Ceramides are a class of amide compounds formed by dehydration of long-chain fatty acids and amino groups of sphingosine. There are mainly ceramide phosphatidylcholine and ceramide phosphatidylethanolamine. Phospholipids are the main components of the cell membrane, and 40% to 50% of sebum in the stratum corneum is composed of ceramide. Ceramide is the main part of the intercellular matrix and plays an important role in maintaining the balance of water in the stratum corneum. Ceramide has strong ability to bind water molecules and maintains skin moisture by forming a network structure in the stratum corneum. Therefore, ceramide has a moisturizing effect on the skin.
Ceramides (Cers) are present in all eukaryotic cells and play an important regulatory role in cell differentiation, proliferation, apoptosis, aging, and other life activities. Ceramide, as the main component of intercellular lipids in the skin stratum corneum, not only acts as a second messenger molecule in the sphingomyelin pathway, but also plays an important role in the formation process of the epidermal stratum corneum, maintaining skin barrier, moisturizing, anti-aging, whitening, and disease treatment.
The use of skin activating essence cosmetics containing neurophthalamide can strengthen the anti-aging function of the skin, keep the skin elastic, smooth and delicate, and reduce the formation of facial wrinkles.
Ceramides play a wide and important role in the growth, proliferation, differentiation, apoptosis, and damage processes of cells.
Many health foods can be developed by utilizing the physiological functions of ceramides. This type of function has effects such as inhibiting blood pressure rise, activating immunity, inhibiting lipase activity, and inhibiting cancer cell proliferation.
