Nine long years ago, half a dozen small acne-like spots suddenly appeared on my chin, cheek and forehead. Never having had skin problems before, I went to my GP when they were still there weeks later. He diagnosed molluscum contagiosum, and said they were harmless but with no cure - they would disappear spontaneously within a few months or, at the very most, 2 years . So 4 years later, back I went still adorned with said spots and was told that sometimes it takes a little while longer, but they would definitely combust within the next year.... Needless to say, they didn't. Over the years I've done a lot of googling and attacked them with various lotions, potions and pills, to no effect. I've given up. There are worse things.
