COMPOSITIONS AND METHODS FOR USE AGAINST ACNE-INDUCED INFLAMMATION AND DERMAL MATRIX-DEGRADING ENYZMES

摘要

Acne-affected skin has been found to be accompanied by the presence of matri x- degrading enzymes such as MMPs and neutrophil elastase, induction of neutrophils, and a reduction in procollagen biosynthesis. This invention treats scarring and inflammation accompanying acne by administering, topical ly or systemically, at least one of (I) an inhibitor of the matrix degrading enzymes and (ii) a cytokine inhibitor that alleviates inflammation and thus also alleviate neutrophil infiltration. Alleviating the matrix degradation a nd renormalizing procollagen biosynthesis allows for reduced inflammation and better natural repair of acne-affected skin. Inhibiting cytokines alleviates induction of MMPs in resident skin cells, and also alleviates inflammation with its concommitant induction of neutrophils from the blood stream bringin g MMPs and elastase into the acne lesion. Dimishing the presence of matrix- degrading enzymes in the acne lesion reduces imperfect repair of the skin an d thus decreases scarring in acne-affected skin.
