The invention discloses a preparation method and product of a skin co-penetration carrier of ceramide and fat-soluble active substance, including ceramide, fat-soluble active substance, phospholipid, cholesterol, fatty acid, phytosphingosine, liquid lipid, solid lipid substances, polyols and water. The carrier is positively charged, and the ternary permeation-promoting system can significantly increase the penetration of ceramides in the stratum corneum of the skin, exert its effects of enhancing skin hydration and improving the fluidity of stratum corneum lipids, and then promoting the lipid-soluble active substances in the carrier. Skin penetration to achieve the purpose of co-penetration. |
