Editor Review

NailRENEW has been a leading product in nail fungus eradication since 2013 when it entered the market. This proprietary mixture of proven ingredients including mild surfactants and compounds result in a unique delivery system, the product of five years of research and development. NailRENEW is designed to kill fungal agents by penetrating underneath the nail bed where fungus develops and then spreads while also targeting surface fungus on top of the nail plate.

Quote from website: “NailRENEW™ is a pearlescent liquid with a low viscosity, it is designed specifically to penetrate the nail plate…. The active ingredient, Tolnaftate, is delivered throughout the nail using the mild solvent PEG-8 and a proprietary mixture of mild surfactants and compounds – the result is a delivery system that helps penetrate deep into the nail to fight off fungal infections.”.

After evaluating the product literature and label, we can confirm that Tolnaftate is the active ingredient in this formula the maximum amount permittedlink 1 (Federal Drug Administration) according to their monograph. NailRENEW works hard to target fungal agents by penetrating underneath the nail bed where fungus develops and spreads.

NailRENEW is a pearlescent liquid and is administered through a dropper bottle style tip that is measured for easier application. In the below product description, you can view images of the applicator tip and bottle top. The liquid has a low viscosity that was initially concerning but actually by design.

In rare cases, if you experience mild symptoms or discoloration as a result of acrylic nails, you may experience improvement in as little as 1-2 weeks as well as healthy regrowth within a little over a month. Immediate results included reduced redness, swelling, and reduced pain underneath the bed of the nail and the surrounding skin (if infected). NailRENEW promises a full 60 Day promise on all purchases or your money back, no questions.

After contacting NailRENEW customer support via email, they replied in 5 hours, and were able to confirm that the viscosity is normal and by design in order to help permeate the nail.

I’m unaware of any method to determine whether or not this product is penetrating the nail which is one of the more attractive features of the product. However, this products low viscosity does set it apart from the rest of the products which are more of the oil or paste variety in texture.

From the Website: NailRENEW is produced using active clinically proven ingredient for its antifungal properties. According to their website, NailRENEW is manufactured in an FDA-registered facility in accordance with GMP according to their website link 36.

NailRENEW’s formula includes a blend of mild surfactants and compounds as a delivery system.

NailRENEW holds the top rankings in our reviews from 2016-19 based on user feedback, value, and our own evaluation. For this reason, it is our recommended treatment for toenail and fingernail fungus. NailRENEW can be used to against all strands of nail fungus including white superficial onychomycosis, distal candidas albicans, and proximal subungal onychomycosis. NailRENEW ships the United States/Canada but is not available internationally at the time of this review.

Toe nails fungus

I got this from my mom. Use epsom salt in some warm water and soak your feet for 20 minutes. dry and repeat every day for a week It should go away in a week or so

Keep using it

I saw some improvement after the first month but I wasn't truly satisfied until the nail finally regrew. I have successfully clipped away and filed all the fungus off the toenail and it's a nice new nail. I'm going to keep using this product as a precaution so I don't get it again. This is great though and I'm really happy that it delivered as promised

by Belinda on Blank Business Name

I had some fungus under my toenails or whatever and it was starting to make me really concnered that it wouldn't go away on its own. This made a difference right away when I started using it (give it a month) and I'm still using it to make sure it doesn't come back. I think it's priced kind of high though but they all seem to be for some reason. I would recommend giving this a shot for anyone else who has the misfortune of dealing with this mess.. the worse part is I'm still not sure where it came from in the first place. Good luck.

by Anonymous on Blank Business Name

Give it 2 months minimum - it gets to the source of the fungus around and underneath instead of just the surface. Then you just clip away the bad parts.. its time consuming but its the only way I've found.

I'm so happy with this! Thanks!

4 months

I started using it about 5 months ago on two toenails while taking a multivitamin and have almost finished cutting away at the final bit of the last nail. It does work very slowly as others pointed out.. basically as fast as your nails grow if it's doing its job. It's also pricey, the last time I ordered it the price rose. Another thing is they say each bottle is suppose to last a month but for how many nails? I used 3 bottles on two and didn't need to order more until today.

Not bad

This product is not bad. The first few weeks I didn't notice much difference if anything at all. I contacted customer service who gave me some advice on how to use it and instructed me that I would see slow improvement overtime from the base of the nail as I clip away at it. I'm sticking with it but this is an ongoing thing. I'm seeing improvement but it's very slow going and I think my nails might grow slower then when I was younger. I file my nails usually before applying a drop to each which seems to help.


I'm very happy so far after using it for 2 months. Keep using it and you'll see.

Expedited shipping

I paid for expedited shipping but my package showed up 6 days later. I was refunded the cost of shippinghandling after calling in but I still don't have a good reason why. The product is good so far and I'm on the end of my 2nd bottle. I can see the new nail coming in. I wouldn't bother paying for priority shipping but if you don't get it in time call for a shipping refund, it was $12.

Since January

I've been using this since end of December/early January... definitely works!
