## Description

Product description How to use HERPOthermHERPOtherm is very simple to use. First place the device onto the affected area and gently press it on to the skin. After pressing the button, the ceramic contact surface heats up to approx. 51°C for three seconds, when HERPOtherm then switches off automatically. Leave a treatment interval of at least 2 minutes between each application. Do not exceed a maximum number of 5 applications per hour on the same skin area. Clinical StudyHERPOtherm has been tested under using a cohort of 103 patients against topical acyclovir, the ingredient commonly used in cold sore treatment creams. The results showed that localised heat transfer from HERPOtherm was more effective in reducing the symptoms of cold sores than acyclovir cream and accelerated the healing time of symptoms by 50%. Study: Wohlrab J, et al., Clinical, Cosmetic and Investigational Dermatology 2013, 6:263-271).How does HERPOtherm work?The herpes simplex virus type 1 survives dormant in the nerve cells. If the skin or immune system is put under stress, the virus can reactivate and cold sores can develop. Topical antiviral medication can normally only shorten an outbreak by just half a day (Spruance et al., Antimicrob Agents Chemother. 2002). Creams containing acyclovir also contain other chemical substances, such as preservatives and emulsifiers, in addition to the active substance acyclovir. They are also not very discreet when applied to the lip.HERPOtherm works on the principle of local hyperthermia (concentrated heat therapy) and is therefore completely free from chemicals. A temperature of approximately 51°C is applied to a small, limited area of skin for 3 seconds. Proteins required for the herpes simplex virus type 1 to multiply are broken down by the heat. Experimental studies suggest that the body's own enzymes required for wound healing are activated by the application of heat. Ingredients Suitable for allergy sufferers Directions The application of Herpotherm Neo is very easy Safety Warning For children under 12 years of age only under adult supervision

Review: I was skeptical but ...not a SINGLE sore in 5 months! (+comments about some reviews) - 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.
Review: Effective at reducing symptoms and speeding recovery - I'm so glad I found this. I've had it for nearly a year now and it's been so worth it. I use frequently when I can tell there's a cold sore coming, and this product means it doesn't get full blown and it goes away faster. It's hot enough to make you wince, but it's preferable to the pain I used to get. Not a cure, doesn't stop it completely, but a big improvement.

### ⭐⭐⭐⭐⭐ Very impressed.
*by G***Y on 19 January 2026*

My go to cream had expired so I googled best cold sore remedy & found this. My cold sore had already got to the scab stage by the time I received the item. Concerned that other reviews had said it was very hot. I decided to try it on the back of my hand. There was heat but I would struggle to say it was hot. Hold it on your cold sore, press the button, it beeps and a green light shows, after a few seconds it beeps and that is the end of the treatment. I used mine a couple of times a day. The scab dried up much quicker than with any cream I’ve tried and was actually gone in under 10 days. I highly recommend this product.
