I've always had rather oily skin, which I have come to be thankful for. Now it is oily and scaly. I've tried various exfoliating products, but it doesn't seem to help. Retin A (backed off to once a week) just makes it worse, but when my face does the all-the-skin-dies-and-sheds thing from it, it is still scaly underneath. Does anyone have any suggestions for me? I am on HRT.
