Antifungal Pen Cures Most Athletes Foot Jock Itch and Ringworm - 25 Undecylenic Acid with added Tea Tree

This pen has cleared up my toenail fungus very fast. I am still applying it to keep the process going. Great product and easy to use. Read more

These are working! On my second tube now, after about 3 months of daily application. It is working, and the nails are growing out and sticking to the nail bed now as they grow out, fungus free. This is a s-l-o-w process though, so you have to give it time to work. I saw improvement in the first few weeks though. Be patient, and consistently apply every day, after shower in the morning. I like that the applicator has a small brush, which you can get in UNDER the nail. I think this is one reason it works so well. Expect it to take 6 months or so for that nail to grow out. All the treatment methods for nail fungus take this long-this is just an inexpensive option that you don’t have to see a doctor for a prescription type treatment. It’s working for me. Read more

I just got my pens 5 days ago and the first one is half gone BUT!!!!! I can already see a difference. The little files work very well and I sand them daily between applications. I did follow directions precisely and apply twice a day. First product I’ve tried over 5 years that actually seems to work. I think I will get about 10 days per pen vs a month but still worth the money. I can’t wait to see how much better they look by summer. Wish I had started at the end of last summer. Read more

Work good but it either one tube doesn’t work! My fungus is better but it has taken three orders and one tube in last order didn’t work! Read more

I’ve tried a few antifungal treatments before, but this pen-style applicator really stands out. The twist pen makes application super clean and precise—no messy creams, no touching irritated skin, just twist and apply exactly where you need it. That alone already makes it more convenient than most options out there. What really impressed me is how effective it is. After a few days of consistent use, the itching and redness noticeably calmed down, and the skin started looking much clearer. The formula feels strong but not harsh, and I appreciate that it includes tea tree, jojoba, clove bud oil, and aloe, so it soothes instead of drying everything out. The 3-pack is also a big plus. I keep one at home, one in my gym bag, and one for travel. Compact, no strong smell, and easy to carry around. Overall, this feels like a smart, hygienic, and effective solution for fungal skin issues. I’d definitely buy it again. Read more

At least 5 years ago now, seemingly overnight, my toenails became very thick, rigid, dry, and generally unsightly with all kinds of dents and cracking. Amongst other things that change for us as one gets older, this problem was making me self conscious, avoiding beach and lake trips with friends because I didn't feel comfortable wearing flip-flops anymore. I'd tried all sorts of things - topical fungus treatments via pen applicators (just like this one), foot soaks, biotin supplements, a variety of oils...nothing has helped. The worst part of this process as I'm sure anyone dealing with this issue knows, is the amount of time it takes to verify if one treatment or another is working. Toenails don't grow that quickly, so at minimum, you must commit around 2-3 months to a consistent treatment routine before you see any results. Even after that time, you may think things are looking better but are ultimately not really sure, so you continue for another few months before finally giving up, researching another solution and trying that...rinse, repeat. Suddenly 5 years have gone by and you've probably accepted the issue will never be solved but...then, hopefully, you come across Lunavia! I've been using it for about 6 weeks now. I just started my third pen, not sure if that means I'm using too much or too little. I do one full twist of the pen per foot, which pushes out a single visible drop of fluid to the edge of the pen brush. Instructions say to apply twice a day, after a shower (or something to soften the nail), so I shower in the morning, apply it, let it dry as I continue the morning routine before work, then when I get home, I do a tea tree oil epsom salt foot soak for 15 minutes, then apply again (trimming/filing nails about once a week or so). I've been pretty disciplined about this, though I've missed some days here and there due to various trips I've taken where it wasn't convenient or possible to do. After 6 weeks, this is the first treatment I've tried where I don't feel unsure about whether it's working or not, I can confidently recognize progress for the first time! Nail color is changing back to the way it should be, they are thinning out as they should, they're looking smoother, straighter... Everything I've disliked about my toenails the last 5+ years seems to be reverting back to looking healthy the way they used to, and I couldn't be happier about this. Next summer, I will be able to wear flip flops without feeling self conscious! I will say, these pens are pricier than others that also contain the 25% undecylenic acid. It's possible the cheaper options may work just as well, but I've already spent 5+ years trying all sorts of things at varying price points, so I opted not to go for the cheaper option this time. Give it a try! Read more

I used this product...3 tubes. My nails look better, but not healed from the fungus. I was going to get another 3 tubes, but the price has doubled on Amazon. I have found it elsewhere for much less. I am a good customer with Amazon, but this product is way over priced. However I plan on keeping up the treatment... Read more

I had 1 toe nail to use this on. I've been using it as the instructions say and have yet to see any change. The 3 pens did last a while though, I'm now almost out. I'm going to reach out to the seller. I'm willing to give it another shot but I think this is just snake oil. We'll see I guess. I will update if seller responds. ***UPDATE*** 11/24/25 After my review posted the company reached out to me and offered a full refund. The honor their the warranty and stand behind their product. While the product didn't work for me, I wouldn't hesitate to try it as the company stands by their warranty. I changed my review from 1 star to 4 star due to this. Read more
