Important! Please read!

John. Q. Public.October 7, 2025

Ok, so I have some info to share in hopes to help those who may have a similar issue; Toenail fungus! This product is a great place to start, but it is not a product intended to eradicate the foul fungus that has snuck into your life like a thief in the night! What this product does do however is VERY CRUCIAL to get rid of toenail fungus. Kerasal softens up the toenail, and essentially “opens up the nail” to allow you to get at the fungal spores. It also makes your nails look quite healthy, and you will see a noticeable difference within just a few days. The problem there is that people think they got rid of the fungus and stop treating it. That is a fail. It takes MONTHS to kill off toenail fungus. No one here wants to go to the doctor for this, and the OTC stuff you get can possibly help, but it’s unlikely. If your nails are very bad, it will take you about a year to finally get your toes back to normal. So, what to do? I have your solution! First off, get a small spray bottle. Like 8oz or so. Make a mixture of hydrogen peroxide, and Listerine. You will use this daily, once in the morning, and again at night. This mixture kills several types of fungus. It would also be useful to get a foot manicure kit. Use that to scoop out under your toenail, and around the edges. This will allow all of the products to get into, and under the infected toenails. You will use the Karasal as directed. I provide home healthcare, and a common issue with the elderly is toenail fungus. It can cause quite a problem over time; causing infections, inflammation, ingrown toenails (ouch!) and unsightly looking nails that are thick, yellow and embarrassing 🙈 Don’t worry, it will be ok in time. Another thing you can do is go outside on sunny days and let your feet bask in the sunshine ☀️. The U.V. Light also helps kill fungal infections. So, when purchasing this product, please understand that it does not kill fungus. It merely helps you to get your nails ready for he other products you will need to use. So, here’s a step by step guide to help you. 1) Get this Kerasal and use as directed. 2) Make a mixture of hydrogen peroxide and Listerine. Use this at least 2x daily. More often if possible. 3) Use a manicure tool to open up the edges of the fungal infested nails, and scoop out the white gunk that accumulates. 4) Get some 100% pure Tea Tree oil. After your first week of Kerasal, start applying the oil on the nails 2x daily. I apply the Kerasal, let it dry, then apply the oil. I use it at full strength, but if your skin cannot handle that potency, then dilute the Tea Tree oil with a carrier oil, like coconut oil, or olive oil, veg oil, etc. Tea Tree oil has natural fungal killing properties. I know it’s a lot. You’d think there would be easier ways, and if your issue is serious, please go to a doctor. You will spread the fungus to others through the shower, and even carpet, or laundry! Fungus is a sneaky beast! If you use all of the techniques I shared here, you will eradicate that gross fungus, and have nicer looking nails! Be patient, do it all routinely, and eventually you’ll be showing off your feet 🦶 lol. As for Kerasal, it’s definitely a 5 star product. If you don’t have toenail fungus, it makes your nails look fantastic! Great for keeping healthy nails! Good luck and I hope this helps you. Read more

Amazing. Works great. Even if your toenail is really bad.

Katie O'loughlinJune 23, 2022

I was amazed by how well this works. It’s pricey, but worth it. I was very ill for so long that i was unable to take care of my left big toe nail for over a year when i could see it needed care and it was getting worse. My nail ended up thick and yellow. This is really embarrassing. I am writing about this anyway to let people know who have a serious, untended, far down the road, problem with their toenails that this gel works really well and can actually clear it up. This might also be helpful for anyone taking care of someone, especially if it’s someone they love, that is very ill and has this problem. When i told my mom recently about this gel and how well it was working on my long term troubled toenail that had become quite bad off, she told me that the last few years before my dad passed away, when he was really ill, that his toenails had gotten really bad. Narly, thick and yellow. I wish my mom and I could go back, so that this gel could be used on his toenails so that, on top of being so ill, he wouldn’t have to feel the terrible embarrassment of having his toenails all damaged, hard and yellow from fungus, where people could see, and not even be able to take care of it. I don’t want this to happen to anyone else's loved one. I had no idea it could be cured so easily. I had heard, a lot, that serious fungal issues with your toenails could be really, really difficult to cure. I had heard of people losing their toenails. I thought i had left it so long that I might lose my toenail. I didn’t know what it might take to cure the fungal issue and have it gone. I thought I might need to take oral medication and put medication on the nail also and that maybe still nothing would be able to get to the underneath of the nail. I thought that a doctor might have to remove the nail. That seemed really painful. And I didn’t know if the toenail would grow back. It would be so embarrassing to lose my toenail and have to explain to people why. After all that time and worry I found out that all it takes is putting this gel on. For the first 2 or so days I put the gel on as often as was directed, but I’m still quite ill, so now it’s every other day to once every 3 days. And even with intermittent treatment with the gel, the part of the toenail that is growing out is totally clear and healthy. And the part of the toenail that was thick and yellow is now no longer yellow. It is cloudy white and on the side it’s going clear. This gel is amazing. I had a few other bits of trouble on other nails. Those are cleared up or clearing up quickly. My feet were having a bit of itchy trouble. Between toes seemed problematic (again embarrassing.) I got Lotrimin AF spray. I spray it all over my feet and in between my toes when I put the gel on my toenails. My feet are no longer itchy and my toenails are totally on the mend. I highly recommend Kerasal Fungal Nail Renewal. Read more

Instructions suck but product seems to be working. We will see.

CustomerAugust 21, 2025

My dr. recommended these to help clear up a toenail that had gone black. I went through about 10 packs of these and they weren't working. Then accidentally one morning, I wore them overnight in bed, the inside clear patch had slip off, I noticed that it had teeny tiny writing on it so I grabbed my magnifying glasses and read "REMOVE". Dozens and dozens of packs of these and nothing ever said to remove sticker 1, then sticker 2, and then sticker 3 (which can't be removed until sticker 1 is off. Read more

Visible results / good value for money

Marian FieraruJanuary 9, 2026

Been using it for just 1 week and I can safely say it brings results. My toe nails that were affected by fungus for so long start looking better and the nail color got a lot whiter. I’ll keep using it until it’s completely gone. Will definitely buy more for my parents too. Recommending this product to all of you reading this comment. 10/10 Read more

⭐⭐⭐⭐⭐ So Good I Ordered a Second Box!

MahmudDecember 6, 2025

I’m genuinely impressed with how quickly these Kerasal Nighttime Renewal Patches started improving the appearance of my nails. The overnight treatment makes it incredibly easy—just apply before bed and let it work while you sleep. After a few uses, I could already see a healthier, clearer look to my nails. I actually ordered a second one because that’s how good it is. Highly recommend for anyone looking for real results without hassle! Read more
