The present invention relates to a composition which contains chemokine, especially an interferon-inducible T-cell alpha chemoattractant (ITAC). In addition, the composition of the present invention decreases the genetic expression of factors associated with the production of melanic pigments in melanocytes, thereby exhibiting skin whitening effects as well, wherein the content of the ITAC is 0.0001-0.0005 wt% with respect to the total weight of the composition.본 발명은 케모카인, 특히 ITAC(interferon-inducible T-cell alpha chemoattractant; 인터페론 유도성 T 세포 알파 화학주성인자)를 함유함으로써 멜라닌 형성 세포에서 멜라닌 색소 생성 관련 인자의 유전자 발현을 감소시켜 피부 미백 효과를 가져올 수 있는 조성물에 관한 것이다.
