سيراميد

Ceramide is a natural grease found in plants and animals, It exists in all eukaryotic cells, playing an important role in regulating life activities such as cell birth, cell division, growth, and aging.

Professionally speaking, it's a type of amide compound formed by dehydration of fatty acids and the amino group of sphingosine.

Ceramide also is the main component of intercellular lipids in the outer skin layer, about 40% ل 50% of the sebum in the stratum corneum is composed of ceramide. It not only has a strong ability to associate with water molecules therefore maintains skin moisture. But also promotes the formation of outer skin, which has the functions of maintaining skin barrier, moisturizing, anti-aging, whitening, and disease treatment.

For easy understanding, imagine that our outer skin layer is a wall, epidermal cells are the bricks, then ceramides are the cement between the bricks. If there is a lack of cement, guess what will happen to the wall? Light, air, dust, and bugs even mice will sneak in. Same reason for the skin. If the skin lacks ceramide, light, dust, and bacteria will easily invade in. Finally, the skin will gradually become unhealthy.
