The present invention provides a technology for delivering a ceramide across the horny layer to sufficiently exert the effects of the ceramide. Specifically, the present invention provides a skin external preparation comprising a ceramide, which enables sufficient delivery of a ceramide comprised in the skin external preparation across the horny layer to near the dermis when the skin preparation is applied on the skin surface. A skin external preparation of the present invention comprises a ceramide, an organically modified clay mineral, a diester of N-acylglutamic acid, and a phytosterol as essential components and in the form of water-in-oil emulsion. |
