My skin tags (mostly on my arms) disappeared when I lost 90 lbs in weight around twelve years ago. I've since put about 20 lbs back on and one or two have reappeared.

I had a funny growth on my left ear which made lying on my left painful. About three years ago the dermatology consultant at Donny hospital sprayed it with that freezing stuff, and it disappeared in about a fortnight. It's coming back again now, though not yet as bad as it was.
