A 100% natural rescue pen that targets stubborn fungus on contact while restoring clear, healthy nails with powerful botanical extracts.
“For best results, plan on twice-daily application for 4–6 months. Nails grow slowly, so a fungal nail needs that long to be fully replaced by clear growth. The pen format and botanical concentration make it the most realistic at-home protocol I recommend.”

In short supply — we restock weekly
Every OnyGuard Anti-Fungal Pen is filled with our 100% natural botanical formula and quality-checked in small lots, so they sell out fast.
A 100% natural botanical formula in a precision brush pen. Seven plant oils — tea tree, oregano, lavender and peppermint in a base of jojoba, grape seed and sweet almond — plus vitamins E and C, delivered exactly where you want them.
Mess-free and fast-drying. Brush onto clean, dry nails and the skin around them, morning and night. Ten seconds, then straight into socks and shoes. Works on fingernails and toenails.
Nails grow slowly, so change appears gradually as new nail grows out from the base. Plan on consistent twice-daily use over several months, and take a photo once a month so you can compare.

Used three other products before this one, and the drops always ran everywhere – I could never tell if I was hitting the right spot. This pen changed that completely. First improvement showed up in about 6 weeks, and my nail looks so much better now.
I work on my feet all day and never stayed consistent with anything before. The pen is small enough to keep in my work bag – I use it on my lunch break. No mess, no smell, no waiting room. My nail looks completely different now.
Hadn’t worn open-toe shoes in almost three years. I’m about 8 weeks in with the pen and my nail is visibly different – lighter, smoother at the base. Bought a pair of sandals last week. First time in years. That’s enough for me.

Step 1: Document your nail
Take a photo of the affected nail before you begin. Weekly comparison photos make gradual change obvious.
Step 2: Apply twice daily
Clean and dry the affected area, then apply a thin layer of the pen directly over the nail, cuticle, and edges. Morning and night, every day.
Step 3: Stick with it for 90 days
Nails grow slowly – full replacement of a damaged nail can take months. But a small difference can be seen in a month. If you fully commit to twice-daily use and don't notice small improvements in 90 days, we'll refund you.
Most people notice less itching and irritation within the first 1-2 weeks. Visible improvement in nail clarity and appearance typically shows up around weeks 8-12 with consistent twice-daily use.

OnyGuard Pen is designed to support the appearance of discolored, thickened, or damaged nails and help ease itching and discomfort. Results vary depending on how advanced the nail damage is and how consistently the pen is used.
Drops and creams flood the whole toe and often run off before they can absorb. The precision tip applies the formula exactly at the nail bed, cuticle, and edges – where fungus actually lives – without wasting product.
Every order is covered by our 90-Day Money-Back Guarantee. Document your nail, use the pen twice daily, and if you don't see a difference in 90 days, we'll refund you.
Yes. One pen covers multiple nails, so you can treat more than one nail per application if needed.
No filing required. Just clean and dry the area before applying the pen.
Nail appearance is maintained with consistent use. Once you have the look you want, many customers continue applying the pen a few times a week to help maintain results.
We recommend applying the pen to bare, polish-free nails so the formula can make full contact with the nail and cuticle.
