Abstract
The present invention relates to a composition for skin improvement containing at least one chemokine selected from the group consisting of B lymphocyte chemoattractant (BLC), also known as C-X-C motif ligand 13 (CXCL13), and thymus-expressed chemokine (TECK), also known as C-C motif ligand 25 (CCL25), as an active ingredient. Since the BLC (CXCL13) and TECK (CCL25) of the present invention increase the expression of proliferation marker Ki-67 and collagen IV, which are proteins concerning skin regeneration and skin elasticity, and exhibit excellent melanin-reducing and wound-healing effects and the ability to induce chemotaxis of keratinocytes, they can be applied in a cosmetic composition for skin improvement.
