PROBLEM TO BE SOLVED: To provide a thyrosinase activity inhibitory composition suitably applicable as a cosmetic whitening and a skin-beautifying composition, inhibiting the thyrosinase activity sufficiently even by a small amount since it exhibits an excellent synergistic effect, and also having high safety to a living body. SOLUTION: The effect of the thyrosinase activity inhibitory composition is achieved by using anα-lipoic acid and a reduced form glutathione at the same time preferably at (100:0.01 to 5) weight ratio.
