Whether you're researching NONYX as a possible toenail-fungus treatment — or you've already used it for months and are wondering why the discoloration isn't actually clearing — here's what acetic acid does to a nail (cosmetic surface cleaning), and what 200,000+ customers say happens when they switch to a 17-botanical formula built around targeting the fungus underneath.
The 60-second setup
NONYX and Orivelle aren't actually competitors in the strict sense — and that's the most important thing this page can say. They're different categories of product doing different jobs.
NONYX Nail Gel is a cosmetic. That's not editorial framing — it's the FDA classification. NONYX's active ingredient is ethanoic acid (acetic acid, the same compound found in household vinegar at higher concentration), marketed by Xenna Corporation for healthier-looking nails since 2008. The product cleans the surface of the nail, helps remove keratin debris that builds up under and around damaged nails, and softens the nail plate enough to improve cosmetic appearance. NONYX makes no antifungal claim on its label. It does not say it kills fungus. It does not say it treats onychomycosis. It does not say it prevents reinfection. It says 'for healthier-looking nails' — and that's all it's required to say, because that's all it's classified to do.
Orivelle is an OTC antifungal pen. A 17-botanical formula led by nano-formulated tea tree oil, designed specifically to maintain antifungal pressure across the 9–12 month window it takes a thick fungal toenail to grow out from the matrix. 200,000+ verified customers, 4.9★ across 5,731+ reviews, 30-day money-back direct from the manufacturer.
Below is the side-by-side breakdown podiatrists wish was visible to every patient who ever picked NONYX off the drugstore shelf hoping it would clear an actual fungal infection.
The 12-row comparison
Orivelle wins 10 of the 12 rows that decide a fungal toenail outcome. NONYX wins the two rows where it's honestly the better tool: cosmetic surface cleaning / keratin debris removal (its actual job) and same-day drugstore availability. If your goal is 'clean up the appearance of a rough nail,' NONYX wins those two. If your goal is 'kill the fungal infection in the nail and keep it dead for 9 months,' the table makes the case for the other ten.

NONYX is FDA-classified as a cosmetic. Its label says 'for healthier-looking nails' and the marketing language carefully describes what acetic acid actually does — soften keratin, remove debris, improve cosmetic appearance. It does not claim to treat, kill, or prevent fungal infection. That's not Xenna Corporation being modest. That's the legal classification.
This matters because the question most patients are actually asking when they put NONYX in their cart isn't 'will this make my nail look cosmetically cleaner?' — it's 'will this kill my toenail fungus?' And the answer to that second question is: the product makes no such claim, and the FDA classification reflects that.
Orivelle is in a different category entirely. It's an OTC antifungal product designed around 17 plant compounds led by nano-formulated tea tree oil — a compound with documented antifungal activity against the same dermatophyte strains that cause onychomycosis (Buck et al. 1994 in J Family Practice; a 2024 paper in Frontiers in Microbiology).
Same general aisle of the drugstore. Different category of product. Different job.
If your goal is cosmetic — clean the surface of a damaged nail, soften thickened keratin, improve appearance — NONYX is doing the job it was designed for. If your goal is antifungal — kill the colony, prevent reinfection, support the new nail growing in clean — NONYX isn't the tool, and a 17-botanical antifungal pen is.
NONYX's active is ethanoic acid (acetic acid). It works by softening keratin — the protein that makes nails hard — at the surface. This loosens debris that gets trapped under the nail edge, removes some discoloration that's just trapped keratin, and makes the surrounding nail look cleaner. None of this kills fungus living under the nail plate. Acetic acid at NONYX's concentration is not an antifungal at the dose required for onychomycosis.
Orivelle uses nano-formulated tea tree oil — emulsified at a particle size designed to penetrate the nail plate rather than evaporate from the surface. The pen-format precision applicator coats the nail, the cuticle, and the surrounding skin in a controlled layer that absorbs rather than runs off. The 17 supporting botanicals work as a synergistic complex around the lead tea tree active.
Different mechanism (surface keratin softening vs. nail-plate antifungal penetration). Different outcome at month nine.
The category mismatch: Acetic acid surface cleaning ≠ antifungal nail-plate penetration. NONYX is doing exactly what it's designed to do — clean keratin debris on the surface. What it's not doing is reaching the colony living under the nail plate, because that's a different product category with a different mechanism.
NONYX has been on drugstore shelves since 2008. Its reviews mostly describe what it's designed to do: 'my nails look cleaner,' 'the discoloration on the surface lifted,' 'easier to trim my nails,' 'smells like vinegar but works for cosmetic appearance.' Those reviews are accurate to the product's job.
What you don't typically see in NONYX reviews is 'this killed my toenail fungus' — because that's not the product's claim and the users who buy it for that purpose typically end up disappointed and switch to something in the actual antifungal category.
Orivelle is in the antifungal category. The manufacturer reports more than 200,000 verified customers, a 4.9-star average across 5,731+ reviews, and an 84% reported success rate from their own user data. Many users report first visible improvements within 5–7 days per the product page.
Different product category. Different review depth. Different question being answered.
Real switchers
Quotes from former NONYX customers who switched to a product in the actual antifungal category. The pattern: cosmetic improvement, fungal infection unchanged.
I'd been using NONYX nightly for four months hoping it would clear the fungus. The surface looked a little cleaner — that part was real — but the discoloration deeper in the nail wasn't moving at all. Realized after a podiatrist visit that NONYX is technically a cosmetic, not an antifungal. Switched to the 17-botanical pen and the cuticle is finally a normal color again.

Previously used: NONYX (4 months)
Was about to buy a third bottle of NONYX when I actually read the label and noticed it just says 'for healthier-looking nails' — never claims to kill fungus. Returned it, ordered the Orivelle 6-pack instead. Three months in and I can see clear new nail pushing through from the matrix.
Frank D.
Previously used: NONYX (3 months)
NONYX worked exactly as advertised — my toenails looked cosmetically cleaner after a few weeks. But the underlying fungal infection wasn't going anywhere. Switched to the actual antifungal pen and the nail is finally growing out clean instead of just looking tidier on the surface.

You asked
The objections that survive the table.
No. NONYX is FDA-classified as a cosmetic. Its label says 'for healthier-looking nails' and the active ingredient is ethanoic acid (acetic acid). The product cleans the surface of the nail and softens keratin debris but makes no claim to treat, kill, or prevent fungal infection. That's not editorial framing — it's how the product is registered with the FDA.
Acetic acid softens keratin (the hard protein in nails), which allows trapped debris under the nail edge to clear and surface discoloration in the keratin to lift. Your nail looks cosmetically cleaner — but the colony of dermatophyte fungi living under the nail plate hasn't been touched, because that requires an antifungal compound at the right dose, not a keratin softener.
That's actually a reasonable two-product approach for some patients with thick, debris-laden nails — clean cosmetically with NONYX, treat antifungally with Orivelle. But for most cases of straight fungal toenail infection, the antifungal pen alone is enough — its precision applicator and nano-formulated penetration handles the active job, and the new clean nail grows in from the matrix as the old infected one grows out.
Yes — there's no interaction or lock-in. You can stop NONYX immediately, or finish the bottle for cosmetic reasons, and start Orivelle in parallel. Most podiatrists would say the antifungal pen is the priority if there's an active infection.
Orivelle's nano-formulation is designed specifically for the penetration problem that limits topical antifungals on thick toenails. The 9–12 month grow-out is the natural matrix-to-tip cycle for any toenail — no topical accelerates it. What Orivelle is built to do is maintain consistent antifungal pressure across that full window.
Orivelle ships with a 30-day money-back guarantee direct from the manufacturer. Free shipping on all multi-pen packs. The guarantee covers the cost of the product if you're not seeing visible improvement in the first 30 days.
The verdict
The verdict on NONYX depends entirely on which job you're trying to do:
If your goal is cosmetic surface cleaning
NONYX is doing the job it was designed for. Its FDA cosmetic classification is honest about that, and at $15–$20 a bottle it's a reasonable purchase.
If your goal is killing the fungus
NONYX isn't the tool, because that isn't what it claims to do. A product in the antifungal category is what's designed for that job.
If you've already used NONYX for 60+ days
And the surface looks cleaner but the discoloration deeper in didn't move — switch to a multi-botanical antifungal pen designed for nail-plate penetration.
If your goal is antifungal — you have an actual fungal infection in the nail that you want to kill and keep dead for the 9 months it takes the new nail to grow out — NONYX isn't the tool, because that isn't what it claims to do. A product in the antifungal category — a multi-compound formula designed around penetrating the nail plate and maintaining antifungal pressure across the full grow-out window — is what gives you a realistic shot at clearing the infection.

For most patients I see who've already used NONYX hoping it would clear a fungal infection, I'd suggest the 6-pack. Per-pen price drops to $9.99 — within the same range as a NONYX bottle — and you have enough pens to run consistently for the 9 to 12 months a thick fungal toenail needs to fully grow out from the matrix.
