All my life ive suffered with cold sores & tried all sorts of creams. Just recently though I discovered Virilite, a handy, battery driven, light gadget, that you hold over your cold sore for just 30 seconds, twice a day. The beauty being, it really works and within a couple of days too. Lloyds chemist stocks them, but theyre a bit pricey. I got mine on E-Bay for £23.00 & I"ve got to say, it was worth every penny.
