kure™ Antifungal Pen
"I'd hidden my feet in closed shoes for years and tried every cream out there. This actually reached under the nail edge and the new growth finally started coming in clear."
How It Works
Your 10-second twice-daily ritual for clearer nails
Prep
Clean and dry the nail. Trim and lightly file the surface so the formula reaches the nail edge instead of sitting on top.
Apply
Twist the pen and touch the tip to the nail, the free edge, and the skin folds around it the spots a cream skips over. A thin layer is all it takes.
Let it dry
Give it a minute to absorb before socks or shoes. No rinsing, no mess, no greasy residue.

Your Path to Clear
What to actually expect week by week, no fairy tales.
Days 1–14: Skin Relief First
The itch, burning, and irritation in the skin around the nail are usually first to ease. The 25% active goes to work on surface fungus where it can act fastest.
Weeks 2–6: The Surface Settles
Crumbling slows. The skin around the nail looks calmer and less inflamed. The nail itself hasn't changed yet and that's normal. Here's why
Months 1–3: Clear Nail Begins to Grow In
A nail can't repair in place it has to grow out. Healthy, clear nail advances from the base while the damaged part moves toward the tip. This is where most people quit too early. Don't.
Month 3+: The Damaged Part Grows Off
The infected portion reaches the end and gets trimmed away. What's left is the clear nail that's been growing the whole time. This is the moment people put sandals back on.
What's Inside (and what's not)
Undecylenic Acid 25%
the one doing the work This is the active ingredient the part that actually fights the fungus. It's recognized by the FDA as an antifungal for skin, and it's here at 25%. That number matters: most "maximum strength" products at the drugstore use only 1–2%, which is part of why they so often don't deliver. More active, applied right where the problem is.
Tea Tree Oil
the soother A plant oil that's been used for generations to clean and calm irritated skin. Around an infected nail, the surrounding skin gets red, itchy, and angry tea tree helps settle it down so the area feels better while the active does its job.
Vitamin E
the protector You're applying this twice a day, every day, for weeks. That much use can dry out and crack the skin if there's nothing to protect it. Vitamin E keeps the skin around your nail conditioned and comfortable, so sticking to the routine never feels harsh.

I had one nail that looked really bad and I almost gave up fixing it. After using this pen regularly I can finally see healthy growth coming in. It takes patience but it works and thats what matters.

Good solution for nail problems. It feels like it goes deeper than surface treatments.

I’ve been dealing with one really bad nail for months and nothing I tried seemed to make a difference. After using this pen consistently, I finally started to see clearer growth coming in from the base. It’s not instant, but it actually works over time which is what I needed. I also like how easy it is to apply without making a mess.

Honestly this is the easiest nail treatment I have used. No extra tools, no confusion, just apply and wait. My nails are improving little by little and I feel much more confident now.
Ive tried creams before but they didnt do much. This one feels different because it actually absorbs into the nail. Takes 3 months tho
i like it. no complicated steps just apply and thats it.
After using it for some time my nail became less thick and more normal looking. Im happy with the progress so far.
At first I didnt expect much because I tried other products before, but this one feels different. The formula absorbs into the nail instead of just sitting on top. After about two weeks I noticed the thickness reduced and the color slowly improving. It gives me confidence that I’m finally treating the problem properly.
I noticed my nail getting smoother and less brittle after about a week. It gives me confidence to keep using it.
good product. nails look healthier now.
Worth it.
