description A skin external composition comprising a cathepsin G inhibitor is provided to prevent an adhesion protein from being degraded by intrinsic aging and photo-aging, reduce the production of metalloproteinase and inhibit the activity of metalloproteinase, thereby being more potent anti-aging substance than existing anti-aging substances. A method for screening anti-aging materials is provided to develop the anti-aging materials which effectively inhibit the quantitative and qualitative increase of metalloproteinase, resulting from the degradation of an adhesion protein by cathepsin G in skin cells without direct UV irradiation. A skin external composition for preventing skin aging comprises 0.01-10 wt% a cathepsin G inhibitor as an effective ingredient, wherein the cathepsin G inhibitor is at least one selected from the group consisting of compounds represented by formulae(1) to (4). The composition is formulated into skin lotion, astringent lotion, milk lotion, nourishing cream, essence, massage cream, eye cream, pack, body lotion, body cream, body oil or body essence. A method for screening an anti-aging material comprises the steps of: (a) adding an anti-aging candidate material to a substrate in the presence of cathepsin G enzyme; and (b) measuring the inhibition of activity of the cathepsin G enzyme. Further, the measure of the inhibition of activity of the cathepsin G enzyme is performed by measuring a concentration of a produced metalloprotease.
