PROBLEM TO BE SOLVED: To provide a more highly active epidermal keratinocyte-activating agent than conventional activating agents, and to provide an external preparation for skin, having effects such as not only a skin somberness-improving effect, a bleaching effect and a skin texture-improving effect, but also an acne, rash-improving effect, which have not been obtained by conventional epidermal keratinocyte-activating agents. SOLUTION: The epidermal keratinocyte-activating agent includes a Carex humilis extract as an active ingredient. The external preparation for skin contains a Carex humilis extract in an amount of 0.0001 to 5 mass% as a dry residue, and further ascorbic acid or a derivative thereof in an amount of 0.0001 to 5 mass%.
