  ABSTRACT: Natural killer (NK) cell is a type of immune cell and is known to be particularly responsible for innate immunity such as anti-cancer immunity, defense mechanisms against infections, and secretion of various cytokines and chemokines for increasing recruitment of other immune cells. In this study, we investigated the potentials of NK-enriched lymphocytes (NKEL) conditioned media (CM) on skin care for cosmeceutical compositions. Various cytokines of NKEL CM can improve wound healing through epithelial-mesenchymal transition (EMT) by increasing KLKs (kallikreins) and reduce metalloproteinase (MMP)-1 and MMP-2 to inhibit wrinkle formation. Our results suggest that NKEL CM which has various cytokines promotes up-regulation of cell migration and KLKs and down-regulation of MMP-1 and MMP-2 by stimulating HaCaT keratinocytes migration. Therefore, NKEL CM can be used as a cosmetic composition that can play a role in skin regeneration and anti-aging.
