The present invention relates to a protein hydrolyzate containing a protein hydrolyzate of larvae of Protaetia brevitarsis hydrolyzed by any one or more of flavorzyme or Alcalase, which is a proteolytic enzyme, as an active ingredient. The present invention relates to a composition for improving elasticity, and more particularly, the protein hydrolyzate contains a peptide of 0.11 kDa or more and less than 1 kDa, thereby increasing the expression of PPAR-γ and C/EBP α, or adipocyte differentiation marker gene. It was confirmed that wrinkle prevention, improvement, and therapeutic efficacy were excellent by promoting adipocyte differentiation by increasing the mRNA expression of In addition, the composition of the present invention can be utilized as a composition for wound healing and hair loss improvement or hair growth promotion composition. |
