Abstract: The present invention relates to a non-biological skin model comprising a polymeric material reproducing skin surface topography that is coated with a lipid composition, wherein the polymeric material is a material having a surface free energy (?) of between 14 and 60 mJ/m2, wherein the lipid composition comprises from 14% to 60% of triglycerides, from 2% to 40% of free fatty acids, from 4% to 30% of wax esters, from 3% to 20% of squalene, and from 1% to 10% of cholesterol, and wherein the surface concentration of the lipid composition on the polymeric material is between 500 ?g/cm2 and 2500 ?g/cm2. The present invention also relates to a method for preparing said non-biological skin model and to its use for evaluating cosmetic products performance or for evaluating the effect of pollution on skin surface properties.
