Hi Lydia and Lynn, thanks for your responses

I have had this on and off for a while - I think I first noticed it around the time my daughter was born (fifteen years ago...). It was around the same time I moved from CT to VT though, from suburbs to country, from city water to well, so who knows, there could be other factors involved. Sometimes I notice that it is gone, and I can't figure out what helped! What strength cortisone is good for the face? I'm thinking as low as I can get, right?
Thanks again!
