the most essential factor in maintaining normal stratum corneum integrity. Therefore,the topical supplement of ceramide repairs the damaged skin barrier leading to give skin soft feeling.
3.Clinical studies in dermatology have revealed that in many cases of dermatitis such as atopy, acne and psoriasis are associated with lower level of Ceramides in stratum corneum than normal skin.
