Abstract
Acne-affected skin has been found to be accompanied by the presence of matrix-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, topically 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 and 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 bringing MMPs and elastase into the acne lesion. Diminishing the presence of matrix-degrading enzymes in the acne lesion reduces imperfect repair of the skin and thus decreases scarring in acne-affected skin.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
