I have used SE MH and HPS. Had a stint of squamous with MH. I know almost as much as most doctors when it comes to basal, squamous and fortunately no melanoma. though I may have had a tiny small dot of it on my shin. The stuff I use will kill it all in 24 hours. I had MOHs surgery for squamous when I was young. Got it on the shoulder from MH even though I always had shirts on. My stuff killed it in 24 hours and it took about a month to heal. Laugh it up. More than a few famous people have died from melanoma. I do not like MH at all.
