An emulsion which has an average particle diameter of 100 nm or smaller and comprises: (D) a polyglycerol/fatty acid ester which has an HLB of 13 or higher and in which the polyglycerol is one in which the average degree of polymerization is 8 to 12, the total content of the pentamer and hexamer is 50% by weight or higher, and the total content of the tetramer and lower polymers is less than 20% by weight, and the fatty acid residue is C14-22 hydrocarbon group; (E) a polyglycerol/fatty acid ester which has an HLB of 5 to 11 and in which the polyglycerol is one in which the average degree of polymerization is 2 to 12, the total content of the tetramer and lower polymers is 20% by weight or higher, each of (2/3)n components being contained in an amount of at least 5% by weight or more, where n (n is 2 or more) is taken to be an average degree of polymerization (when (2/3)n is not a natural number, (2/3)n is considered to be a lowest natural number greater than (2/3)n), and the fatty acid residue is a C14-22 hydrocarbon group; (F) a lecithin; and (G) an oily ingredient.
