The present invention provides an oil-based humectant which is characterized by being composed of an esterified product of a component A and a component B, or an esterified product of a component A, a component B and a component C, and which is also characterized in that: the esterified product has a hydroxyl value of 0-180 mgKOH/g; and the mass ratio of the fatty acid residues derived from the component B to the fatty acid residues derived from the component C in the fatty acid residues constituting the esterified product of the component A, the component B and the component C is from 99.9:0.1 to 25:75. The present invention also provides a composition for external application to the skin, which contains this oil-based humectant. Component A: a polyglycerol which has an average degree of polymerization of 2-10 as calculated from the hydroxyl value Component B: one or more fatty acids which are selected from among linear saturated fatty acids having 6-10 carbon atoms Component C: one or more fatty acids which are selected from among fatty acids having 6-28 carbon atoms (excluding the component B)
