I think I looked through all those liquid bandaid products and they all say to keep away from the mouth. Now the Compeed cold sore patch JasmanUK did is much more intriguing to me.

Unfortunately, the product isn't sold in the US as far as I can find--the only thing with the same hydrocolloid material is for blisters doesn't stay on the lip at all and has an adhesive that will just rip the frail lip skin off (I tried).

So anyone else in the UK with some money to spare who wants to try the Compeed brand patches I think it's a great idea with some positive results already.
