ive tried it, waste of time, doesnt work at all, lip cauterization is muchmore effective with a heat laser. Im getting another done in 3 weeks. I have a few areas that when normal, dry out along the border where the two lips touch. Once they dry out they dont heal properly and resemble the problem we have elsewhere on the lips. I get the area cauterized and it grows back healthy and normal for 3/4 of a year.
