Why Other Treatments Have Failed

If you've tried multiple antifungal products without success, the problem isn't your dedication—it's the treatment limitations.

  • Strongest Formula: Most OTC treatments contain only 1% active ingredients that can't penetrate thick, infected nails. OnyHeal delivers 25% Undecylenic Acid—maximum strength—to eliminate deep-seated infections.
  • Precision Application: Our precision pen targets exactly where needed without mess or cross-contamination.
  • Natural Components: OnyHeal combines maximum-strength Undecylenic Acid with therapeutic Tea Tree Oil, Oregano Oil, and Manuka Oil for comprehensive elimination.
  • Full Compliance: OnyHeal absorbs instantly with no rubbing required—easy to use consistently twice daily.

The difference is professional-strength treatment in a format designed for real results.

How Maximum Strength Formula Works

(NOMBRE) doctor-approved formula delivers professional-strength results through:

  • 25% Undecylenic Acid - Maximum legal concentration disrupts fungal cell membranes
  • Tea Tree Oil - Natural antimicrobial properties eliminate infection
  • Oregano Oil - Powerful antifungal action targets resistant fungus
  • Manuka Oil - Enhanced penetration and tissue healing
  • Clove Bud Oil - Additional antifungal support and protection
  • Vitamin E - Promotes healthy nail regeneration

Precision pen delivery ensures maximum-strength formula reaches infected areas directly.

Real Results in 4-5 Weeks

  • Week 1

    Yellowing begins to fade, nail texture starts improving

  • Week 2-3

    Significant color clearing, reduced thickness becomes noticeable

  • Week 4-5

    Dramatic transformation - clearer, healthier-looking nails

Frequently Asked Questions

How much product do I get in each pen?

One pen can be used to treat multiple affected areas of the skin & nails, including the skin around multiple toes or fingers, depending on usage frequency.

Can it prevent further fungal infections?

Yes, OnyHeal´s maximum-strength 25% Undecylenic Acid formula is specifically designed to both eliminate existing fungal infections AND prevent reinfection. The antimicrobial botanical blend (Tea Tree Oil, Oregano Oil, Manuka Oil) creates an inhospitable environment for fungal growth even after treatment is complete. Unlike basic antifungal creams that only treat active infections, (Nombre´s) professional-strength formula provides ongoing protection against the recurrence that causes so much anxiety for fungus survivors.

What’s the standard shipping time?

Orders usually ship within 2-3 Days, and delivery typically takes 7-8 business days (domestic).

What benefits can I expect?

  • Visible nail color improvement and reduced yellowing within 4-5 weeks of consistent use.
  • Elimination of thick, crusty nail texture as healthy nail growth replaces damaged areas.
  • Confidence to wear open-toe shoes, sandals, and go barefoot without embarrassment or shame.
  • Long-term protection against reinfection when used as directed for complete treatment cycles.






Is OnyHeal chemical-free?

Our product combines the maximum-strength active ingredient (25% Undecylenic Acid) with a natural botanical blend including Tea Tree Oil, Oregano Oil, Manuka Oil, Clove Bud Oil, and Vitamin E. While the active antifungal ingredient is a proven compound, our formula is free from harsh chemicals, parabens, artificial dyes, and synthetic fragrances that can irritate sensitive skin. This gives you professional-strength effectiveness with a gentler, more natural approach than traditional antifungal treatments.

    Patience...long term but highly affective

    I fractured my big toe 2 years ago and then got a fungal infection the toenail has fallen off and turned blue multiple times and is extremely painful sensitive Short of taking the anti fungal medications which is highly toxic to your liver and kidneys I decided not to go that route I've tried other topicals. Please be patient I have tried this for a month and oh my God half my toenail has completely healed and grown back I probably have another month of treatment 2-3 months to go but it is a game changer I'm applying a photograph and you can see where the toenail Polish is versus the new growth the ugly green fungal growth is at the tip and the new growth is at the base. I work medicine 100%safe

    Anti fungal pen

    As of now, I’ll give it 5 stars. Decent price, and get 3 pens. I didn’t know it came with a pack of files.
    I will update later. But I am going on to the end of week 2, do I see a difference? I do think so. After shower, and the nail is dry, I trim if needed, then file down the top of nail and apply. At night I’ll wash foot, dry and re apply before bed. I don’t know if it’s the filing or is the product actually working? I want to think it is. Again, I’ll update this after week 4.

    Finishing up week 3, new nail is showing with less yellowing at nail bed. Will update again at the end of week 4. So far, I’d say it’s worth it! But, you have to make sure you apply once in AM and once in PM. EVERYDAY!

    The second picture is week 4, slow progress, but new clean nail coming in at nail bed. This has been going on for YEARS. Will update as this continues. So far, I’m a believer. Stay tuned for more updates.
