Praise the Mavala!
My baby is 17 months old, and this worked in just one day. She started sucking her thumb around 3 months old and never took a pacifier. Since then, she always sucked her thumb in the car seat and while sleeping. I honestly found it hard to look at, but I planned to address it closer to age two, when she might better understand. Recently, she started sucking much more aggressively. The skin on her thumb became raw, cracked, and scabbed over, and it clearly looked painful. It also wasn’t healing even after a long time. I knew she was still very young, but at that point I decided to try this product. I do want to mention that the taste is extremely bitter. The first time she put her thumb in her mouth, she immediately stuck her tongue out, smacked her lips, and clearly hated the taste. She kept making faces and licking her lips in confusion — but that bitterness is exactly what made this work. The result was a complete success. She stopped sucking her thumb after just one day. The first night, she tossed a little in her sleep but didn’t cry and slept through the night. I plan to continue applying it for another 1–2 weeks just to be safe. I’m incredibly grateful for this product — the bitterness may be unpleasant, but it is truly effective.

Worked on my 2 year old toddler
So i was reccomended this by my dentist and i didnt think this would work. My 2 and a half year old toddler sucks her thumb and i have tried many things to stop her. I was told that she needed to stop and it worked!! At first she was freakung out it tasted bad and drank water but eventually that same day she got the hang of it and by day 2 and 3 she was done with her thumb!!! I only reapplied once. Its been about 6 days and she doesn’t suck her thumb anymore!! My husband tried it out of curiosity and said it tasted super bitter that the flavor stayed in your mouth in once spot where you licked it lol.

I honestly can’t believe how well this worked!
My 4.5-year-old daughter has been sucking her fingers for years, especially when she was tired, watching TV, stressed, and while sleeping. We were constantly reminding her, “Fingers out of your mouth,” sometimes what felt like every few minutes. Nothing really worked. I actually bought Mavala Stop about 2–3 years ago and tried it back then, but it didn’t help at all. Recently, I found the bottle again and decided to give it another try. The difference this time has been incredible! As soon as she tasted the bitterness, she stopped putting her fingers in her mouth. We are now almost FOUR WEEKS in, and she does not suck her fingers at all during the day. Even at night, she has almost completely stopped. I think I’ve only noticed her briefly putting them in her mouth two or three times during this entire period. Her nails on those fingers are finally growing normally, and the irritated, bumpy skin she had from years of sucking is already healing and looking so much better. I’m honestly amazed. After years of constantly reminding her to take her fingers out of her mouth, I never expected something this simple to make such a dramatic difference. If you tried this when your child was younger and it didn’t work, it may be worth trying again when they’re a little older. That was definitely the case for us. I’m one very happy mom. I just wish I had tried it again sooner

More for thumb suckers
Even though this polish was effective for me and my grandfather, it did not work for my LO. She sucks her pointer finger and I think because her nail isn't touching her tongue, she couldn't taste the polish. I did have her lick her thumb to see if she could taste it and she didn't like the taste at all, but it still wasn't enough to make her stop I still think it's a great product. When I tried it on myself, I was utterly disgusted by the taste. It tastes as if you licked acetone. And the taste just lingers! It makes you really regret putting your finger in your mouth. Great for nail biters, but might not be enough for determined finger suckers

potent or not?
Does anybody ever read a 5-start review of a product that rates so highly? Yes, this product worked for me. And when I say me, I mean a 50 plus year-old who still bites finger nails. Over the years, my nail biting has gotten so bad that nails ripping into the flesh, dripping blood. And when I finally resolved myself, that I will always have to wear acrylics, I learned that my biting habit will eventually find a way to naw off the acrylics too. That's when decided for this: the most bitter substance known to humanity. This product delivered. After a week, I no longer want to put those fingers in my mouth. No surprize there, seeing that this is already a highly rated product. Why I'm writing this note anyways? Well, I did want to warn those sensitive souls out there. If you get your hands on a good batch, the bitterness is extreme. And yes, it goes on food even hours later. And yes, I can still detect it on my fingers, even 24 hours and a shower later. If your problem is not so serious, perhaps go for for something more herbal instead of this.

VOMIT INDUCING
Bought this to use on my thumb sucking son. He’s 23 months old and been sucking on his thumb since he could figure it out. I have no issues with thumb sucking however his teeth were showing signs that he needs to stop. I put it on around 1600 and he would make a disgusted face when he tried to suck his thumbs which was great, cause he would immediately stop and pull them out of his mouth. However, when it came time for bed time (1930) we did our usual read books before bed and he cuddles up next to me; well he also did his usual put his thumb in his mouth and he must’ve done it too long because he immediately projectile vomited all over the two of us; proceed to change him and give him a bath. I then lay him in bed and he yet again goes back to the thumb and as I’m not even a step out of his room and he is sitting up projectile vomiting again. So two baths in less than 10 minutes. I then made sure to use nail polish remover and scrub his thumbs intensely to remove this product so he can get some sleep. I made sure to suck his thumbs myself after cleaning them both to make sure the product was removed. Needless to say I feel like a horrible mom because while I’m trying to do what’s best for my child, the vomiting was not worth it. All this to say, the product works but I would make sure to either apply when you can observe your child entirely or wait until they’re slightly older to understand why you’re applying this product to their thumb/finger.

Great disgusting product !
Got this for my husbands chronic nail biting . He HATES IT (bc it’s so nasty when he tries to bite) lol which makes me LOVE IT. It’s DISGUSTING he says which prevents him from wanting to bite. Now, the only downside is this polish will get on your food if you cook with your hands nomatter if it’s been days since applied . You can literally taste it on whatever is touched so wear cooking gloves or something to protect your hands if you cook with this polish on. Other than that , this product has a 5 star from me. Oh and it is tiny , like a baby dolls nail polish but it’s enough to reapply several times and hopefully by the time you run out the biting urge has completely disappeared anyway.

Finally Broke a Lifelong Habit!
After years of trying to stop biting my nails, I finally decided to give Mavala Stop a try. Here’s my experience with the product after several weeks of use. What I Liked: It Really Works: The primary feature is the intensely bitter taste, and it delivers. The first time you unconsciously put your finger near your mouth, you'll know it. This immediate, unpleasant feedback is highly effective at building awareness and breaking the automatic habit . Easy to Apply: The application is just like a clear nail polish. It goes on smoothly and dries relatively quickly, forming a transparent coat on the nails . Long-Lasting Formula: A major advantage is that it survives hand washing. The taste deterrent remains active, so you don't have to reapply it multiple times a day. Most users find one application lasts about two days, making it convenient and cost-effective . For the Whole Family: This product is designed for anyone over the age of 3, making it a solution for both children and adults struggling with nail-biting or thumb-sucking . What to Consider: The "Smell" Factor: When first applied, it has a distinct chemical or "nail polish" smell. However, this odor does fade quickly after it dries on the nails . Texture Can Feel Sticky: Some users note that the polish can feel a bit sticky or tacky for a short while after application until it fully sets . Requires Consistency: Breaking a habit takes time. You need to be consistent with reapplication every 2-3 days for at least a couple of weeks to see lasting results . Final Verdict: Mavala Stop is a highly effective and practical product for tackling nail-biting. While the initial smell and slight stickiness are minor drawbacks, the powerful bitter taste and long-lasting formula make it a worthwhile investment. It successfully helped me become conscious of my habit and break the cycle. I would definitely recommend it to anyone looking for a solution.

Best beauty Decision ever!! 5* product which helped me regain confidence
Amazing product. Does what it says on the tin. I’ve bitten my nails for almost thirty years. I once stopped biting them for about six months but only because they were in artificial nails always. But there’s never been a time where I’ve had them exposed and not bitten. It’s been a real battle. My nails have therefore always looked bitten, unhealthy, malnourished and quite disgusting. I could only go on dates if I had fake nails. Playing pool, typing, holding a microphone or even gesturing became quite embarrassing with these nasty nails. I always felt embarrassed and disappointed in my self. I decided to try a bitter tasting polish as a fix. Best decision ever! This one tastes so Terrible and each coat lasts for days so you only have to reapply every 3-5 days depending on how often you wash. That means even though it’s a small bottle, it will last you months. I started using this on the 23rd of September 2018 and because of how bitter it tasted, the aversion started immediately. I stopped biting immediately but would initially still try to just have the fingers around my mouth but the taste is so nasty and long lasting that i actually became used to keeping my hands away from my mouth and even hated the idea of my hands going near my face. Do keep the bottle tightly sealed and clean as mine leaked and so it’s almost empty. However, even though I only used it for six weeks, I’ve now stopped biting my nails and instead obsess about having a healthy nail care regime which consists of pushing the cuticles back, painting them and applying nail hardener. My nails have grown leaps and bounds as you can see from the before and after photos (taken 6-7 weeks apart). I can now have a full manicure, paint them and flaunt my nails. They look amazing, I get complements from friends and family but they are quite weak due to extended Time spent biting for almost 30 years plus lots of gels, acrylic and stick on nails. So I am now rather focused on treating them and getting them strong and healthy. I can’t explain the joy, peace, confidence and freedom I feel from using this. It’s honestly changed my life. My family and friends are so proud of me. Thank God. Cheers to the manufacturers of this and the amazon seller. I’m so grateful: you changed my life.

Cumplió con su objetivo
Tengo un hijo de 15 meses que desde los 6 meses empezó a chuparse el dedo gordo a cada momento dle día y siempre para poder dormir, el odontopediatra nos dijo que tenía que eliminar esa maña ya que podría causarle problemas futuros a su paladar, nos recomendó usar este producto, supongo por la edad que ya tiene. Primero probamos pidiéndole no usar el dedo y en algunas ocasiones nos hacía caso pero rápidamente volvía a ponérselo, cuando lo enviábamos a la guardería le poníamos y sobretodo en las noches, siempre nuestra primer opción fue pedir que no lo hiciera, llevamos 4 días de usarlo en estos últimos dos días ya no ha hecho por meterse el dedo así que el producto fue un gran apoyo. Esperemos que siga así sino nos volveremos a apoyar en el producto, funciona de maravilla intenta chuparse el dedo e inmediatamente deja de hacerlo, intentó usar otros dedos entonces tuvimos que ponérselo en todos para que no buscara alternativas.

Does exactly what it says it would
Been a lifelong nail biter. I'm worst in the car where I do it absentmindedly. Was a bit sceptical about how good this stuff would be, or how long lasting it would last, but my fears turned out to be unfounded. It is awesome, tastes disgusting, and it very hard wearing. It's almost invisible unless you're really looking close, and the few times I've forgotten about it, and started to bite a nail, I'm given a very swift reminder not to do it again. The taste is bitter, and stays in the mouth long enough for you to not want to do it again. I sit here about two weeks into using it - nails are growing back nicely, no more sore fingers - nails are actually starting to catch on surfaces if I rub my fingertips over things. Amazing. I imagine I'll keep up the treatment for another couple of weeks, then stash the little bottle somewhere, and if I start to slip back into old habits, just do some shorter treatments as necessary, but I'm hoping this will help me break the association completely. If you want to stop - couldn't recommend this stuff highly enough.

She's now 4 and doesn't really suck her thumb anymore
Worked for my daughter. She had been sucking on her thumb since she was a baby. At around 3 and a half, I started using this. She's now 4 and doesn't really suck her thumb anymore. It's important to note that I never forced it on her. We had a discussion (not sure how much she understood) and she agreed to wear the liquid. One thing is for sure, the taste is horrible.

Meilleur que ses concurrents
Après avoir essayé plusieurs marques. C'est bien le seul qui ait un goût suffisamment puissant repoussant sans pour autant finir sur chaque chose que l'on touche. Attention cependant, il s'agit d'un vernis brillant et non invisible !
