Ceramide liquid crystal composition and Preparation Method Thereof |
| abstract |
The present invention relates to a method for stabilizing vitamin C liposoluble derivatives used for restoring skin damage caused by exposure to near-infrared rays or ultraviolet rays, and relates to a liquid crystal composition together with ceramides and a method for producing the same. According to the present invention, a vitamin C derivative having an anti-aging effect and a wrinkle-reducing effect but having poor stability and skin-conveying ability can be stabilized through a ceramide liquid crystal having a lamellar structure and the absorption can be improved. In addition, when the vitamin C derivative is stabilized in liquid crystal form and provided as a cosmetic formulation, the stability against oxidation is enhanced and the loss of activity due to oxidation is greatly reduced as compared with the case where the vitamin C derivative is simply mixed without liquid crystallization. |
