Claim Text:
1. A method of inhibiting aging of skin using a stem cell conditioned medium, comprising: applying at least 10.0 wt. % of the stem cell conditioned medium to the skin of a subject in need thereof to inhibit oxidative stress and aging of the skin, wherein the stem cell conditioned medium scavenges free radicals and increases the survival rate of skin cells under oxidative stress; and wherein said stem cell conditioned medium is produced by: (a) culturing human Wharton's jelly mesenchymal stem cells in a cell culture dish containing a complete growth medium, wherein the complete growth medium includes α-MEM, fetal bovine serum, and human-basic fibroblast growth factors; and (b) sub-culturing the human Wharton's jelly mesenchymal stem cells in the complete growth medium at least three times and transferring the human Wharton's jelly mesenchymal stem cells to a basal medium to obtain said stem cell conditioned medium, wherein the basal medium includes α-MEM and human-basic fibroblast growth factors.
