Fungal Nail Laser Erchonia®
What Is Fungal Nail Infection (Onychomycosis)?
Fungal nail infection, clinically referred to as onychomycosis, is a common condition that affects both the toenails and fingernails. It develops when fungal organisms, most commonly dermatophytes, invade the nail bed and surrounding tissue — often causing thickening, discolouration, and brittleness of the nail.

Onychomycosis is classified as a mycotic nail disease and accounts for over 50% of all nail-related disorders seen in podiatric clinics. It is particularly prevalent among individuals who:
- Use communal facilities such as swimming pools or gyms
- Wear tight or non-breathable footwear
- Suffer from diabetes, poor circulation, or have a compromised immune system
Fungi thrive in warm, moist environments — making the toenails a common site of infection due to prolonged exposure to closed shoes and humid conditions.
Common Signs and Symptoms
The symptoms of a fungal nail infection typically develop gradually and may vary in severity. Key indicators include:
- Yellow, white, or brown nail discolouration
- Thickened, brittle, or crumbly nails
- Flaky debris or foul smell under the nail
- Nail lifting or separating from the nail bed
- Discomfort when walking or wearing closed footwear
In some cases, the condition may also affect the skin around the nail or co-exist with athlete’s foot (tinea pedis).
What Causes Fungal Nail Infections?
Fungal nail infections are primarily caused by:
- Dermatophytes – fungi that digest keratin in nails
- Yeasts such as Candida albicans
- Non-dermatophyte moulds – environmental fungi that penetrate damaged nails
These infections often result from:
- Direct contact with contaminated surfaces
- Nail trauma or repetitive pressure
- Pre-existing fungal infections of the skin
- Medical conditions such as diabetes or immunosuppression
Why Are Fungal Nail Infections Hard to Treat?
Onychomycosis is notoriously difficult to eradicate due to several compounding factors:
- Topical antifungal treatments often cannot penetrate the full thickness of the nail
- Oral antifungal medications may require long-term use and carry potential liver-related side effects
- Fungal spores may persist in shoes, socks, or nail tools, leading to reinfection
- Nail growth is slow, meaning visual improvements take months even after treatment begins
Topical antifungal agents frequently fail to cure onychomycosis, largely because their active ingredients are unable to permeate the full thickness of the diseased nail plate and reach the fungal organisms in deeper layers, a limitation established in clinical reviews of treatment failure by Xia, X., et al.
These challenges often lead patients to explore alternative, more effective treatments — such as the Erchonia Lunula Laser, which is designed to target fungal pathogens directly, stimulate clear nail regrowth, and deliver results without medication or pain.
The Erchonia Lunula Laser: A Breakthrough Cold Laser Therapy
The Erchonia® Lunula Laser represents a clinically advanced, MHRA-registered cold laser therapy designed to safely and effectively treat fungal nail infections, also known as onychomycosis. Unlike traditional methods such as oral antifungal medications or heat-based lasers, the Lunula Laser offers a pain-free, non-invasive solution with no downtime and no side effects.
This cutting-edge device is widely used across UK podiatry clinics and is administered by HCPC-registered podiatrists as part of a regulated and results-focused treatment plan.
The Lunula Laser uses a non-thermal, dual-wavelength low-level laser approach, and retrospective clinical data—including analysis by Zang, Sullivan, and Shanks—show that about 67 % of treated toenails achieved ≥3 mm of new clear growth at six months with no reported adverse events, supporting both its efficacy and safety profile.
How the Lunula Laser Works
The Lunula Laser utilises Low-Level Laser Therapy (LLLT) — also known as photobiomodulation — to stimulate healing and eliminate fungal infection at the source. It operates using two distinct wavelengths of low-level light:
- 405 nm (Violet): Antifungal action — disrupts the cellular integrity of fungal organisms
- 635 nm (Red): Biostimulatory — enhances circulation, promotes immune response, and accelerates nail regeneration
Together, this dual-wavelength approach delivers a synergistic treatment: targeting the fungal infection while stimulating the body’s natural healing mechanisms.
MHRA Registration & UK Clinical Safety
The Lunula Laser is a MHRA-registered medical device, approved for use in the treatment of onychomycosis in clinical settings across the UK. This registration confirms the device meets strict UK safety and performance standards, offering patients peace of mind regarding its use.
- Clinically tested
- Registered with the Medicines and Healthcare products Regulatory Agency (MHRA)
- Delivered by regulated healthcare professionals
Clinical Benefits of Cold Laser Therapy
Unlike heat-based lasers, which can cause discomfort or even burns, the Lunula is a cold laser — meaning:
- No pain, no heat, and no risk of skin damage
- No anaesthetic or nail removal required
- No post-treatment restrictions — you can resume daily activities immediately
For background on causes, symptoms, and testing, see our detailed fungal nail infection overview.

Why Choose Laser Therapy Over Traditional Treatments
When managing fungal nail infections (onychomycosis), patients are often left frustrated by the limitations of traditional treatments. Topical antifungal creams may lack potency, oral medications carry systemic risks, and heat-based laser therapies can cause discomfort or skin damage.
The Erchonia® Lunula Laser, by contrast, is a MHRA-registered cold laser therapy that is pain-free, non-invasive, and proven effective — offering a better way forward for those seeking lasting results without compromise.
Additional guidance on managing fungal and non-fungal nail problems can be found in our podiatry care for skin and nail conditions section.
Understanding the Limitations of Traditional Treatments
Topical Antifungal Creams
These are typically the first treatment patients try — but they often underperform due to:
- Poor nail penetration capabilities
- Long treatment times (up to 12 months)
- Daily maintenance burden with low success rates
Oral Antifungal Medication
Systemic treatments such as terbinafine and itraconazole are more potent but come with:
- Liver toxicity risks and potential side effects
- Drug interactions, especially for older patients
- Need for blood tests and medical monitoring
- Contraindications for those with liver disease or pregnancy
Heat-Based Laser Devices
While more advanced, traditional hot lasers are not without issues:
- Can cause burning or discomfort
- May require anaesthetic or recovery time
- Lack the biostimulatory benefits offered by cold laser devices

Will the Treatment Hurt?
No — the Lunula Laser is 100% pain-free. It uses cold laser light at two wavelengths to treat the infection and stimulate natural nail growth, without any sensation of heat, vibration, or discomfort.
Most patients describe the session as completely passive — simply sit back and relax for 12 minutes per foot or hand.
How Soon Will I See Results?
Visible results vary depending on nail growth rate and severity of infection, but most patients see:
- Initial signs of improvement within 8–12 weeks
- Noticeable clearing and healthy nail regrowth within 3–6 months
Toenails grow slowly, so full nail replacement may take 6–12 months depending on the individual.
How Many Sessions Will I Need?
The standard protocol includes a course of four laser sessions, typically spaced 7 days apart. This is often sufficient for mild to moderate infections.
Severe or multi-nail infections may require additional sessions, which your podiatrist will advise on during your consultation.
Each session is brief — around 12 minutes — and requires no downtime.
Do I Need to Follow Aftercare Steps?
Yes — proper aftercare is crucial to maintain treatment results and prevent reinfection.
Your podiatrist will provide a tailored home hygiene protocol, including:
- Daily foot and shoe hygiene practices
- Antifungal product recommendations (e.g. sprays, socks, powders)
- How to disinfect footwear, nail tools, and shared surfaces
