The present invention has as an object to provide a composition for external use on skin whose percutaneous absorption of an active component is increased, whereby a large amount of the active component can be delivered into the skin. By employing diglycerol and a low molecular weight betaine together, a percutaneous absorption accelerator excellent in permeability of an active component is provided. According to the percutaneous absorption accelerator of the present invention, the accelerated percutaneous absorption amount of an active component is greatly increased, whereby an effect which the active component essentially possesses is sufficiently exhibited.
