The present application provides a glabridin composition with high skin permeability and a preparation method and use thereof, belonging to the field of cosmetics. The glabridin composition is prepared from an S1 phase, an S2 phase and an S3 phase, in which the S1 phase consists of an oil and glabridin, the S2 phase is prepared from 3-o-ethyl ascorbic acid, an anionic surfactant, a nonionic surfactant, a polyol and water, and the S3 phase is water. The glabridin composition is prepared by conventional emulsifying equipment, and has low preparation cost, and simple operation process. The composition has good skin permeability, and has good state stability, good content stability, good pH stability and high mildness under high temperature and low temperature conditions, thus having unexpected technical effects.
