Scroll through the day
Fungus doesn't sleep. Your treatment shouldn't either.
The kit · at a glance
Meet the day-and-night system.
One simple two-step routine: a pen for the daylight hours, a patch for the night. The rest of this page walks you through a single day with it.
Day
The pen
25% undecylenic acid, brushed on every morning — dries clear in seconds.
+
Night
The patch
A hydrogel patch keeps working for 8 hours while you sleep.
Together they cover the full 24 hours — closing the gap where fungus comes back.
Morning · the day shift
The pen does the daylight hours.
A clear twist-pen delivers 25% undecylenic acid straight to the nail every morning — fast-drying and invisible, so it's on with your day in seconds.
- Maximum-strength antifungal
- Dries clear — no mess, no waiting
- Targets the nail and the skin around it
Noon · the science
Why half a treatment keeps failing.
The reason fungus comes back is medical, not personal. Most antifungals stay active for about 8 hours, then quit — leaving a daily window for it to recover. Treatonic closes the window.
Day pen · active antifungal
Night patch · overnight repair
25% Undecylenic acid
Maximum over-the-counter antifungal strength, delivered by the precision day pen.
24-hour coverage
Pen by day, patch by night — no 8-hour gap for the fungus to bounce back.
Overnight occlusion
The hydrogel patch seals in moisture for 8 hours, keeping the active working while you sleep.
Podiatrist-reviewed
The protocol is clinically reviewed by a podiatrist — built around how relapse actually happens.
Golden hour · the payoff
Real people, real regrowth.
Three full stories — with photos — from customers who got their feet back.
Verified★★★★★
"15 years of work boots. 15 years of thick yellow nails. I'm 8 months in. The big toe is fully restored. My grandson asked me to teach him to swim."
Verified★★★★★
"Caught it at the gym shower. Started Treatonic immediately. Day pen + night patch fits my training schedule. Caught it early, fixed it fast."
The payoff · in photos
And here's the difference.
Real customer photos, used with permission. We don't promise a fixed timeline — a full toenail naturally grows out over 6–12 months. This is what the protocol has done for people who stuck with it.
All before & after photos are from real, verified customers and used with their permission. We make no claim of a specific timeline or guaranteed outcome — individual results vary with infection severity, consistency of use, and natural nail growth rate.
Tried Everything Else?
If creams, lacquers, pills or laser never lasted — here's why this is different
Most products in this category only address one variable. Treatonic was engineered to cover the structural reasons fungus comes back.

It addresses all 3 recurrence drivers
Most products close one gap — Treatonic closes the nightly window, the protective shield, and the contamination cycle in one system.
OTC max strength — no Rx, no liver risk
25% Undecylenic Acid is the maximum FDA OTC concentration. Topical only — no systemic absorption, no lab monitoring.
Built for the long protocol
Toenails take 6–12 months to fully grow out. Treatonic is engineered for sustained daily use — with a 100-Day guarantee that gives the system time to work.
Night · the night shift
The patch takes the hours others miss.
A hydrogel patch works for a full 8 hours while you sleep — sealing in moisture and keeping the antifungal action going through the night, closing the gap that causes relapse.
- 8-hour overnight repair & renewal
- Hydrogel seals in moisture
- 32 patches — a full month of nights
Lights out · the kit
One kit. The whole 24 hours.
Day pen and night patch in a single box — everything you need to run the full protocol, sunrise to lights-out.
