It's an old wives' remedy, but it seems to work for us – at least until the pharmacy opens. When you feel the telltale tingling of a coldsore erupting, stick an icecube straight on to the affected skin for a few seconds (make sure it's melted a little so it doesn't stick) and then dab with cologne – if you can't find any, perfume also seems to work, suggesting alcohol is the key factor. Don't do it too often, though, as it may stain the skin. Long-term it may be an idea to have a BioStick to hand. It's clinically proven, emitting a low-frequency red light that, without heating or burning, increases blood flow to the affected area, stimulating immune cells to help heal the blistering skin.
