N.B.
Not sure..but I have some strange blotchiness this time of year on my cheeks as well and I have determined it is likely wind burn from being outside. I went to an outdoor parade over the weekend, but other than that I am just in and out to run errands, but it seems the older I get, the more this happens. Could this be the case? Is it cold where you live?
Just a thought...good luck!
