Kelmar--in my case, while I had "erosion" on parts of my face, many parts were simply bright red. After healing it did not seem to matter whether I had cracks and flaking or just red skin, the AK's were effectively treated and eliminated. So if your dermotologist said you had enough, that is probably the case and you should not be "going backwards". FYI--I only used aquaphor post treatment to keep the skin moist and that seemed to work fine for me.
