zit's, pimples, acne, fever bilisters, it clears zit's pimples, acne within a few hours to one whole day. it clears fever blisters like this: when ya feel one coming on apply asap, it wont even evolve into a fever blister, it ya have one already there it will take 2-3 days but you have to apply every hour until bam its gone a hell of alot faster than a month even longer and no scarring but that depends on how long you have let your blister go before youeven thought of buying the stuff! but existing or one coming on its the best stuff on the market! thats why its expensive!

Abreve shortens the length of time for a cold sore and offers great relief

The only one available in the US that works. In UK there are other brands that are cheaper & work.

I haven't had frequent coldsores (5-6 times a year) like a lot of people, but I received my first one as a kid..then twice as a teen (14-16) and now this is my second time this year at 22.I have to say it is completely EMBARASSING to have a cold sore especially if you are in college like me and work in a place where people are constantly in your face.I was working when I felt that the lower corner of my lip was bruising..I thought maybe I had cut it while eating some chips. But after work when I looked in my car mirror...I saw two small pimply white dotted bumps beginning to cluster up on me. So I came here and read the reviews and Unlike most of the people here, I have no idea when I'm going to get one..my mouth does not tingle like everyone elses. Therefore when most of the reveiwers said abreva wasnt as good if your sore broke the skin i instantly became deterred. However, I had no other choices so I picked it up anyway. And Might I add its [$].I began rubbing abreva on every 1-2 hours (a very small amount) and icing the sore in between (I hear it helps too) and needless to say..my sore went away in maybe 3 days. I couldnt believe it..the last coldsore I had lasted almost 2 weeks and it looked horrible and deformed I even missed classes because of it and wore a bandaid. (It sat off to the side of my lip)I'd like to add that during the three days..my sore didnt get any worse then what it was when I found it..it did not form into a monster it just blended with my skin until it began to heal..I even went out completely unphased by it. NO ONE noticed it...I am so a believer of abreva now, and if you find yourself in the boat I was in..just make sure you apply often (to be safe) and ice it 3 times a day as well..(until the icecube melts). Abreva is great and even thought its small it helped me greatly however, I think icing it made it work even better.4 out of 5 because it did cost me [$] and the tube is really small.

Oh my gosh, how embarrassing to have a cold sore. With this product, I soon as I feel one coming, I can get rid of it with this product before the sore even really surfaces. If you don't catch it in time, it will be gone within a couple of days with this product none the less. I highly recommend it. Some take Lysine in addition for a bad breakout, which is also a really good preventative when under stress when outbreaks show up and to get rid of cold sores quickly. Hope this helps someone else out there too.

I've used this for about a year to help with cold sores. It works really well if you catch your cold sore just as it is appearing, or starting to appear (first 12 hours or so). If you try applying it after the cold sore has already formed, it doesn't give you much benefit at all. It is very convenient, but a little expensive. That said, I always keep one tube around.

Best treatment for cold sores. works wonders for me. i always keep an extra tube at home so that i can apply at the very beginning of symptoms.

Everyone responds differently to a product. For me, Abreva did not work on my cold sores. I did not notice any fast healing. I applied the cream a couple of times a day and did not see any results. The cold sore lasted the same amount of time if I had not applied Abreva. I will probably purchase again, it did not make anything worse.

Abreva stops fever blisters and at the very least makes them smaller and disappear sooner.

Abreva is very expensive, but it does seem to get rid of cold sores more quickly than letting nature take its course. It's best to start using it immediately. The biggest problem besides the cost is the packaging. I've tried both the pump and the squeeze tube. The pump is hard to control, so you invariably get more than you really need for each application. the tube makes that easier, but be careful when you first puncture it to open it -- a big bunch squirted out the minute it opened and there's no way to put it back in. As much as this stuff costs, you don't want to waste a single dab -- and that's almost impossible to avoid. Still, it works so well I'll keep buying it until I find another product that works as well but is packaged to be more user-friendly.
