These patches are expensive, but worth every penny. if used at the onset, your cold sore should be healed within days. Amazing product!

I don't really get cold sores but my friend does a lot ... she tried this once and never again .. it was to pricey and didn't work at all, it gave her a bit more soreness to it.

My husband uses these when he gets a cold sore and he likes them and I buy them for him when he needs them.

It is a great product as long as you have patience. It's not worth the price of it but it still does work.

Not really works on me,a bit pricey !

this cold sore patch really works. it said that itll take a few weeks to work but it took only a couple of days to heal.

A great product, although a little pricey. My daughter loves it.

Although these are a bit pricey they work very well. I have tried just about every product out there and Poly is by far the most effective!!!

Great product! Used for years and will continue to!

I love the produc, verry efficasity.
