Step-by-step with tips
From hiding your feet to barefoot confidence

The hidden struggle
You know the feeling: avoiding sandals, skipping poolside barefoot moments, constantly checking if your nails look normal. Over-the-counter creams fail because they can’t reach the nail bed, and oral meds come with risks. It’s frustrating, and it chips away at your confidence.

A reliable solution
Our precision pen puts 25% undecylenic acid right where it’s needed. The brush tip paints a thin, fast-drying layer over the nail and under the edge—exactly where fungus hides. No mess, no guesswork.

Clear, resilient nails
Day by day, the discoloration fades. Nails grow back stronger, smoother, and naturally clear. By week 8, the change is visible—and the freedom to show your feet comes back without a second thought.
What to expect week by week
- Day 1Start of treatment
Begin applying to clean, dry nails. The liquid dries clear in seconds—no disruption to your day.
- Week 2Initial softening
You may notice the affected nail feels slightly softer. Discoloration might look less pronounced.
- Week 4Visible change
New nail growth near the cuticle appears clearer. Dark spots begin to recede.
- Week 8Healthy appearance
The majority of the nail looks smooth and natural. Continue treating until the entire nail has grown out.
