Claim:
1. A multi-lamellar emulsion composition for skin external application, which comprises: 15-22 wt % of lipid components comprising, based on the total weight of the composition, 3-4 wt % of long-chain amide and sterol and 12-18 wt % of fatty acid and fatty alcohol; 6-10 wt % of an emulsifier based on the total weight of the composition; 12-18 wt % of oil based on the total weight of the composition; and a balance of purified water, wherein the ratio of the content of the long-chain amide to that of the sterol is 0.1-1.8:1 by weight, the ratio of the content of the lipid components to the emulsifier is 1.8-3.0:1 by weight, and the sum of the contents of the lipid components and the emulsifier is 21-32 wt % based on the total weight of the composition.
