                        No idea what it is myself, but I am also 55, post-menopausal and take premarin.  I have red, dry, rough skin on my neck and nothing seems to help--lotions, cremes, diet...I can't figure it out, and my doc doesn't know either.  I wish you luck finding your answer.  I'll let you know if I find one.
