Lipids in the surface layer of the skin which protect it from external factors and from loss of moisture from its deeper layers.
Damage in the surface layer causes loss of moisture from the deeper layers of the skin, which then becomes dry, taut and sensitive. The phospholipids in NiKEL products come from plant oils. They appear in an organised, liquid crystal form, arranged like roof tiles. Only in this form can they very quickly repair the damaged hydrolipidic barrier of the skin and in that way prevent the loss of moisture from its deeper layers.
