What is Fungabeam?
Fungabeam is a rechargeable, at-home light device marketed for nail clarity, strength and healthier-looking toenails with seven-minute daily sessions.
The Fungabeam toenail device review covers the Fungabeam rechargeable light device, so confirm which product a listing is for.
Does Fungabeam really work?
The seller markets Fungabeam for nail clarity and strength, so the fair test is the research on the nail fungus options it sits beside. The studies below tested lasers, not this device.
Nail fungus is slow to clear. The American Academy of Dermatology says nail fungus almost never goes away on its own, and a clear nail has to grow out, which takes months. On the big toe, it may take a year or longer. WebMD gives a similar window, saying a toenail may take 12 to 18 months to grow out.
What the laser studies found
Laser research is the closest match to the nail devices shoppers compare with Fungabeam, so it is the most useful body of research to read. How meta-analyses combine studies (our research library) explains how the pooled reviews below work.
| Study | What it looked at | What it found |
|---|---|---|
| Ma et al., 2019 systematic review and meta-analysis | 35 articles covering 1,723 patients | Mycological cure (negative fungal test) of 63.0% overall, 74.0% with CO2 lasers and 63.0% with 1064-nm Nd:YAG lasers, with wide ranges. The authors describe laser treatment as relatively safe, with tolerable pain and occasional bleeding. |
| Yeung et al., 2019 systematic review of prospective trials | 22 prospective trials with 755 participants | Mycological cure 70.4%, clinical improvement 67.2%, and complete cure 7.2%. The authors call the evidence limited and highly variable. |
| LASER-1 randomized sham-controlled trial, 2019 | A randomized, quadruple-blind, sham-controlled trial of laser for onychomycosis in people with diabetes at risk for foot ulcers | Published in the Journal of the European Academy of Dermatology and Venereology, 2019. |
| Gupta et al., 2022 systematic review of laser trials | Randomized trials of laser alone for toenail fungus | No study reported a complete cure. Clinical cure ranged from 13.0% to 16.7% for short-pulsed lasers and was 25.9% for long-pulsed lasers. |
| Zhang et al., 2022 meta-analysis of laser plus topical antifungal | A meta-analysis of randomized trials of laser combined with topical antifungals | Published in Lasers in Medical Science, 2022. |
| Zang et al., 2017 retrospective study | A retrospective study of non-thermal laser therapy for toenail onychomycosis; not Fungabeam | One author is employed by Erchonia Corporation, which sponsored the study. |
Read the pattern: several reviews report that many nails or participants improved or tested clear in some trials, but full cures are rare and the trials differ widely. Yeung and colleagues call the evidence limited. WebMD says studies of laser treatment are mixed, and reports that the American Academy of Dermatology says more research is needed to know whether lasers are safe and effective.
If the goal is clearing an infection, the American Academy of Dermatology says prescription medication is necessary, and MedlinePlus says lasers are less effective than medicines. Laser evidence is limited, and Fungabeam was not studied.
Is Fungabeam legit?
The seller is listed as FungaBeam, reachable at support@fungabeam.com or +1 (888) 264-0609. This site has not bought or tested the device, and the seller's site could not be checked, so verify the seller, specifications and terms yourself.
Before paying, check four things: the seller name on the product page, the device specifications, the total at checkout and the written return terms. Save the product page and your order confirmation so you have a record.
What is in Fungabeam, and is it undecylenic acid?
Fungabeam is marketed as a light device rather than a liquid, so the seller's specifications and instructions are the place to check what you are buying. The basics are:
| Item | Detail |
|---|---|
| Form | Portable, cordless, rechargeable light device |
| Where it goes | Fingernails and toenails |
| Session | Seven minutes daily |
| Marketed for | Nail clarity, strength and healthier-looking toenails |
| What to check with the seller | Specifications, charging method, safety directions and return terms |
Undecylenic acid is a common question for topical nail products. Drugs.com lists undecylenic acid topical products for skin infections such as athlete's foot, jock itch and ringworm, and says to use only the formulation made for the body area you are treating. Fungabeam is marketed as a light device, so ask the seller for its specifications rather than assuming it contains any topical ingredient.
Side effects and when to see a clinician first
Check the label and ask a pharmacist or clinician before use, especially during pregnancy or breastfeeding or before using it on a child. Ask FungaBeam for the safety instructions before you order.
Nail fungus carries its own risks, separate from any product. MedlinePlus lists diabetes, peripheral vascular disease, immune system problems and minor skin or nail injuries as risk factors for a fungal nail infection. It says to contact your provider if the infection does not go away, or if the area becomes painful, red, or drains pus. Cleveland Clinic lists cellulitis in the surrounding tissue among nail fungus complications.
Scripps quotes Stacie Ly, MD, saying that if symptoms are severe or painful, or the toenail turns brown or black, it is best to see a primary care doctor or podiatrist instead of treating it yourself. The Scripps guide to toenail fungus treatments carries that advice. The American Academy of Dermatology adds that if pain or trouble walking or standing develops, proper treatment is important.
MedlinePlus notes that subungual melanoma, a potentially deadly cancer, normally appears as a dark streak down the length of the nail. A new dark streak is a reason for a clinician's look, not a home device.
What does Fungabeam cost, and how do refunds work?
Prices and package options change, so check today's price directly with FungaBeam on the Product Page. A May 23, 2025 third-party press release listed $89.99 for one device, $80.99 each for two, $71.99 each for three and $62.99 each for four. The seller's site could not be checked, so confirm the quantity, shipping, tax and final total on the checkout screen before you pay. Ask whether the order sets up any repeat charge, and save the confirmation.
The press release lists a 30-day money-back guarantee and says shipping and handling are deducted from a refund. Ask the seller for its return terms in writing before you order, including the return window, who pays return shipping and whether any charge is non-refundable. Keep the package, order number and tracking receipt until any refund is complete.
Could I just use a home remedy or a prescription instead?
The options differ in what the research shows and in how much work they take. The table puts them side by side.
| Option | What the sources say | What to know |
|---|---|---|
| Fungabeam | The seller markets a rechargeable light device for nail clarity and strength | Check the total price and return terms; the studies here do not test it |
| Oral antifungal pills | WebMD says antifungal pills such as itraconazole and terbinafine work better than creams and gels, and that a doctor needs to monitor you while you take them | Usually about 12 weeks; the fungus may not be fully gone for 10 months or longer |
| Prescription nail creams and gels | WebMD says ciclopirox, efinaconazole and tavaborole are best for surface fungus because they do not penetrate the nail bed well | May take a year of daily use; a podiatrist may trim and file the nail first |
| Clinic laser | Yeung et al. call the evidence limited; MedlinePlus says lasers may sometimes clear the fungus and are less effective than medicines | WebMD says treatments take about 30 minutes, usually two or more 5 to 6 weeks apart, and are not covered by insurance |
| Nail removal | WebMD says a doctor may remove all or part of the nail when the infection is deep and long-standing | A new nail usually grows back, but it may take a year or so |
If you are also weighing another at-home device, the SUWU nail fungus light device review covers a different product. Our guide to nail fungus cream explains why most nail fungus creams are made for skin and what to check on a product label.
Oral terbinafine: side effects, course length and Lamisil questions
What are the potential side effects of taking oral terbinafine?
Cleveland Clinic lists the following for terbinafine tablets. WebMD adds that the pills can cause nausea, vomiting and headaches.
| Group | Examples from Cleveland Clinic |
|---|---|
| Report to your care team as soon as possible | Allergic reactions such as rash, hives or facial swelling; liver injury such as upper belly pain, dark urine or yellow skin or eyes; severe skin reactions with fever, blisters or peeling; lupus-like symptoms; low red blood cell level; unusual bruising or bleeding; change in taste or smell; signs of infection; worsening mood |
| Often reported, usually less serious | Diarrhea, gas, headache, nausea, stomach pain and upset stomach |
| Other precautions | Sun sensitivity: keep out of the sun, wear protective clothing and sunscreen, and avoid tanning beds |
| Interactions | Do not take with pimozide or thioridazine; may interact with beta blockers, warfarin, cyclosporine, rifampin and others |
Is 6 weeks of terbinafine enough for toenail fungus?
MedlinePlus says toenails usually need about 2 to 3 months of oral antifungal medicine, and WebMD says the usual course is 12 weeks, with the fungus possibly not fully gone for 10 months or longer. Six weeks is shorter than both. How long your course should run is a decision for the prescriber who monitors you, so ask them directly how long the course should last and when your liver will be checked.
Why does it say not to use Lamisil on nails?
WebMD lists terbinafine (Lamisil) cream as an over-the-counter option for mild toenail fungus, says most OTC products are not strong enough for moderate or severe cases, and says terbinafine pills need a prescription. Follow the label on your specific product and ask a pharmacist or prescriber which form is right for your nail.
Home remedies and the permanent fix
Does Vicks VapoRub work on toenail fungus?
Scripps says a very small study found this mentholated ointment had a positive effect on toenail fungus. MedlinePlus says over-the-counter creams and ointments usually do not help treat this condition.
How long does Vicks VapoRub take to work?
Scripps says home treatments may need to be applied several times daily for six months or more. Even then, a nail takes 12 to 18 months to grow out, according to WebMD.
Does hydrogen peroxide get rid of toenail fungus?
Scripps says vinegar and hydrogen peroxide are popular home remedies but have not been shown to be effective in clinical studies.
| Home remedy | What the sources say |
|---|---|
| Vicks VapoRub | A very small study found a positive effect on toenail fungus |
| Vinegar or hydrogen peroxide | Popular, but not shown effective in clinical studies |
| Tea tree or eucalyptus oil | Studies found they performed as well as some over-the-counter and prescription topical treatments |
| Baking soda | Researchers found baking soda prevented fungal growth in 79 percent of the specimens tested |
Those figures come from Scripps, which also says the remedies are for early-stage fungus. If symptoms are severe, painful, or the toenail turns brown or black, see a primary care doctor or podiatrist rather than treating it yourself.
Is there one treatment that permanently clears nail fungus?
No product is shown to kill nail fungus permanently. Sources describe prescription medicines as more effective than creams and lasers, but even they do not always clear the fungus or prevent recurrence. MedlinePlus says medicines clear the fungus in about one half of the people who try them, and that even when treatment works, the fungus may return. Scripps puts recurrence as high as 40 percent.
Do remedies from the Amish or Japan work any better?
The origin of a remedy does not tell you whether it works. Judge any folk remedy by the same tests: whether a study found it works, and whether it fits your nail's situation.
What causes nail fungus, and who should look at it?
What causes nail fungus?
The American Academy of Dermatology says dirty nails alone cannot cause nail fungus. The fungi must get into the nail or a small opening in the skin around it, and they can spread from athlete's foot, shared clippers and damp floors. Cleveland Clinic says dermatophytes cause at least half of all nail fungus cases, and molds account for about 1 in 10.
Is toenail fungus a dermatology issue?
Yes. The American Academy of Dermatology says a dermatologist knows how to treat nail fungus, even stubborn cases, and that dermatologists have expertise in diagnosing and treating nail conditions.
What type of doctor is best for toenail fungus?
The right doctor depends on how severe the problem is. Scripps names a primary care doctor or a podiatrist for severe, painful or dark nails, and for fungus that keeps coming back. The American Academy of Dermatology names a dermatologist, who treats both skin and nails.
How can nail fungus be treated?
Cleveland Clinic lists medications taken by mouth or applied to the nail. WebMD and MedlinePlus add that the nail is sometimes removed. MedlinePlus says over-the-counter creams usually do not help, and that prescription oral medicines may help clear the fungus. Cleveland Clinic says lab testing is essential for confirming the diagnosis and identifying the type of fungus.
What does FDA clearance mean for a nail-fungus laser?
What is a 510(k) premarket notification?
The FDA's 510(k) page says a 510(k) is a premarket submission that shows a device is substantially equivalent to a legally marketed device. FDA's order that finds it substantially equivalent is what clears the device for sale.
When should a 510(k) premarket notification be submitted?
FDA says anyone who wants to sell a device in the U.S. must make a 510(k) submission at least 90 days before offering it for sale, unless the device is exempt. Until FDA finds the device substantially equivalent, the submitter may not market it.
Which devices are exempt from a 510(k), and what does exempt mean?
FDA says certain Class I and II devices can be marketed for the first time without a 510(k) when exempt by regulation (21 CFR 862 to 892). FDA keeps a list titled Medical Device Exemptions 510(k) and GMP Requirements. Exempt means the device can be sold without a 510(k), as long as it stays within the exemption's limits.
Where can I find the FDA premarket approval database?
Search 510(k) records in FDA's 510(k) Premarket Notification database. FDA's Databases menu on that site also lists Premarket Approvals (PMAs).
FDA's 510(k) database files nail-fungus lasers under the device category ‘Lasers For Temporary Increase Of Clear Nail In Patients With Onychomycosis' (product code PDZ, regulation 21 CFR 878.4810). One example is Erchonia's LunulaLaser, K153164, found ‘Substantially Equivalent' on 06/03/2016 (record K153164). A 510(k) clearance is not an FDA approval, and the category describes a temporary increase in clear nail, not a cure. If a seller says ‘FDA cleared', ask for the 510(k) number and search it in FDA's Premarket Notification database.
If you are looking at a home laser or light device, confirm the wavelength, power, nails per session and kit contents with the seller before purchase.
Before you order
- Confirm which product a listing is for, since Fungabeam is a light device and other laser or light devices are different products.
- Ask FungaBeam for the specifications, charging method and safety directions.
- Check the total on the checkout screen, including shipping, tax and any repeat charge.
- Get the return terms in writing, including the shipping and handling deduction, and save the order confirmation.
- See a clinician if the nail is painful, spreading, brown or black, or if you have diabetes or a weakened immune system.
