I had a 'make over' at Boots yesterday, i came away looking lovely but after a few hours i felt the familiar tingling of a coldsore (probably from the tester Lipstick or lip pencil) i couldn't go and get anything for it there and then as all the shops were shut.
I have woken up with a whopper of a coldsore 
Does anyone know which topical treatment is best for shortning them time before it goes away?
