it seems that every year around this time, I develop a skin irritation around ether the corners of my mouth or around the sides & underneath my nose. This time it is around both corners of my mouth. One side is worse than the other. It is not bumpy, but more raised, red, scaly patches. After washing my face the scaly skin peels. At times it seems to get better, but I don't belive that it is. It came on all of a sudden, without any warning. What is this and how can I treat it? It is very embarassing.
