摘　　要：Photoprotection effect of the hyaluronic acid and ectoine composition was studied by evaluated its effects on inhibiting oxidative stress and MMP-1 production,ROS scavenging ability and promoting collagen synthesis in skin cells under blue light irradiation.The result show that the composition is non-toxic to keratinocytes within a concentration of 5%.And the sample can significantly inhibit the increase of reactive oxygen species(ROS)caused by blue light irradiation at a concentration of 2%,and can also repaire the damaged skin by scavenge oxygen free radicals.At the same time,the composition can inhibit the increase of MMP-1 caused by blue light irradiation,so as to have the effect of inhibiting the decomposition of collagen and promoting the secretion of Collagen I.
