This was over 3 and half years ago and I'm not certain on the exact time frame, but I believe I was cured of EC in about 2-3 weeks because my peeling cycle was gone by then. The amount of time may be different for others trying this treatment, if it even improves their condition at all. If it doesn't, I still urge everyone who undergoes this specific treatment to report their results, because then we will have more concrete numbers on the success or failure of this treatment. So far I know of another member of this forum that is currently trying this method; He's had EC for over four years and reports that in two days of using saliva and palmer's cocoa butter, that "it does seem to be the best thing to ever happen to my lips. They seem softer and smooth during the day, and I usually start to see that white peeling border when they get wet (e.g. shower) but after I wipe it off it looks pretty good." I had similar experiences during my first two days, although my lips were noticebly less flakey.
