Herpotherm Neo Cold Sore Treatment Device – Long Lasting and Reusable Heat Pen (Herpotherm neo)

I decided to delay my review until I was fairly sure it's effective. I stopped using any other preventative measures (except 3, see below). It's been nearly 5 months, I've had the tingling stage at least 50 times since then (no joke), and yet i'm completely sore-free. At first I thought this was a concidence, especially after a particularly bad tingling stage once. But so far so good!Cold sores have affected my mental health for a long time now. I'm guessing anyone who's on this page can related. I used to get them every 2 months, not always in the same spot. Especially when my immune system is down or i'm in a lot of stress. They hurt. I'm constantly aware of them. Wearing masks during the pandemic has been a godsend because I could leave the house without feeling so insecure about having them. As such, I've been doing everything in my power to fight them. I have tried every cream and sticker in the book.Not a single sore. Still can't believe it. This is huge for me.________________________________𝗛𝗲𝗿𝗲'𝘀 𝗵𝗼𝘄 𝗜'𝘃𝗲 𝗯𝗲𝗲𝗻 𝘂𝘀𝗶𝗻𝗴 𝗶𝘁:- The very moment a feel a slight tingle I use it. ASAP.- If the tingling is in more than one place, or in a large area. I use it more than once (letting it cool in between), and try to cover the tingling area.- If I feel it again, I use the device once more.- I tend to feel the tingling stage during bedtime, when this happens, I wake up and use it. One night, I had to use it 5 times (in like 7 hours).- TIME IS OF THE ESSENCE.... so I keep it next to my bed, in my pocket when i'm out, it's always nearby.________________________________𝗢𝘁𝗵𝗲𝗿 𝗽𝗿𝗲𝘃𝗲𝗻𝘁𝗮𝘁𝗶𝘃𝗲 𝗺𝗲𝗮𝘀𝘂𝗿𝗲𝘀:- I currently take L-lysine (1000 mg) daily. I've been doing this for ~2 years, I found that it helps in reducing cold sore frequency, as well as the damage caused by the cold sore (frequency sore area), and it helps healing quicker.- Lip with SPF when I'm out (especially when it's sunny or windy outside)________________________________I was reading a few of the reviews on here, and I have a few notes regarding how to use it:- 𝗕𝘂𝗿𝗻𝘀/scarring: If you're pressing it into your skin, you're doing it wrong, and chances are you're going to get burned/damage your skin!!!! The device is supposed to heat the only the EXTERNAL layers of skin to 50 degrees celsius for 3 seconds. This SHOULDNT burn the skin, the area will be a bit red and that pinkness will go away. Scarring occurs when the deeper layer of the skin, the dermis, is damaged.Remember that damaged skin is actually a good environment for cold sores to develop!!!!You shouldn't use it with creams/gels on. Make sure to keep the device clean. Simply hold the device against the skin directly, so that the plate is in full contact with the skin without pressing it into the skin.- 𝗜𝘁 𝗳𝗲𝗲𝗹𝘀 𝘁𝗼𝗼 𝗵𝗼𝘁/𝘂𝗻𝗽𝗹𝗲𝗮𝘀𝗮𝗻𝘁: Yes, it's definitely not too pleasant, but you get used to it at some point after which it's not too bad. If you're wondering what it feels: turn on the hot water tap (if your heater is at 49-50 degrees) with your fingertip under it, and allow it become hot and once it's reached maximum heat wait 2-3 seconds before moving your hand away. You can handle it. Imagine that on a smaller scale (5 mm in diameter) on/near your lip.The temperature does gradually go up making it more bearable. I suggest gripping something and/or watching something to distract yourself. Just give in to the heat, and it'll be over before you know it.Again, DO NOT push it into your skin. I suggest that you barely let it touch your skin the first time (so you know what you're getting into), but make sure to hold it for the 3 seconds. If I can bare it, you can bare it too, i'm sure of it. Rest assured that while it feels really hot, it's not damaging your skin.𝗜𝘁'𝘀 𝗻𝗼𝘁 𝘄𝗼𝗿𝗸𝗶𝗻𝗴/𝗶𝗻𝗲𝗳𝗳𝗲𝗰𝘁𝗶𝘃𝗲: it needs to be used AS SOON AS POSSIBLE for it to prevent the sore. Familiarise yourself with the tingling stage (prickly sensation, burns, itchiness, feeling of tightness, pain).If you're not sure whether that was actual tingling or a hair was tickling your lip, use it anyway. When in doubt, use it.it also needs to be used whenever you feel tingling. If you felt a tingle 40 minutes ago and used it, but then felt the tingle again, go ahead and use it again.You need to apply it at the site of the tingling. If you missed, allow the device to cool, and then apply it again.If it's in more than one area, use it on each area, allowing the device to cool between uses.Don't touch the skin after you apply it, let the skin cool down on it's own.𝗦𝗵𝗼𝗿𝘁 𝗯𝗮𝘁𝘁𝗲𝗿𝘆 𝗹𝗶𝗳𝗲: The battery that came with the device didn't last long (literally 2 weeks after I purchased it). Since then, I've changed the battery once, and it's still working well. Make sure that the you get a good battery and that the battery is placed the right direction. (I do hope that some day, they'd design a rechargable pen.)𝗖𝗢𝗡𝗖𝗟𝗨𝗦𝗜𝗢𝗡: Works perfectly at completely preventing cold sores if used at the right time and in the correct manner.

I've suffered with massive(I look like I've been hit with a baseball bat) on my lips every December for 35yrs now. Stress related. As well as different sizes on lips and in last 6 yrs on nostrils too, all year round. Either coz of bad health (Crohn's) or stress. I've used every type of cream on market ND prescription. All expensive for a tiny tube that doesn't last long ND no matter what stage I put it on it never stops the sores or the pain ND humiliation that goes with them as they look awful. I even tried those stupid patches once on my lip. So uncomfortable it was like hard plastic on my lip ND it didn't stick or be invisible as stated. So as I'd just started with the tingle again I thought I'd look for the creams but then I saw.. this product. New concept. I've nursed so n knew of diotherms in surgery but never this. I thought yes expensive but when you add up all the tubes you buy in a year.. ND heat kills virus. I took the leap. It came same day. I only use 2-3times a day for 2 days ND now only if tingles or swelling. It's on my nostrils so awkward place for first try. Yes it smarts a little but it's heat ND on sore skin so expect it. It's only for a few seconds ND it works. It actually works. I'm even going 6 buy my son 1. He gets 'normal' coldsore but he's a teen so hates them. He asked if it worked. So I said " can you see a sore"? "Nope!" Was his surprised answer. He loses the tiny tubes all the time too ND this is lipstick sized ND look. Easy to use. If you suffer regularly in a year... Try it. You know the tubes don't work so what do you have to lose other than those rotten sores. A lot quicker than creams or patches ND even on nostrils. The heat isn't that bad after first use after all we try not to burn ourselves but it's not hot enough to burn skin just sterilizer ND kill virus. Stop it spreading on you or to others. Thank you. For finally coming up with a real cure ND speady clear up rate.

Really reduced healing time so absolutely worth the money but it is pretty uncomfortable to use.

Seems like it worked well, prevented the cold sore from getting more inflamed/spreading/getting angrier.After one use, the sore practically scabbed over.I feel like maybe a scar has been left, whether this is the cold sore falling off too early or from this, unsure but I'd have a scare over a sore any day

I never normally write reviews but I bought this waiting for my next cold sore and when it eventually reared it's ugly head, I missed the tingle but used it while it was just a small blister. It's a bit hot but nothing you wouldn't be able to handle for 3 seconds, I done it twice and I can honestly say I felt like it slowed it down and sped up the healing. I use cold sore patches to prevent spreading and after 4 days I'm almost fully healed. Cannot quite believe it. These have haunted me for the past 15 years and it feels like I might finally have them under control and I've had some nasty looking ones. I wouldn't use it once the cold sore has gone too far to be fair, but I think the point is to use it at first instance. Really happy with this purchase and the fact it's a reusable device. Will be carrying this everywhere now.
