I know you use/d Nizoral cream on your face and am wondering if you have tried Lotrimin Ultra?
According to Jeff's research azoles interfere with yeast growth but don't do much to kill existing yeast wheres allylamines kill live yeast. In my experience Butenafine (an allylamine available in Lotrimin Ultra) is more effective than Ketoconazole (an azole available in Nizoral cream). Unfortunately Butenafine is not available in Australia and although I import it via eBay, I mostly rely on Nizoral. Interestingly, Turbenafine is useless on my face but reasonably effective in my groin area. Perhaps because it's a different strain of Malassezia, or the biofilm is less entrenched?
I'm interested in your thoughts... Lotrimin Ultra is OTC in the US, perhaps you have been down this path already?
