Vegetal oils can be glycerol es-terified with free fatty acids such as stearic or palmitic acids. Such vegetal oils are sources of lipids that can become part of the intercellular lipid matrix and sebum, as they are similar to the natural lipid content produced by the skin. This process is called biomimetism. The molecules of these lipids can replace the damaged natural components of the skin, and thus restore a powerful intact barrier. With the help of the right cosmetic product application, in form of emollient agents, skin hydration can be modified and maintains the skin barrier effectively.
