Maximum-strength topical therapy for nail fungus, formulated with 25% undecylenic acid — the highest OTC-strength antifungal active available.
What it does
Treats the fungal infection that causes nails to become:
- Thickened, yellow, or discolored
- Brittle or crumbly at the edges
- Lifted or separating from the nail bed
- Developing debris underneath
Also treats the surrounding skin so the infection doesn't seed back into the nail after it clears.
Active ingredients
- Undecylenic acid 25% — clinically-established OTC antifungal; disrupts the cell walls of the fungi responsible for nail infections
- Tea tree, oregano, manuka, and clove bud oils — natural antimicrobials for added support
- Propolis extract — supports skin healing
- Vitamin E (tocopheryl acetate) — nourishes the nail and surrounding tissue
How to use
- Clean and dry the affected nail and surrounding skin. Gently file down any thick areas.
- Click the pen until the brush tip is saturated (first use may need a few clicks to prime).
- Paint a thin layer over the entire nail, letting it flow under the front edge and onto the surrounding skin.
- Let it dry fully (1–2 minutes).
Apply twice daily — morning and night — for best results.
Expected timeline
Nail fungus is stubborn because the infection lives in the nail matrix, and nails grow slowly. Realistic expectations:
- Weeks 2–4: Active fungal growth slows; nail feels less brittle
- Months 2–3: Clearer new nail starts growing out from the base
- Months 6–9: Most users see full clear-nail replacement as the healthy new nail fully grows in
Consistency matters more than anything — skipping applications lets the fungus recover.
Important
- Diabetic? Talk to your healthcare provider before using any foot antifungal.
- Patch test first if you have sensitive skin or known sensitivities.
- Keep using it for 2–4 weeks after the nail looks clear to prevent reinfection.
