Lipids in the surface layer of the skin which protect it from external factors and from loss of moisture from its deeper layers.
If the surface layer of the skin is damaged, the skin loses moisture and becomes dry, taut and sensitive. NiKEL products contain sphingolipids from plant oils in a organised, lyotropic liquid crystal form. Only in this form can they very quickly repair the damaged hydrolipidic barrier of the skin and protect the skin from irritation and loss of moisture from its deeper layers.
