COMPOSITION FOR PREVENTING OR TREATING SKIN PHOTOAGING COMPRISING EXTRACTS OF ALPINIA OFFICINARUM HANCE

摘要

The present invention relates to a composition which can be used for preventing or treating skin photo-aging due to ultraviolet rays, comprising an extract of Alpinia officinarum Hance as an effective ingredient. According to the present invention, it has been confirmed that a hot water extract of Alpinia officinarum Hance has an effect of increasing an expression of procollagen synthesis gene (procollagen type-1) in UVB-treated mouse skin fibroblasts (NIH 3T3 cells) and increasing an expression of extracellular matrix (ECM) degrading enzyme (MMP-1), and is capable of inhibiting an expression of inflammatory cytokines (IL-6, IL-8) increased by UVB ray treatment. According to the present invention, the composition containing the hot water extract of Alpinia officinarum Hance as an effective ingredient can be used to prevent or treat photoaging caused by ultraviolet rays.
