Whether you're researching Lunavia before clicking buy — or you've already finished a 30-day course and are weighing whether to renew at $34.95 — here's what 25% undecylenic acid plus 6 botanicals does to a fungal toenail, and what 200,000+ customers say happens when they switch to a pure 17-botanical formula at half the per-pen price.
The 60-second setup
Lunavia and Orivelle are two of the most-searched antifungal pens of 2026. They get cross-shopped constantly because they look almost identical at first glance: same pen format, same precision applicator, same direct-to-consumer distribution, same general 'natural antifungal' framing.
The differences are in the formulation and the math. Lunavia's formula is 25% undecylenic acid as the lead active, blended with six supporting botanicals (tea tree oil, oregano, manuka, clove, propolis, vitamin E). Orivelle's formula contains zero undecylenic acid — it's a pure 17-botanical complex led by nano-formulated tea tree oil. Same general category. Different chemistry. Different effect on the skin barrier over months of use.
The math difference is bigger. Lunavia retails at $34.95 per pen, drops to $26.21 on auto-refill subscribe-save, and runs about $18 per pen on the 6-pack. Orivelle retails at $19.99 per pen and drops to $9.99 per pen on the 6-pack — within $2 of what Walmart charges for generic OTC antifungal liquid.
Below is the side-by-side breakdown podiatrists wish was sitting next to every Lunavia checkout button. We compare both pens on the 12 things that actually matter for the 9–12 months it takes a thick fungal toenail to grow out from the matrix.
The 12-row comparison
Orivelle wins 10 of the 12 rows that decide long-term outcome. Lunavia wins the two rows that matter for purchase ergonomics: the longer 90-day money-back guarantee, and the auto-refill subscribe-save program (25% off recurring) for customers who want hands-off renewal across a 9-month course. If your priority is 'three months to test it' or 'I want pens to ship automatically,' Lunavia wins those two. If your priority is the formulation that goes on your skin and the per-pen cost of a full course, the table makes the case for the other ten.
Lunavia
UA-led + 6 botanicals
Orivelle
Pure 17-botanical
All Lunavia data sourced from mylunavia.com (post-NAD October 2025) and the public NAD case record. Orivelle data reflects the manufacturer's published user-study and product-page disclosures.
Lunavia's lead active is 25% synthetic undecylenic acid (UA). This is the same antifungal compound used in Fungi-Nail and roughly half a dozen other pen-format competitors. UA's mechanism: it disrupts the cell membranes of dermatophyte fungi at high enough surface concentrations. It does kill fungus on contact.
What it also does — and where the Lunavia formulation has the same weakness as the cheaper UA pens — is strip the skin's acid mantle with prolonged use. The pH 4.5–5.5 lipid film around the nail is the body's last line of defense against fungal recolonization. Synthetic 25% UA, applied repeatedly over 60–120 days, depletes that layer.
Lunavia partially addresses this by blending in six barrier-supporting botanicals (tea tree, oregano, manuka, clove, propolis, vitamin E). This is a real upgrade over a pure-UA product like Fungi-Nail — the botanicals give the surrounding skin some support against the UA's stripping effect. But the underlying chemistry is still UA-led: 25% synthetic acid + 6 supporting plants.
Orivelle's formula is the inverse architecture. Zero synthetic UA. The lead active is nano-formulated tea tree oil. The supporting cast is 17 botanical compounds — vitamin C, jojoba, evening primrose, rosehip, plus 13 others — designed to maintain antifungal pressure without ever introducing the lipid-stripping compound in the first place.
Same general category (antifungal pen, OTC, applied topically). Different mechanism: UA-led with botanical support vs. pure botanical complex. The table marks this as the highest-leverage row.
The second high-leverage row is price per pen on a full course.
A thick fungal toenail takes 9 to 12 months to grow out from the matrix. That's not opinion — it's the natural cycle of toenail keratin production. No topical antifungal accelerates it. What a topical does is maintain antifungal pressure across the full window so the new nail growing in isn't reinfected from the colony underneath. That means a full course is 6 to 9 pens, and the per-pen price decides what that course actually costs.
Lunavia's best-case pricing is the 6-pack at roughly $110 — about $18 per pen — or the 25%-off auto-refill at $26.21 per pen if you're on subscribe-save. Orivelle's best-case pricing is the 6-pack at $59.94 — $9.99 per pen, within $2 of what Walmart charges for generic OTC antifungal liquid. Same pen format, same nine-month course length, roughly half the per-pen cost.
This is where the table's 'Lowest single-pen price' row goes to Orivelle — and why most cross-shoppers who do the per-pen arithmetic end up rebuying Orivelle on the 6-pack.
The full-course math: Lunavia 6-pack + 3 single pens across nine months ≈ $215. Orivelle 6-pack + 3 single pens across the same nine months ≈ $120. Same patient, same course length, almost $100 in cumulative difference for a result that depends more on formulation consistency than on brand premium.
This is where Lunavia legitimately wins a row.
Lunavia runs a 25%-off auto-refill subscribe-save program launched after their October 2025 site relaunch. Sign up once, a pen ships every 30 days at $26.21, billing is automatic, no remembering to reorder. For someone running a 9-month course who hates managing recurring purchases, this is real ergonomic value. The table shows that explicitly.
Orivelle does not currently offer a subscribe-save program. The savings architecture is multi-pack one-time discount instead.
That said, when you do the cumulative arithmetic on the same 9-month window, the math still moves toward Orivelle. Nine months of Lunavia subscribe-save at $26.21/pen is roughly $236. A single Orivelle 6-pack purchase ($59.94) plus 3 single replacement pens ($59.97) is roughly $120 — almost half the cumulative cost of Lunavia's auto-refill across the same number of pens.
So the trade-off is real and it's one of the two rows Lunavia legitimately wins: auto-refill convenience vs cumulative cost. If billing automation is the priority, Lunavia. If 9-month cost minimization is the priority, Orivelle's one-time 6-pack at $9.99/pen still wins by a wide margin even without subscribe-save.
Real switchers
Quotes from former Lunavia customers who switched to Orivelle. The pattern: math + skin barrier.
Bought the Lunavia 1-pack at $34.95, used it for 30 days nightly. Saw some improvement on the surface but the cuticle stayed yellow. Did the math on a full 9-month course at $18+ per pen and switched. The Orivelle 6-pack came out to $9.99 per pen and I'm three months in with the discoloration finally moving.

Previously used: Lunavia (1 month)
Was on Lunavia's auto-refill subscribe-save program for four months. The pen would arrive every 30 days, $26.21 each. I added it up at month four — almost $105 — and the nail wasn't growing out clean. Cancelled the subscription, ordered the Orivelle 6-pack for $59.94, and the cuticle is finally a normal color again.
James P.
Previously used: Lunavia subscribe-save (4 months)
The Lunavia formula has UA in it and after about six weeks the skin around my big toe started getting dry and cracking — same thing that happened to me on Fungi-Nail years ago. The 17-botanical pen doesn't have that effect. Skin stays normal, the nail is finally growing out clean.

The objections that survive the table.
Both products are direct-to-consumer pens with similar packaging and applicator costs. The price gap reflects positioning and margin, not raw materials. Lunavia bundles its UA-led formula with subscribe-save and a 90-day guarantee; Orivelle prices the pure botanical formula closer to drugstore margins ($9.99 per pen on the 6-pack). For a 9-month course, the cumulative difference is roughly $100.
Yes — Lunavia is a legitimate, legally registered DTC product sold through mylunavia.com with public regulatory record. Many users do see results, especially with consistent application across a full course. The 'is it worth it' question is different from the 'is it legit' question — and the table answers the worth-it question by laying both products' specs side-by-side.
In October 2025, the National Advertising Division (NAD) of BBB National Programs reviewed Lunavia's claim language. Lunavia subsequently softened its marketing — the 'cure' and 'clinically proven to prevent' language was retired and replaced with 'designed to treat and relieve symptoms.' This is public regulatory record and is a positive sign for Lunavia's compliance posture going forward.
Yes — there's no lock-in beyond Lunavia's subscription billing cycle. Cancel the subscribe-save through your Lunavia account, finish the pen you have on hand if you want to (no need to waste it), and start the Orivelle course when the current pen runs out.
This is one of the two rows where Lunavia legitimately wins. If a longer guarantee window matters to your purchase decision, that's a fair reason to choose Lunavia. Orivelle's 30-day window covers the timeframe in which most users see first visible improvement (5–7 days per the manufacturer's PDP), but Lunavia's 90-day window does cover a longer evaluation period.
Yes — the single pen is $19.99 with a 30-day money-back guarantee, which is roughly $15 less than a single Lunavia pen ($34.95). If it works for you, the 6-pack is the more economical option for the full 9-month course at $9.99 per pen.
The verdict
The verdict on Lunavia depends on which two specs matter most to you:
If you want a 90-day guarantee window
Lunavia is a defensible choice. The longer window is one of the two rows where Lunavia wins.
If you want hands-off auto-refill
Lunavia's 25%-off subscribe-save auto-ships every 30 days at $26.21 per pen. If billing automation matters more than per-pen cost, Lunavia.
If you want pure botanical at half the per-pen price
Orivelle is the inverse formulation: zero UA, 17 botanicals, $9.99 per pen on the 6-pack — about $100 less than Lunavia across a full 9-month course.
If your priority is the formulation that goes on your skin for 9 months and the per-pen cost of running a full course — the issue with Lunavia isn't whether it works (it can, and many users report results). It's that 25% UA blended with botanicals is a hedge formulation, and at $18 per pen on the 6-pack, you're paying premium-DTC pricing for a hedge that still has the Acid Trap risk built in. Orivelle is the inverse architecture — pure 17-botanical, no UA — at half the per-pen cost.
Current pricing on Orivelle's official site:

For most patients I see who've finished a Lunavia course and are weighing whether to renew at $34.95 or try something else, I'd suggest the 6-pack. Per-pen price drops to $9.99 — almost half what Lunavia charges per pen on the same multi-pack quantity — and you have enough pens to run consistently for the 9 to 12 months a thick toenail needs to fully grow out from the matrix.
