The application of matrix metalloproteinase (MMP) inhibitors to the skin inhibits the degradation of proteins found in the skin including collagen, elastin, and other basement membrane and extracellular matrix protein. MMP inhibitors may be used in both cosmetic compositions and pharmaceutical compositions for application to skin. MMP inhibitors are formulated with a cosmetically suitable vehicle or pharmaceutically acceptable excipient for application to the skin as creams, lotions, ointments, solutions, face masks, etc. As cosmetics, the inventive MMP inhibitor compositions are applied to the skin to prevent or reduce the appearance of wrinkles, pigmentation changes, loss of elasticity, or other effects associated with aging or sun damage. As pharmaceuticals, the inventive MMP inhibitor compositions may also be applied to the skin to treat or prevent a skin disease (e.g., proliferative disease, inflammatory disease).
