The purpose of this research was to investigate the pharmacological effects of preparations containing beta-carotene, $Beautycarotene^{TM}$. $Beautycarotene^{TM}$ increased the collagen synthesis in CCD-986sk cells, DPPH radical scavenging activity and tyrosinase inhibitory activity in vitro system. In addition, it enhanced the viability of murine thymocytes and the population of splenic $CD4^+$ cells. Also, it increased the phagocytic activity of murine peritoneal macrophages. These results indicate that $Beautycarotene^{TM}$ can have a protective effect of skin via the diverse action, such as the stimulatory action of collagen synthesis, antioxidative action, tyrosinase inhibitory action and immune regulatory action.
