Mine turned from chapped upper lip to a break out on the upper lip. I am currently putting coconut oil on it and it is getting better(it has been about 2days--just started putting coconut oil on it yesterday). It is not completely gone, but getting much better. I think I am one of the ones that over did the OP. I was oil pulling at 1st once in the morning and then once at night w/Sesame oil, then I increased it to two 20min swiches in the morning and at night. I also during one of my swiches used some coconut oil(which I now know is one of the more potent oils). So now I am swiching twice a day--morning and afternoon and will work my way to coconut oil later. I am glad the toxins are coming out, but I did not want to go out w/a break out all over my lip(by the way, I normally don't get cold sores or cancer sores--actually don't remember ever having them).
