<P>PROBLEM TO BE SOLVED: To provide a plurality of MMP-inhibiting ingredients useful for inhibiting the ageing of skins. <P>SOLUTION: A matrix metalloprotease (MMP) inhibitor comprising the extract of Mallotus japonicus Mueller-Arg is added to compositions such as foods or cosmetics. The matrix metalloprotease inhibitors inhibit at least MMP1 and MMP9. The inhibition activity preferably exhibits an inhibition rate of ≥40% for either of MMP 1 and MMP9 in a 153 mU/μg (enzyme activity/plant extract) solution. <P>COPYRIGHT: (C)2009,JPO&INPIT |
