This 100% works. I have had cold sores all my life and I have used hydrogen peroxide and it is already dried out after 30 minutes. It is even better if u take a Q-tip dip it first in rubbing alcohol, then non- acetone nail polish remover then hydrogen peroxide. It burns so bad but its works so fast.!!

Last night a cold sore began to develop on my lip. I read on Earth Clinic to use hydrogen peroxide. I used cotton swabs and applied the peroxide to my lip. I did this using 5 separate swabs over a one hour period. I noticed immediate results within that hour. This morning I did the same and just did it again when I got home from work. The cold sore seems to be in its final stages and should be gone by tomorrow. I have used Abreva and saw the same results over 4-5 days. Peroxide worked for me and did so a lot faster.

Last Monday I had a cold sore outbreak in my upper lip (I started feeling the tingly sensation) , so immediately I looked for remedies in this website and I opted to use the Hydrogen Peroxide. Let me tell you it is a wonderful remedy for cold sore, by wednesday the cold sore was completely dry and it got never bigger than half size of a lentil bean. I had outbreaks before (usually when I am stressed) and it was a nightmare, the cold sore lasted for weeks ( I am not kidding) and it got as big as half of my upper lip. The treatment is extremely easy and cheap: damp a q-tip or cotton swab with the HP and apply to the area as many times as you can. i did it every 3 hours. Thanks earth clinic for such helpful information

First of all I would like to thank all of you who've shared your experiences and comments. Last Thursday night I felt some tingling around my mouth so I decided to go and get some Abreva, (silly me). I went to bed hoping it would not get one. The next morning I woke up with some small blisters on the top corner of my lip, (I had to call in sicked). By Friday afternoon the blisters had spread to my side of my mouth and it was now almost now the size of a quarter. This was the first time I had a sore that big. I was desperate and didn't know what to do. I could not show up to work on monday with a sore that big.

That's when I decided to do some internet research and I ran into this site! I read on some of your Hydrogen peroxide success stories and decided to try it. I had my wife go to the store and get a small bottle of it. I poked the blisters with a needle and then held a cotton ball soaked in Peroxide for as long as I could. I then, covered the soar with a ___ ( you can find this at you local pharmacy) this is a gel. The gel will harden and won't let the soar get any air. (the virus can't continue to grow without air). After a few hours I carefully remove the gel by rubbing peroxide on it. I repeated this process every 3 to 4 hours throughout the day. Did the same thing all day Saturday. By Sunday night, All I had was a scab. I put some chap stick on the hard scab to make it soft and remove it. Monday morning, I used some on my wife's make up to cover the redness of my skin. You could hardly tell I had something there. This is the quickest I've been able to get rid of a cold sore! Thanks to you all!!

I had never gotten cold sores before and this was the first time. It was horrible i had 3 HUGE cold sores on and around my lips. i waited 2 weeks and they didn't go away. i used pills and creams but nothing worked. I read here to use hydrogen peroxide and i figured what could i lose i already look horrible and i had 1 day befoe i was leaving to europe for 2 weeks. basically it works wonders! i had yellow puss dried up for about 5 days and it hadn't fallen off yet. the HP dissolved the dried puss and made it easier for me to pick off. some of the sores were still open so i put the hydrogen peroxide on( it burned like nothing else) it didn't puss over again it just dried out. now i have red skin but thats it. i can at least go out in public now

Hydrogen Peroxide cleared up my cold sore in 48 hours. I was and AM sick of paying for Abreva, etc...when it takes over a week to do anything at all. I never suffered from cold sores until the age of 22, and since then they have been directly related to the change in my hormones prior to getting my period. So, from 22 until now (almost 3 years), I've almost consistently had to deal with the annoyance/pain/discomfort of them. So, in a desperate search for a better answer, I came to your website (which has helped me a lot in the past), and 48 hours later I'm 90% cleared up! It's amazing, it went from appearing, to drying, to scabbing, to healing in no time at all. Thanks so much everyone for your input!

Using peroxide on gential herpes at the sign of itching is a sure way of stopping the itch and speeding up the healing process. Have used it and it does work. Must try the other remedies I have read about.

I have used peroxide for the last 3 years. Before that my doctor gave me this cream to put on but it didn't work. And abreva never worked for me either. And a family friend told me that she uses a needle to pop the little blisters, if its just forming and there are no little blisters visible, then she just poked holes in it, as much as she could stand, then she would use a q tip and dab on peroxide. It really works. I use the spray on peroxide myself. I prefer it, i just hold a Kleenex under the cold sore and spray it. And i keep spraying over and over until it stops foaming. And as for dieting to help, taking calcium pills will help. Also when its forming get some milk dip a cloth into it and press it against the cold sore, it should stop it from getting any bigger. The virus is always there, never gone, but it is contained by calcium like a big bubble, and when your stressed or sick, the walls of the bubble fade and weaken, then the virus gets out. So take lots of calcium! It does help. And any time i forget to take my pills, i get a damn cold sore!

I currently have an outbreak (the second one in 2 weeks) and I used peroxide on my second one after the first day. I didn't catch it in time but I'm finding that using the peroxide only 2 times has prevented it from really blistering and scabbing over too much. I popped the blister and drained it with a tissue and then used a qtip to dab it on a few times. It seems to take out the infection and dry it up faster. I'm going to continue applying peroxide every few hours and see how it works. I think if I'd have done this quicker, it wouldn't have blistered out quite so much. But it's less sightly than it would normally be.

Hydrogen Peroxide is my no fail solution to a cold sore. I always rub on my entire lip area with a soaked cotton ball at any sign of tingle, the tingle goes away. The moment I have a cold sore, I drench it in the peroxide and I normally start scabbing in a day or two. It is the best remedy to an outbreak I have found!!!
