polysporin cold sore patch's work, they protect from passing a cold sore to someone else , as well as it hides it from people being able to see it.
The one and only thing I dislike is if you have to somewhat have the patch touching the inside of the lip it won't stick or become unstuck because of your mouth being wet. But it still us a great product

I break out in cold sores often, whether it be from stress, my period, the weather etc, I tend to breakout multiple times a year, 2015 was especially bad and I can honestly say these patches are a life saver. Nobody likes to have their lips breakout and I always feel like people are looking at them when I have them. These patches cut healing time in about half. Every other product I have tried still has a healing time of roughly 2 weeks, where as these patches heal in about a week or less. I also find these patches help skip the phase of the blister swelling to the size of your lip then breaking, and just cuts to the healing then scabbing if you don't leave it on the whole time. I always have patches in my purse and always buy more when I run out so they are always on hand.

I have tried a very large lot of products and home remedies for cold sores so I was very curious about this one when it came out.
Although it did cover the cold sore and made it easier for eating and applying lip stick, I found the product came off very easy and when you removed it, it tore of some of the healed sore and left it bleeding. This product never worked first or last and I ended up having the cold sore much longer then normal.

I get cold sores alot and i used polysporin cold sore patch and it was gone in a few days and now iget less cold sores also. This would be the product to buy

My family all uses this product all the time,, works great! Usually within 3 days, cold sore is pretty much gone, Love it,

This product works great. I have never had a cold sore before and I didn't know what I could do to heal it. My pharmacist recommended this to me.

I had such high hopes for this product and the concept in general but this did not work for me. When I changed the patch it ripped my skin off making it bleed and it took much longer to heal. I won't buy again.

A bit expensive (over $1.00 per patch - 15 patches for $18.99) but works fairly well. It covers up cold sores to stop it from spreading further, helps numb the pain, and sucks out the infection over time. Make sure to clean often and change the patch several times a day. No matter what treatment you use, it takes time.

I have used those and I found they really worked...was pleased with the product but didn't like the price...
