  • Patent number: 10022317
    Abstract: The present specification relates to a composition comprising processed ginseng extract and processed green tea extract. Such a composition results in having a synergistic effect due to mixing of each processed extract, and is thus capable of promoting the production of procollagen and inhibiting the expression of collagenase. In addition, the composition of the present specification promotes the expression of filaggrin and is thus capable of strengthening a skin barrier function and inducing the differentiation of skin keratinocytes. Therefore, the composition of the present specification is capable of improving the general condition of skin, and can be effectively used as an external preparation for skin for preventing or improving xeroderma, atopic dermatitis, contact dermatitis, psoriasis, or the like that is caused by the imperfection of epidermal differentiation.
