Most topical treatments fail to reach the actual infection. They sit entirely on the surface of the nail. Here is exactly why our formula produces real results.
We do not just put a tiny drop of active ingredients into our formula to make it look good on the label. We use exactly 25% Undecylenic Acid. This is the absolute maximum strength antifungal compound you can buy without a doctor's prescription. It floods the infected area to wipe the parasite out at its source.
Nail fungus survives by building a tough physical shield called a biofilm that blocks standard creams from reaching the infection. Our specific blend of natural oils breaks through that exact cuticle barrier. They soften the surrounding skin and dissolve the biofilm so the active acid can easily get underneath and destroy the parasite.
You do not have to struggle with messy creams or useless foot soaks that spill everywhere. Our applicator is built exactly like a cosmetic pen with a fine brush tip. You twist the base to release the exact amount of liquid you need, allowing you to paint the formula directly onto the damaged nail.
We know you have likely wasted a ton of money on fake remedies that do absolutely nothing for your feet. We give you a full 90 days to use these pens and see the clear nail growth yourself. If the treatment fails to work for you, you get every single penny back.
My big toe was cracking and peeling for months. I tried soaking it in vinegar but nothing changed. I started using this pen twice a day. Within four weeks, the damaged part grew out and my nail looks completely normal and pink again. I am so relieved.
I had thick yellow fungus on my big toe for two years. I wasted money on drugstore creams that just sat on the surface. This pen actually worked. The thick yellow crust dissolved and a healthy nail pushed through. I can finally wear sandals without feeling self-conscious.
The fungus spread to three of my toes and the nails became thick and ugly. My salon told me they could not give me a pedicure. I bought the three-pack and applied the liquid every morning and night. The yellow thickness is completely gone and my nails are clear again. I highly recommend this treatment.

It uses natural oils to dissolve the physical barrier the fungus builds. This allows the maximum strength acid to reach and kill the source of the infection.
Most customers see visible improvement in 2 to 6 weeks. Full healthy nail regrowth can take longer depending on the severity of the infection.
Apply the liquid directly to the affected nail and surrounding skin twice a day, morning and night.
Do not use on children under 2 years of age unless directed by a doctor.
No. Polish traps moisture and prevents oxygen from reaching the nail bed. This feeds the fungus.
90 Day Money Back Guarantee. Don't see improvement within 90 days? We will refund you. No questions asked.
