It’s neat and fast. I do wish the pen held a bit more product, but a little goes a long way.

I’d tried three creams before this. The brush tip is genius—it gets under the edge where the problem grows.

It works, but you have to be consistent. I missed a few days and progress slowed. Stick with it!

Finally, a solution that doesn’t involve messy liquids or cotton swabs. The twist cap is great for travel.

As a swimmer, I battled fungus for years. This pen is the only thing that’s kept it in check.

QUICK START

3 minutes to healthier nails

Simple steps that fit any morning or evening routine.

1

Clean and dry

Wash the affected toe with mild soap and water, then dry thoroughly. Any moisture shields the fungus.

2

Shake and twist

Shake the pen briefly, then twist off the cap to expose the precision brush tip.

3

Brush on

Paint a thin layer over the entire nail surface and under the free edge where fungus often hides.

4

Let it dry

Wait 10 seconds until the liquid sets clear. It won’t rub off on socks or shoes.

THE SHIFT

From hiding your feet to barefoot confidence

How a targeted treatment turns a stubborn problem into a simple daily habit.

CHAPTER 01

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.

CHAPTER 02

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.

CHAPTER 03

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.

STRAIGHT TALK

Your questions, answered

Honest answers for the cautious buyer.

How long before I see results?
Visible improvement typically begins around week 4, with significant nail clearing by week 8. Consistency is key—apply daily.
Is this safe for sensitive skin?
Yes, when used as directed on nails only. Avoid contact with surrounding skin. If irritation occurs, discontinue use.
Can I use it on fingernails?
While formulated for toenails, it can be used on fingernails. The brush tip is equally precise for both.
How does undecylenic acid work?
It’s an FDA-approved OTC antifungal that disrupts the cell wall of dermatophytes, the fungi responsible for most nail infections.
Is the pen refillable?
The pen is disposable after 4ml are used. Each pen lasts approximately 30 days with daily application. Value packs are available.
What if I don’t see improvement?
If after 8 weeks of consistent daily use you see no change, check with a podiatrist. Some stubborn infections may require a combination approach.
