HYALURONIDASE INHIBITOR

PURPOSE:To provide the subject inhibitor having a high safety and capable of being continuously used for a long period, by containing pyridoxine, pyridoxamine, pyridoxal or a salt thereof as an active ingredient. CONSTITUTION:The inhibitor contains pyridoxine, pyridoxamine, pyridoxal or a salt thereof (e.g, a hydrochloride salt or phosphate salt) as an active ingredient. The compounds all are soluble in water and therefore readily compounded with aqueous solutions. Since the compounds have a medium wavelength UV ray-absorbing action, the compounds have an effect for preventing the decomposition of other components caused by the UV rays.
