The present invention relates to a cell-free plant cell culture suspension supernatant having skin rejuvenation activity and / or wound healing activity. The present invention relates to a cell-free supernatant (conditioned medium) or a fraction of the cell-free supernatant that previously supported the growth of a dedifferentiated plant cell suspension medium, the cell-free supernatant or The fraction contains 4 to 300 amino acids in length, including peptides such as peptide plant growth factor and plant transcription factor, and has no cytoplasmic intracellular content and cell and cell wall by cell lysis. It relates to a fraction of the cell-free supernatant. The invention further relates to a cosmetic fraction that promotes the fraction of the supernatant and skin rejuvenation. [Selection] Figure 3a |
