Abstract:
In a cosmetic composition according to the present invention, a coating membrane with a multilayer lamella structure is formed on the outside of ceramide particles by using phytosphingosine, and therefore, the cosmetic composition is stably present without ceramide precipitation even in formulations with low viscosity as well as high viscosity although the particles contain a high content of ceramide, and a cosmetic composition showing an excellent skin barrier recovery effect can be provided.
