"Still Hiding Your Toes? This Antifungal Pen Delivers 25% Undecylenic Acid Directly Where Creams Can't Reach"

Closed-toe shoes — even in July. Socks that stay on at the beach. That instinct to tuck your feet under you when someone sits at the other end of the couch. You've been living around this problem for so long, it barely feels like a problem anymore. It's just… how things are. Yellow. Thick. Something you don't look at too closely — and definitely don't let anyone else see.

But it hasn't gone away. And quietly, in the back of your mind, you know it's getting worse.

Why a Pen Works Where Creams and Lacquers Don't

✓ Clinical-Strength Formula, No Prescription Needed 25% undecylenic acid is the highest concentration available over the counter — the same active ingredient found in professional antifungal treatments. This isn't a diluted herbal wash. It's real treatment in a pen.
✓ Targeted Delivery That Reaches the Fungus The brush-tip applicator puts the solution exactly where it needs to go — under the nail edge, along the cuticle, into the grooves where fungus hides. No mess, no waste, no guessing.
✓ Gentle Enough for Daily Use Infused with tea tree oil and calming botanicals. No burning, no stinging, no chemical odour that announces what you're treating. Just a clean, soothing application you won't dread.
✓ Simple Enough to Actually Stick With This is the part most treatments get wrong. It doesn't matter how strong a formula is if you stop using it after a week. The pen format takes under 60 seconds — twist, brush, done. That's why people actually finish the treatment.

FAQ

  • How do I get the pen to start dispensing? Twist the base of the pen clockwise. For the first use, you may need to twist several times while holding the pen tip-down until the liquid saturates the brush. This is normal — once primed, it dispenses easily with just a twist or two.

  • How long does each pen last? Each 4ml pen lasts approximately 1–2 weeks when treating multiple nails daily. For a single affected nail, a pen can last 3–4 weeks. Multi-packs provide enough supply for a sustained treatment cycle.

  • Can I wear socks right after applying? We recommend waiting 2–3 minutes for the solution to absorb. For best results, apply at bedtime and let your feet air out overnight — this also gives the formula uninterrupted time to work.
