Lipid layer forming composition for administration onto a surface of a living organism

A lipid layer forming composition comprises a volatile silicone oil of a boiling point above 180 DEG C, a polar lipid, optionally a C2 - C4 aliphatic alcohol, optionally a pharmacologically or cosmetically active agent or a protective agent. The lipid layer forming composition can be applied to a biological surface by spraying, dipping or brushing to form a stable polar lipid layer on the surface.
