Why Most Treatments Fail
And why Arynez® is different.
Fungus Hides UNDER The Nail
Most creams sit on top of the nail surface. Only 0.1% actually penetrates through. The fungus underneath stays protected and keeps growing.
Precision Applicator Reaches The Source
Arynez's pen tip delivers 25% Undecylenic Acid directly under the nail, into the nail bed, and along the edges where fungus thrives.
Clinical-Strength Formula
25% Undecylenic Acid is the maximum strength available without prescription. It disrupts fungal cell walls and prevents regrowth.
3 Simple Steps
No mess. No guesswork. Takes 30 seconds.
Clean & Dry

Apply With Precision
Use the pen tip to apply directly under the nail, along edges, and across the nail bed. Get into every crevice.
Let It Absorb
Allow 5 minutes to fully absorb. Apply twice daily for best results. Most see improvement in 2-4 weeks.

Questions?
We've got answers.
How long until I see results?
Most users notice reduced itching and irritation within the first few days. Visible nail improvement typically occurs after 2-4 weeks of consistent use. Full nail restoration can take several months as healthy nail grows out—toenails grow slowly, but you'll see steady progress.
Why haven't other treatments worked for me?
Most topical treatments fail because they can't penetrate through the nail to reach the fungus hiding underneath. Creams sit on the surface while the infection thrives below. Arynez's precision applicator delivers treatment directly under the nail, into the nail bed, and along edges where fungus lives.
Can I use this on fingernails too?
Yes! Arynez is safe and effective for fungal infections on both toenails and fingernails, as well as surrounding skin affected by athlete's foot or ringworm.
How do I use the pen?
Clean and dry the affected area. Use the precision tip to apply directly to the infected nail, under the nail edge, and around the nail bed. Let it absorb for 5 minutes. Apply twice daily for best results. No wrapping or bandaging needed.
How long does one pen last?
Duration depends on the size of the treatment area and frequency of use. Most users find one pen lasts 2-4 weeks with twice-daily application.
What if it doesn't work for me?
We offer a 90-day money-back guarantee. If you're not satisfied with your results for any reason, contact us for a full refund. No questions asked.
