This product worked!!

Verified Customer

I've had a discolored toe nail for years, and been to two podiatrist who sent a piece of my nail for testing and it came back as a toe nail fungus (can't really remember the name) my options were an oral medication, removal, or laser (which is quite expensive) One of my veteran friends recommended that I try Treatonic, so I decided to give it a chance. I've been using this product consistently for a few weeks and already noticed a drastic difference. I know that it will take awhile for it to be completely healed, but I know for a fact that this works and I will continue to use until completely healed.

The Best so far

Seriously the best product out. I have started to get some toe fungus on one of by big toes after i had dropped something heavy on it and the nail was bruised. after the nail started to regrow is caused some fungus. This product has helped so much. i use it twice a day, file down the nail 3 times per week.. this is my second bottle. my first did everything it needed too, after the regrowth of the now non fungal nail, i have issues with ingrown nail on one side and it has what looks like a small area of fungi. this review is for my second bottle which i know will help correct this issue..

It works!

I had some pretty aggressive black-toenail on both my big toes. Really black. I read about the claims of this product and thought I'd give it a try (I'd tried all the athletes foot creams to no avail). I began using this maybe 14 months ago, twice a day and darn if both toenails didn't heal! Yes, it took nearly 6 months for one of my toenails to heal (it was very gnarly!), but now both my big toenails are clear as day! I use this product now after a workout as a preventative. Even works well between the toes to eliminate fungus from building there. I highly recommend this product!

It actually works

I've been treating a bad toe nail for YEARS. I've tried about every treatment out there. I stumbled upon this gem and ordered it. I started using it and noticed the strong smell of vinegar. I actually put in a request for a return (which was accepted) because I figured it to just be like every other thing I've tried. Then, I noticed my nail was starting to grow HEALTHY. I never returned it and kept using it, everyday. I've been using it since March and my bad nail is almost completely grown out healthy. This stuff actually works. I use it twice a day and that had been working for my stubborn nail.

Be patient

You need to give this product time to do its work. I applied the product twice a day for 45 days (finished the bottle) before I saw significant results. There is some improvement initially but the full effect doesn't come until later. To be clear - this product is not a cure. It doesn't claim to be. Pureskin Nail Renewal keeps the spread of the toe fungus in check (biggest benefit) and softens the nail and provides an overall improvement in appearance. The only negative is that the brush applicator frequently detaches from the cap and you have to go fish out the brush and brush shaft from the bottle with tweezers and reconnect it to the cap (pressure fit).

WORKS!!

I had minor toenail issues with both big toes, nothing major, but I tried several treatments and none of them worked as well, nor as quickly as this one. I've been using this Pureskin Fungal ointment for 4 weeks, twice a day, and the affected nails are almost 100% clear! I've gradually been trimming off the dead areas on both toes, now it's just a matter of allowing them to grow out. This is by far the best treatment I've used, and I saw results in just a few days. I will continue to use a while longer to prevent any recurrence. Highly recommend!

Best product for nail repair

It is advisable to be patient with this process. Given time it will improve nails greatly. I used a fine nail file every night before application to toenails. Using the nail file removes dead growth etc. My toenail started out as damaged as the picture in the packaging. It took a few months of use along with the fine nail file before application to see marked improvement.
I tried Vicks, and many other things that did not work as well as this!
Thank you for making such a great product.

BUY IT!

I’ve been using this since I got it on December 30th of 2022. I apply it about 2-3 times on my nails that have been infected daily. And omg, It’s only January 16th, and the fungal infection on my thumb and index finger is almost completely gone. My doctor had recommended a topical ointment to me previously called Mupirocin, and even with using the product as prescribed (she told me to also put a bandaid over it with the cream which was so annoying and messy) my fungus still persisted and actually got worse! This product does exactly what it’s supposed to, and I highly recommend it. Beware, it has a very strong smell, but it does dry very quickly on the nails. I honestly believe the scent is a indication that it’s some good stuff lol

Amazing and works like magic! So so happy!

I was absolutely surprised with this product!
I cried when I saw results! I was so scared to try it but wow at the results. I use to have these intense white spots (I love kickboxing and floor work and I tend to really wear my feet out) I promise you!!!…within a day I saw results!!
I really wish I had before pictures but I didn’t think about it because this product fell onto my lap. I’m grateful and so happy. Please please give this a try!
As silly as this may sound; I can’t wait to run out; so I can purchase again!
🙏🏼

Works with Time

This works very well as long as you are willing to be persistent. You have to make sure you follow the instructions how to apply the antifungal treatment. Clean your toes , apply as directed , use the filer to file down the old application.. You have to be patient. It took a month before I noticed a difference and 3 months before the fungus was completely gone and my new nail was growing out. Maybe it took so long because it was my big toe, not sure. It's been 4 months now and my top half of my nail is new but still soft and the bottom half is the old nail and no fungus.

Best alternative to a Doctor visit.

I have had some degree of toenail damage most of my adult life, and have kept it under control. Now I have a bigger problem with mis-shaped big toe nails, and other nails showing damage. Rather than going right to the doctor, I decided to try this product. I have to say, it is doing the trick. It’s been about 10 days and I see a marked improvement, and believe the problem will be gone in a another week or so, and with new nail growth.

It works!!!

I wanted something to fix the fungus that I got from leaving gel nail polish on to long and going Into a public pool which caused the fungus to get underneath the lifted portions of my nail. This product works ans is continuing to work. I use it as directed and have seen a difference in just a week! You will not be disappointed with this purchase. Plus it is a small family owned company instead of something mass produced from god knows where. Thank you so much for a great product!

It works.

I wish I had taken a before and after photo but I never thought it would work actually as my toe was bad (really bad). But lo and behold! It works. Been using it for over a week now and the natural color of my nail is starting to return. I didn't bother to soak my foot or use the nail file, so I am sure if you did it might work sooner, but I am super pleased. I suspect in another few days I won't be needing it anymore, but trust me, it works, and it works fast.

It works..if you follow the directions.

I purchased this brand about 6 months ago. I used it for a month or two and found that it didn't look like it was working. I then took the time to read the directions..I filed the surface of the damaged toenail in order for product to get to the fungus...having done this, I found that my toenail is now clearing up. The only problem I had was the brush sometimes will come off, and fall inside the bottle, so you have to get tweezers to get it out, and put it back in the hole...small issues for me..as long as the product does what it says.

Works with patience

This works very well as long as you are willing to be persistent. You have to make sure you wash your feet and toe nails daily and then apply antifungal and make sure you use it generously with paper towels under your feet in case it drips. It does take a few weeks. So be patient. I’m sure it’s because as your nail grows out, you have to keep applying so the old nail doesn’t infect the new nail coming in.

I was offered a bonus for writing a review, but I wouldn’t lie if it didn’t work. I depend on honest reviews myself and hate fake ones.

Ready for sandal weather!

I have struggled with a fungal toe nail for years, trying many topical remedies, and have resigned myself to just trying to keep it from getting worse. I have been using this product for 3 weeks and can already see improvement in the nail. It looks healthier, and the surface seems smoother to have some fun with color polish. The brush applicator is easy to use, just swipe it morning and night, and it doesn't seem to dry out the skin around the nail as badly as others I've tried. I also love the little nail file that comes with it. That's so handy for trimming and smoothing the nail.

This works!

My dad has suffered from nail fungal for year's. He was embarrassed to wear flip-flops in public because of it so I was on a mission to find something that he could conveniently use. I came across this and read all the most recent reviews and decided to give this a shot. He said the first few days his toes ached but it subsided on day 3he has applied it twice a day and every third day files and trims the toe nail. Wow in just two weeks his nail bed has improved tremendously and the fungal is steadily dying. I highly recommend this product 💯

GREAT PRODUCT! VERY EFFECTIVE

Got this product for my mom for her large toe infected with fungus. Amazingly, it’s worked sooo well. The discoloration under the toe is all cleared and the new nail is regrowing. I’m so excited. Will definitely buy more cos it’s an ongoing treatment and I definitely recommend this product. The packaging is very secured and tamper proof. It has a brush on applicator that makes it very easy to put on affected area. It’s liquid and with the brush too it’s really convenient to apply to affected area. This makes it possible to not have a messy situation. Will definitely buy more to complete treatment.

Frequently asked

How long does it take to see results?
It depends on your nail and the severity of the infection. A toenail grows out fully over 6–12 months, so visible change is gradual as healthy nail replaces damaged nail. Consistency matters far more than speed — which is exactly why we offer 100 days to try it.
How many nails does one kit cover?
Each kit contains 3 Day Pens + 32 Overnight Patches. Typical use is a daily pen application plus nightly patch across 3–5 affected nails. For a full multi-month protocol, most customers choose the 2-Kit or Full Protocol option.
Will the overnight patch stay on while I sleep?
Yes. The patch is designed with a skin-friendly adhesive that wraps and seals around the nail. Press the edges firmly when applying for the most secure fit through the night.
Can I use Treatonic if I have diabetes or other conditions?
If you have diabetes, peripheral vascular disease, or any underlying condition, please consult your healthcare professional before starting any new nail treatment protocol.
Why 25% Undecylenic Acid? Why not a lower concentration?
25% is the maximum concentration permitted for Undecylenic Acid under the FDA OTC monograph. It's topical only, so there's no systemic absorption and no liver-function monitoring as with oral antifungals.
Do I need to throw out my shoes?
No. The overnight patch is designed to physically contain shedding so there's less material reaching your shared surfaces. Routine hygiene — clean, dry socks and letting shoes air out — is good practice alongside the protocol.
What if I don't see results within 100 days?
Contact us for a full refund — no return shipping required. We built the 100-Day guarantee specifically because nail care takes time and we want you to be able to give it a fair trial risk-free.
Is this a subscription? Will I be re-billed?
No. Every option here is a one-time purchase. You will not be enrolled in any subscription or re-billed automatically.
