Polar lipids essential for the proper functioning of the skin barrier. Their role is to avoid the excessive loss of water through the skin's stratum corneum. A decrease in ceramides present in the skin leads to dry skin. The choice of soaps used is decisive in their preservation. Synthesised ceramides can be added to an emollient cream. They can be extracted from various origins (plant, animal, synthetic) and can be used in moisturising creams. Their concentration must be always higher than 1%.
