You're One Step Away From Clear, Healthy-Looking Nails...
The light therapy device that finally reaches the nail bed — where creams and tablets simply can't. A few minutes a day. No pills. No chemicals.

If You Want Healthier-Looking Nails... You Need Something That Can Actually Reach the Nail Bed
Here's what most people don't realise:
The problem doesn't live on the surface of your nail. It lives underneath — in the nail bed.
Your nail is basically a hard keratin shield. It's designed to protect what's underneath. That's its job.
And that's exactly why creams, oils, and topical treatments struggle to make a lasting difference.
They sit on the surface. They can't penetrate through the nail barrier. They never reach where they need to go.
You could apply cream religiously every day for a year — but if it's not reaching the nail bed, what's the point?
It's not that you weren't trying hard enough. It's that the treatments couldn't reach where they needed to go.
Luminail™ Reaches Where Creams Simply Can't
Luminail™ uses dual-wavelength light therapy — blue light (470nm) and near-infrared light (910nm).
Unlike creams that sit on the surface, light energy can actually pass through the nail to reach the nail bed area directly.
Unlike tablets, there's nothing entering your bloodstream. No chemicals. No liver concerns.
Just targeted light, delivered in minutes a day, reaching where it actually needs to go.
That's the difference. Not magic. Not miracle claims. Just basic physics.
Light penetrates. Cream doesn't.
As you use Luminail™ consistently, you're supporting your nail environment while healthy nail grows through naturally over time.
You'll finally feel confident showing your feet again. No more avoiding sandals. No more hiding at the beach.

What Our Customers Have To Say
Hear how Luminail™ is helping people feel confident again — in their own words.
Clinically Proven
Light therapy for nail fungus isn't new – it's been studied in clinical research for over a decade.
Here's what the science shows:
In a meta-analysis of 35 clinical studies involving thousands of patients, laser and light therapy achieved a 63% mycological cure rate – meaning nearly two-thirds of treated nails were completely fungus-free under lab testing.1
Multiple peer-reviewed studies found that light therapy:
- Penetrates the nail plate to reach fungal cells beneath the surface
- Increases clear, healthy nail growth in most treated patients within 6 months
- Outperforms many traditional topical treatments in head-to-head comparisons
- Works without liver or kidney side effects – no pills, no prescriptions required
Why it works: Low-level light therapy (photobiomodulation) stimulates biological activity that helps your body naturally manage fungal cells – all while avoiding systemic drug exposure entirely.
The bottom line? Light therapy has credible clinical evidence showing it can reach the infection, produce measurable nail improvement, and offer a safe alternative to oral medications.
Luminail™ Is the Safer, Healthier Choice.
Luminail™ is drug-free, works quickly, and actually helps your nails!
TREATMENT WITH LUMINAIL™
DRUG-FREE, SAFE:
Treatment with Luminail is natural and non-addictive. No pills to swallow, no chemicals to absorb.
SIMPLE DAILY ROUTINE:
Just a few minutes a day. Many users notice early signs within 2-4 weeks.
REACHES THE ROOT:
Low-dose laser therapy penetrates deep into the nail bed to destroy fungus at its source.
LONG-TERM SOLUTION:
Daily use of Luminail will completely rid you of nail fungus and help prevent it from returning.
SUPPORTED BY DERMATOLOGISTS:
"Nail-Pro is highly recommended for anyone struggling with thick, discoloured, painful or brittle nails due to nail fungus."
OTHER METHODS
DANGEROUS SIDE EFFECTS:
Prescription drugs like Terbinafine and Itraconazole can cause liver damage, heart problems, and require regular blood tests.
TAKES MONTHS TO WORK:
Prescription medications and creams take 6-12 months to show results — and often don't reach the root of the problem anyway.
SURFACE-LEVEL ONLY:
Topical creams can't penetrate the nail to reach the nail bed, so the fungus just keeps coming back.
TEMPORARY FIX:
The effect of creams and tablets ends as soon as you stop taking them, leading to constant recurrence.
DOUBTED BY DOCTORS:
GPs are increasingly sceptical of the creams and tablets they're told to prescribe — they know they rarely work.

Will Luminail™ work even for stubborn, long-term nail problems?
Will Luminail™ work even for stubborn, long-term nail problems?
Here's the honest answer:
The reason creams and topical treatments often fail to make a lasting difference is that they sit on the surface of your nail. Your nail is a hard keratin barrier — it's designed to protect what's underneath.
Luminail™ uses dual-wavelength light therapy (470nm + 910nm). Unlike creams, light energy can actually pass through the nail to reach the nail bed area directly.
That's the difference. Not magic — just physics.
However, results take time. Your toenails grow approximately 1-2mm per month. Even when Luminail™ is doing its job from day one, you need to wait for healthy nail to grow through. This typically takes months, not weeks.
The key is consistency. A few minutes a day, every day, for as long as it takes.
How long does it take to see results?
How long does it take to see results?
Let's be realistic:
Your toenails grow about 1-2mm per month. That's biology. No device, cream, or tablet can speed that up.
What most customers report:
- Weeks 2-4: Some notice early subtle signs — the problem appears to stop spreading, or a faint line of clearer nail at the base
- Months 2-3: Clearer nail becomes more visible as it grows out from the base
- Months 4-6: Healthy nail continues replacing the affected area
The timeline depends on how much of your nail is affected and how fast your nails naturally grow.
We won't promise you overnight results — because that would be dishonest. But if you stay consistent, most customers see gradual, visible improvement over time.
How long should I use Luminail™ each day?
How long should I use Luminail™ each day?
Luminail™ has 3 session settings:
- 3 minutes — Quick maintenance session
- 5 minutes — Standard daily session (most popular)
- 10 minutes — Extended session for more affected nails
Most customers start with 5 minutes daily. You can do it while watching telly, scrolling your phone, or reading.
Consistency matters more than session length. A few minutes every day is better than longer sessions you skip.
Should I use Luminail™ barefoot or with socks?
Should I use Luminail™ barefoot or with socks?
Barefoot is recommended.
For the light to reach your nails effectively, there shouldn't be any barrier between the device and your toenails.
Make sure your feet are clean and dry before each session.
What are the session time settings on Luminail™?
What are the session time settings on Luminail™?
Luminail™ has 3 pre-set time options:
- Setting 1: 3 minutes
- Setting 2: 5 minutes
- Setting 3: 10 minutes
Simply select your preferred session length and relax while the device does its work. Most customers use setting 2 (5 minutes) for their daily routine.

Does Luminail™ work on both toenails and fingernails?
Does Luminail™ work on both toenails and fingernails?
Yes, Luminail™ works on both.
However, keep in mind that toenails grow more slowly than fingernails (roughly half the speed). So if you're treating toenails, results will take longer to become visible.
The device and approach are the same — it's just biology that determines the timeline.
Is Luminail™ safe to use?
Is Luminail™ safe to use?
Luminail™ uses low-level light therapy. There's nothing entering your bloodstream — no chemicals, no pills, no drugs.
However, if you have any medical conditions (such as diabetes, circulation problems, or are pregnant), please consult your GP before using any light therapy device.
