I have used LCH machines for mosquito bites with great success. The ones with ceramic plates that can reach 51C. If one searches in the internet, there are many good comments for these machines from buyers. There is also this research:

Use these machines at least three times a day from the first signs of a cold sore. You can use them repeatedly but with 2 minutes intervals at least in order not to get burned. No more than 5 uses per hour. The burning sensation is for about 3-6 seconds.

Been dealing with this regularly for 30 years.. ended up with acetone dabbed on with earbuds.
Initially kept it on until the burns. Now I'm not sure if a lot of the scabbing that follows is due to the coldsore healing itself, or actual acetone burns.
Will keep using it. Maybe cautiously to avoid damage to surrounding areas, which may actually take longer to heal.

This is the only remedy that actually prevented the cold sores from going from stage one to the other stages of the blisters. Using acyclovir, I always had to go through stages 2 to 5.
Together with neem oil, it is good to supplement with L-Lysine and reduce sugar coffee and other arginine rich food (wheat for example). When going out in the sun use lips sunscreens, as long exposure to sun is likely contributing to outbreak triggers.

Dabbing colloidal copper on the cold sore stops the cold sore from ever breaking out.

My lip went down after a couple hours. I then poked the blister with a needle and got the fluid out. Next day it crusted over. Did the acetone all day again but maybe fewer times. Third day was just a scab. Did the acetone a few more times just in case. Now I'm just waiting for the scab to come off. I'm on the fourth day. It usually takes a week before it scabs over. I guess I'll be doing this from now on.

Many years ago in China, a local doctor gave me a vial of Bingpengsan (borneolum and borax), which is a white or pink powder. She told me to rinse my mouth three times a day with diluted hydrogen peroxide (4 parts water, 1 part hydrogen peroxide). After rinsing, I was to use the equivalent of a Q-tip to spread the Bingpengsan lightly on the cold sore. This must be done immediately when the cold sore just emerges.
Within a day the cold sore will dry up, but keep using the treatment. About day three, the cold sore will have turned into a scab and will fall off. I've kept the vial for more than 25 years and use it whenever I feel/see a cold sore emerge. It has never failed to eliminate the cold sore immediately. I'm not sure where or how to get this type of powder in the U.S., but my acupuncture doctor has provided to me a powdered preparation in capsules called Tianqi, which has the same effect on open wounds (like blisters, burns, scrapes, bed sores). Just take the the powder out of the capsule and sprinkle or spread it on the open sore (if it's a blister, just put the powder on it). The wound will dry up and scab over very, very quickly. I've never tried the Tianqi for cold sores, but it seems to have the same action as the Bingpengsan.

If one sore has emerged, then it goes away quickly - if it hasn’t then the L-Lysine makes it go away fast.
I keep a bottle of it in my vehicle, as we know those suckers can strike at any time & don’t wait until you have some on hand.
Reading through the posts, some take it daily. I heard you should ONLY take it when needed and prolonged use is not good for you, other posts say it can affect the liver-so be careful out there, do your research, and if confirmed, only take for a few days to a week.

Miracle of miracles, the acetone worked! Several times of the day, I would press a q-tip dipped in 100% acetone onto the area until it stung and then removed it. The cold sore never even got to the tingle phase. By day two my lip was slightly swollen but only about a third of what it normally would have been. By day three it was 10% swollen with a simple scab that could be covered with lipstick. No blisters even. Unbelievable. A week later, the small scab is still there, but the sore is clearly receding to nothing.
Where has this been my whole life?! The acetone must just kill the virus! Thank you all for sharing your experience with this amazing remedy! So helpful.

I usually drink coffee but like to have tea sometimes.
I had a cold sore a few weeks ago and didn't have lemongrass that I usually use on them.
After having a few sips of black tea I realised the swelling feeling was gone.. so I put some directly on the sore. It basically stopped the progression of the coldsore and started healing.
I tried it again today after having another one pop up, it didn't disappoint and is healing.
Apparently the tannins in the tea kill off the coldsore virus.

I think acetone must be used at the first signs and would be very effective but not once the skin has broken.

When one of these appears in the mouth - what has worked for me is eating a good quality raw kale greens - or take Lysine tablets. it works.

Panicking I scoured the internet and saw Cheri's post from 2021. I tried it and put acetone on each one with a q-tip for about 20 seconds each and 1 DAY LATER they had all scabbed over!!
This would have been at least a week or more without this remedy! Thank you!!

Woke up the next morning and it wasn't swollen anymore. Already formed scabs and started healing. Few days later my lip was back to normal. For the healing, I put Abreva on. I typically get blisters from the sun. Haven't had any in a couple months. Might be my new go to as Apple Cider Vinegar sucks. Ketchup is everywhere! Won't hurt to try. Says to use it at the tingle stage to prevent them too.

Get a fresh lemongrass stalk, peel one of the layers off and use a spoon..I usually have the spoon up right while I scrape the inside lemongrass layer using my thumb to hold it down and get the juice on the spoon that way.. then put it on the cold sore with my finger...
The 1st couple of times I just put the layer on a plate and used the spoon and pressed it down to get the juice on the back of the spoon and used the spoon directly on the cold sore so I didn't have to wash my hands after.. or fold the layer in half and use the juices that produce at the fold directly to the cold sore..
1st time I used it, it was at the tingle stage.. within the hour of it tingling I applied the lemongrass juice just the once and the tingle stopped instantly. It was around midday/ early afternoon that I applied it.
The next morning I felt the tingle again.. I could see slight redness however no blister so I quickly put some more on and immediately stopped tingling and started healing after that.. no blister. No more applying. It just didn't progress into a cold sore and it healed from that point on.
2nd time it had just started to rise and was about to form a blister. I had no lemongrass on hand so went to the shops and grabbed some.I applied it that afternoon and before bed. The next day no tingling and it was healing. I didn't need to apply anymore.
So it would seem that 2 applications are necessary.
4th or 5th time I had kept the lemongrass in the freezer.. to my dismay, it did not work. It took the tingle out a little which I felt I needed to keep applying it.. soo I did all day and the next day.. but it continued into a blister.. I got some fresh lemongrass the next day and it worked. Immediately stopping its progress.
So the lemongrass has to be fresh.
I've tried all the creams.. they aren't really great.. at 1st they helped the itchiness etc but never stopped the blisters...and after a while don't do anything at all..
I've tried peppermint extract.. as I had read good things.. but this didn't help really.. made it less itchy but didn't help the blisters.. same as toothpaste.. it stops the itch but it burns the skin and makes the area bigger.
Lemongrass by far is the best thing I've tried. Knocks it out.
