The present invention relates to: a method for preparing a stem cell culture solution which contains growth factors and cytokines and is obtained by culturing, in a serum-free medium, mesenchymal stem cells cultured in a medium containing human platelet lysates (hPLs); and a cosmetic composition using the stem cell culture solution. When the method for preparing a mesenchymal stem cell culture solution obtained from mesenchymal stem cells cultured in an hPL-containing medium is used, it is possible to obtain a mesenchymal stem cell culture solution which has a higher amount of cytokines and growth factors than that of a mesenchymal stem cell culture solution obtained from mesenchymal stem cells cultured in an FBS-containing medium, and has excellent efficacy in the promotion of human dermal fibroblast proliferation, collagen synthesis, elastin synthesis, inhibition of melanin synthesis, and hair growth. The mesenchymal stem cell culture solution can be used to produce cosmetics having effects of skin regeneration, wrinkle improvement, skin elasticity enhancement, skin whitening, and hair growth, and thus can be widely used in the cosmetic field and the pharmaceutical industry.
