Stop Deterrent Nail Polish Treatment | Nail Care to Help Stop Putting Fingers In Your Mouth | Bitter Taste| Easy Application | For Ages 3+ | 0.17 oz

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.

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.

Bought this as it was recommend by my child’s pediatrician to help stop biting his nails/putting his fingers in his mouth and it worked! The very first day he kept putting his fingers in his mouth and got grossed out by the sour taste but was still curious about it…. After school on our way home he had a huge projectile vomit in the car 😭. Due to him sticking his fingers in his mouth and by day 3 he was hardly putting them in his mouth… I haven’t had to use it other than 3 times. And the third time was a just in case application.. the 2nd time was on day 2 because it wore of from too much washing his hands (outdoor play, school, before meals ect..)

I purchased for my child (age 3) had a persistent nail-biting habit. After trying reminders and other methods with little success, this product made an immediate difference. The polish goes on easily and looks clear and natural, so it doesn’t draw attention or feel like a “treatment.” The bitter taste is extremely effective—after just one or two attempts, my child stopped putting fingers in their mouth. It also helped discourage thumb sucking, which was an added benefit. I appreciate that it’s safe for children ages 3+ and doesn’t contain harsh ingredients. Very effective bitter taste,Easy to apply, clear and discreet,Safe for ages 3+,Helps with both nail biting and thumb sucking. But Needs frequent reapplication after hand washing,, Bitter taste may bother very sensitive children,,Slightly pricey for the size. this is a well-made, effective product that does exactly what it claims. It worked far better than I expected and helped break a long-standing habit.

Miracle product. Truthfully, I was really hesitant to used this item to stop my 2 year old’s thumb sucking habit (started around 4 months old). The dentist recommended trying to break the habit before my son turned 3. As he approached 2.5, I noticed he was sucking his thumb a lot more so I decided it was time to at least try to stop. I applied the polish to both thumbs before daycare drop off one morning (he only sucked one, but applied it to both just in case). Figured I would try it on a day where he had many distractions. He let me apply it with no issue. After it dried and like clock work, he put his thumb in his mouth. He instantly took it out and said “yucky”. After a few more attempted, he eventually started to stop himself before the thumb went into his mouth. It did take a bit longer for him to fall asleep at nap and bedtime that day, but it was to be expected since he had to find another to soothe himself to sleep. After the first day, I never saw him suck his thumb again. I continued to apply the polish for two weeks, but it wasn’t necessary.

Be prepared when trying this with a 1 year old. This product works, but caused my 1 year old to throw up, even after it was removed. The dentist recommended it, but the results were not the best. My child wouldn't go to sleep because he was traumatized from what happened and wouldn'tsuck his fingers. We got no sleep that night. He stopped sucking his fingers, but we had to stop using this completely due to the horrible results.

My daughter has always been a nail biter. I got this for her, within a month she no longer bites her nails. The horrible taste discourages her from biting… i went 2 months without putting it on her nails and she has not put her fingers in her mouth since.

I’m very impressed with this product! My son is 5 years old, and still sucks his finger when he zones out. We have tried EVERYTHING, including other similar products, and this is the only one that has worked!! It’s so nice that it lasts for multiple days! The other products used had to be reapplied constantly, so this has been great. I would definitely recommend!
