I have been using MWF for a while ,about a month and a half , maybe once a week. Each time I have used it , my face has broken out in hives afterwards. I figured , maybe it was a soap I was using to wash my face did it. I have come to the conclusion today it must me the lanolin in it. I am pretty sad to learn of this because I enjoy using it so much. I had ordered an extra refill about a week ago , so that will be most likely going on BST when I redieve it.
