I had several skin tags removed at the GP's surgery , they just snipped them off with sterile scissors , just a trace of blood that was stopped by applying cotton wool. No pain and over in a few minutes , no waiting for them to drop off or trying to tie cotton round them.
I just wish they sold liquid nitrogen over the counter as it does work. I had a dry patch (keratosis)on my nose removed by one spray of this at the doctors.
