Lunaviatm Toenail Fungus Pen – Fast, Precise Fungus Treatment
Toenail fungus technically known as onychomycosis—is one of those conditions that many of us would prefer to ignore, but it can cause real discomfort, embarrassment and frustration when treatments drag on.
Fortunately for patients, newer options are emerging that aim to make the process easier, more convenient, and less messy.

One such option is the Lunavia™ Toenail Fungus Pen (also branded sometimes as “Lunavia Antifungal Pen”)—a pen‑style topical treatment designed for the specific challenges of nail fungus.
The Lunavia™ Toenail Fungus Pen uses 25% undecylenic acid plus botanical oils in a pen applicator to treat nail fungus precisely and mess‑free.
What is Toenail Fungus?
Toenail fungus (onychomycosis) results when fungal organisms—often dermatophytes, yeasts or molds—infect the nail plate, the nail bed underneath or the surrounding skin. The signs can include:
-
Discoloration of the nail (yellow, brown or white)
-
Thickening or distortion of the nail shape
-
Brittleness or crumbling edges
-
A foul smell sometimes
-
Possible spread to neighboring nails or skin
Risk factors include older age, diabetes or immune‑compromise, poor nail hygiene, walking barefoot in moist communal spaces (locker rooms, pool sides), tight or poorly ventilated shoes, and previous foot problems.
One of the reasons toenail fungus is notoriously difficult to treat is that the nail plate is a dense barrier, the fungus may reach the nail bed deep underneath, and recurrence is common if underlying risk factors aren’t addressed.
Why Targeted Nail Fungus Treatment is Important
General topical creams or sprays that work on the skin may not always penetrate deeply into the nail plate or reach the root of the fungal infection.
Oral antifungals exist, but they carry systemic risks (like liver side effects) and may require months of use. Meanwhile, laser treatments are expensive and not always covered or accessible.
Thus, a product like the Lunavia pen aims to deliver a targeted, user‑friendly alternative: a topical format specifically for nails and nail‑bed fungus, with convenience in mind.
If it’s used appropriately and consistently, it may reduce the fungal load, improve appearance, and help maintain nail health while addressing the underlying infection. But, as with all treatments, realistic expectations and proper foot/nail hygiene matter.
Introducing the Lunavia Toenail Fungus Pen
Lunavia Toenail Fungus Pen is marketed as a pen‑type applicator for treating nail (and sometimes skin) fungal infections—especially of the toes.
According to the brand’s own information, and several independent reviews, here are key features and claims:
Key Features & Claims:
-
The active antifungal is 25% undecylenic acid, which the manufacturer notes is the maximum strength permitted without a prescription under OTC topical antifungal monograph standards.
-
It is enhanced with botanical / plant‑based oils and materials (tea tree oil, manuka oil, clove bud oil, aloe vera, jojoba oil, propolis extract) for skin/nail‑bed support and comfort.
-
The pen format is designed for easy, mess‑free, precise application: “twist, apply, go”, with a precision applicator brush tip.
-
The company offers return/guarantee policies (for example 90‑day money‑back guarantee, free shipping on some orders) on their official site.
-
It is marketed for toe nails and sometimes fingernails, to treat discoloration, thickening, brittleness—basically the typical signs of onychomycosis.
What sets it apart:
While many antifungal nail treatments exist, the Lunavia pen claims to combine a higher strength of undecylenic acid (25%) plus a convenient pen applicator plus botanical oils for comfort. The idea is less mess, easier use, and targeted nail‑bed penetration.

How Does It Work?
Understanding how a product works can help you decide if it makes sense for your situation, and how to integrate it effectively.
Undecylenic Acid (25%):
This is a fatty acid derivative known to have antifungal activity. The manufacturer states the 25% strength is the maximum allowed without a prescription for topical OTC use.
The acid is believed to disrupt fungal cell membranes, inhibiting the growth of dermatophytes and other fungi. Because nail fungus hides under a hard nail plate, a strong penetrative antifungal agent is needed.
Botanical Oils & Supporting Ingredients:
-
Tea Tree Oil: Known for antifungal and antibacterial properties; helps reduce surface fungal load and soothe skin around the nails.
-
Manuka Oil: Another plant oil with antimicrobial/antifungal potential and soothing skin properties.
-
Clove Bud Oil, Propolis Extract: Skin‑conditioning ingredients; help with comfort during treatment.
-
Aloe Vera, Jojoba Oil, Almond Oil: Provide hydration, soften surrounding skin, reduce irritation.
Pen Applicator / Targeted Delivery:
Because nails have a thick plate and fungal infections often spread under or around the nail, the pen delivers the treatment directly to the affected nail and surrounding skin with precision.
This helps reduce wastage, avoids messy creams, and encourages consistent use. Some user reviews note the convenience.
Routine & Duration:
According to user reports and reviews, consistent application (often twice daily) is key. Improvement in appearance may begin in a few weeks (2‑6 weeks) but full resolution (new healthy nail growth) can take many months because nails grow slowly.
Strengths / Pros of the Lunavia Pen
Here are some of the major advantages noted by reviewers and manufacturers:
-
Convenience & Ease of Use: The pen format is much easier to integrate into a daily routine compared to messy creams or large jars. A reviewer noted:
“It’s portable, mess‑free, and marketed as a natural fix.”
-
High Strength OTC Antifungal: The 25% undecylenic acid is a higher than typical strength for many OTC nail treatments, increasing the potential for effectiveness.
-
Natural/Supportive Ingredients: The additional oils and skin‑care ingredients may help with comfort, reduce irritation, and support surrounding skin/nail health.
-
Precision Application: Because of the pen and brush tip, you can apply to the nail plate, nail bed exposed areas, and edges with ease, improving penetration and reducing waste.
-
Better for Mild to Moderate Cases: For early stage or less severe nail fungus, the Lunavia pen may offer a practical home treatment option.
-
Encourages Hygiene & Routine: Being easy to apply may increase adherence, which is crucial for effective treatment (no matter which product is used).
Limitations / Cons / Realistic Expectations
It’s always important to approach such treatments with realistic expectations and be aware of limitations.
-
Requires Consistency & Foot Hygiene: Treatment only works as well as the routine allows. If you keep wearing damp shoes, ignore hygiene, share nail clippers, or expose nails to fungus‑friendly environments, recurrence is likely.
-
Results May Be Cosmetic Initially: While the appearance of nails may improve (less yellowing, less thickening) within weeks, the underlying fungal load may linger and full nail replacement takes time.
How to Use the Lunavia Pen for Best Results
If you decide to use the Lunavia Toenail Fungus Pen, here are recommended steps and tips to maximise its effectiveness (adapted from available user guidelines and reviews):
Prepare the Affected Nail & Surrounding Area
-
Wash your feet and nails thoroughly with soap and water, and dry completely.
-
If safe and appropriate, gently thin the surface of the affected nail with a nail file or emery board—this helps the treatment penetrate better. Make sure to disinfect the file or use a new one to avoid spreading fungus.
-
Remove any nail polish or decorative coatings so the treatment can contact the nail surface directly.
Apply the Pen
-
As per manufacturer instructions: use clean, dry nails and surrounding skin.
-
Twist the pen base to dispense the serum onto the brush tip/applicator.
-
Apply a thin layer directly onto the affected nail(s) and the immediate surrounding skin/nail bed edges.
-
Make sure to cover the free edge of the nail tip where fungus often enters.
-
Let it dry completely before putting on socks/shoes.
Frequency & Duration
-
Many reviews indicate twice‑daily application (morning and evening) on clean, dry nails.
-
Continue even after visible signs improve—nails grow slowly and you want to treat until healthy nail fully replaces the infected portion.
-
Typical visible improvement may show in 4‑6 weeks; full nail renewal may take 3‑6 months (or more depending on nail growth rate and severity).
Complementary Foot & Nail Hygiene
-
Wear breathable shoes, alternate pairs to let them fully dry, and use moisture‑wicking socks.
-
Avoid walking barefoot in communal moist areas like showers and pool decks, or share nail tools.
-
Disinfect nail clippers/emery boards regularly and avoid re‑infection.
-
Replace old shoes or treat them with antifungal spray if fungus might be present.
-
Trim nails and keep them clean—it reduces the fungal load and allows better product access.
Monitor Progress & Be Patient
- After ~4‑6 weeks you may see less discoloration, smoother nail surface, slower thickening.
-
But do not assume cure yet—continue until the completely new healthy nail emerges and full thickness is restored.
-
If you notice worsening, spreading to more nails, pain, or possible secondary infection (swelling, redness), consult a healthcare professional.
Is the Lunavia Pen Right for You? When to Use It & When to See a Doctor
Good candidates might include
-
Individuals with early‑stage or mild toenail fungus (slight discoloration, thickening but not severe).
-
People who prefer a topical, at‑home treatment rather than oral antifungals.
-
Patients who want a convenient, mess‑free application and integrate it into their daily routine.
-
People who are willing to commit to consistent use and foot hygiene.
Situations where you should see a doctor or podiatrist instead (or in addition)
-
If the infection is severe: many nails involved, nails extremely thick/crumbling, pain, signs of spread to skin.
-
If you have underlying conditions such as diabetes, peripheral vascular disease, immune compromise, or signs of secondary bacterial infection.
-
If you have tried multiple topical treatments and no improvement; sometimes systemic therapy is required.
-
If you are pregnant or breastfeeding and unsure about topical antifungal safety (always consult your provider).
-
If you are diabetic with foot neuropathy, given increased risk of complications.
Thus, consider the Lunavia pen as part of a targeted, home‑treatment regimen—but not a substitute for professional care when the infection is advanced or you have complicating conditions.

What Do User Reviews and Independent Sources Say?
-
One user review over 2 weeks: The reviewer applied the product twice daily, saw less yellowing near the cuticle, saw nail looking healthier; however, they noted it didn’t clear all discoloration in 2 weeks, but it prevented worsening.
-
A review site noted that the pen is “easy to use, but reviews of its effectiveness are mixed, and some users report side effects.” They suggested for mild cases it might be worth a try; for severe cases prescription treatments may still be needed.
-
Another review described the pen as having “targeted, mess‑free application … visible improvements in weeks … portable and convenient.” But the review also cautioned that long‑term consistent use is key.
Key takeaways from reviews:
-
The convenience factor and ease of use are strong positives.
-
Some visible improvements can occur fairly early (weeks).
-
However, the promise of a “quick cure” may be unrealistic; monthly or multi‑month use is typical.
-
For moderate to severe fungal infections, the pen alone may not suffice.
-
Foot hygiene and consistent application significantly impact outcomes.
Tips to Maximise Your Success With the Lunavia Pen
Here are some practical tips tailored for those who plan to use the Lunavia pen and want the best possible outcome:
-
Commit to the routine: Twice‑daily application is ideal. Set reminders. Keep the pen in a visible spot (e.g., bathroom shelf) so you don’t forget.
-
Prepare nails well: Gently thin the affected nail surface (if safe) before applying so the serum penetrates better. Use a dedicated emery board only for the infected nails to avoid spread.
-
Keep feet dry and well‑ventilated: After applying the pen, avoid putting on thick non‑breathable socks immediately. Use moisture‑wicking socks and rotate shoes.
-
Use complementary antifungal foot care: Consider an antifungal spray or powder for your shoes, avoid walking barefoot in communal wet areas, and disinfect your nail tools regularly.
-
Document your progress: Take photos monthly, note changes (nail colour, thickness, content). It will help you see improvement and decide if you need additional intervention.
-
Be patient: Nail growth is slow. Even if the fungus is gone, the visible portion might still look damaged until the new healthy nail grows in. Expect months for full results.
-
Maintain post‑treatment hygiene: Once the infection appears resolved, keep the good habits to prevent recurrence: breathable shoes, clean tools, no sharing, dry feet etc.
-
Combine if needed: If you see partial improvement but still significant infection, talk to your podiatrist or dermatologist about adding an oral or professional treatment.
How Much Does It Cost & Where to Get It
According to the manufacturer’s information (as of recent data), the Lunavia pen is sold directly via the official website in the U.S., with options for one‑pack, multiple‑pack purchases, and subscriptions. Free shipping may apply for orders over a certain amounts.

Final Thoughts
If you’re dealing with nail fungus and seeking a convenient, over‑the‑counter topical treatment, the Lunavia Toenail Fungus Pen offers a thoughtful, well‑designed option: a higher‑strength antifungal ingredient (25% undecylenic acid), supportive botanical substances, a precise pen applicator, and a user‑friendly format.
For many people with mild to moderate nail fungus, especially those who want to avoid messy creams or oral medications, it may represent a practical at‑home solution.
However, it’s not a “quick fix” and works best when paired with consistent application, good foot/nail hygiene, and realistic expectations about the timeline (often several months).
If the infection is advanced, you have complicating health conditions, or you don’t see sufficient improvement after several weeks, you should consult a podiatrist or dermatologist.
