I tested the most-bought nail fungus pens of 2026 — one clearly stood out
Over the past two months I put more than 30 nail fungus pens sold across the UK through real, hands-on use. Only a handful delivered — and one left every other brand behind.
Nail fungus is one of those problems people deal with quietly. Nails turn yellow, thick and brittle, and suddenly you're hiding your feet in socks all summer. The frustrating part? Most "solutions" barely do anything.
Creams sit on top of the nail and never reach where it matters. Tablets come with a list of side effects long enough to put anyone off. Laser clinics can run well over £1,000. So it's no surprise the pen format has taken over — a slim brush-tip applicator you swipe on twice a day. No mess, no fuss, discreet.
But one question keeps coming up: does it actually work, or is it just clever marketing? The honest answer depends entirely on which pen you buy. The differences between brands are huge — same price, completely different formula.
- Quality & number of active botanical ingredients
- Brush-tip precision & how well it reaches the nail edges
- Skin comfort, dry time and residue
- Price per application & current discount
- Real user experience over weeks of use
👉 One product pulled clearly ahead. Here's the breakdown.

See the winner →Why most nail fungus pens disappoint
The UK has dozens of pens on the shelves — in our testing, the large majority failed for the same four reasons.
- ✕Filler-heavy formulas. The label lists botanicals — but the active ingredients are barely there, too diluted to do much for the look of your nails.
- ✕Label ≠ contents. More than once, what was inside didn't match what the front of the pen promised.
- ✕A cheap brush. A wide, sloppy tip drips and wastes the solution instead of placing it precisely on the nail.
- ✕One single ingredient. Instead of a considered blend, many rely on a single oil — and hope the marketing does the rest.
Of every pen we tested, only three delivered what they promised. Those are the three above — and at the very top sits the only one that impressed in every category.
A word from me — why only three?
A fair question. What surprised me most: the majority simply didn't contain the botanicals the label promised — barely-there blends, missing ingredients, formulas you'd struggle to tell apart from water.
And if you ask me personally which pen I'd reach for tomorrow morning? Orivelle. Without hesitation. It's the cleanest formula in the comparison, the most thought-through blend, and the only one currently available at a price most readers can actually justify.
Why the Orivelle pen takes #1
#1 · Editor's Choice
/10
Across the most-searched nail fungus pens, the Orivelle pen came out ahead in every category that counts. The slim brush-tip applicator places the solution exactly where creams and drops can't reach — along the nail edges, into the cuticle and around the nail bed.
A considered 17-ingredient botanical blend
Rather than a single oil, Orivelle leans on a blend of plant-based ingredients widely used in natural nail care:
The nourishing oils are designed to address the look of discolouration, brittleness and rough texture as the nail grows out — while the precise brush keeps every drop where you want it.

Individual experiences. Results can vary and are neither typical nor guaranteed.
"I'd tried creams for months with nothing to show for it. The brush is the bit that won me over — it actually gets right into the edges. Three weeks in and I'm finally not embarrassed to wear sandals."
Manchester
"Sceptical at first, I'll admit. But it dries in seconds, there's no greasy mess and I can pop it in my bag. Easiest thing I've added to my routine in ages."
Bristol
"Lovely and simple — brush on twice a day and that's it. I like how discreet it is. Curious to see how my nails look after a couple of months, but I'm pleased so far."
