Why light therapy works where creams can't.

The research behind CleraVita isn't new. Blue light phototherapy for nail fungus has been studied in clinical settings for over a decade. What's new is making it accessible at home.

The core problem

Your nail is a barrier. That's the point.

The nail plate is made of keratin, the same tough protein in hair and animal horns. It's designed to protect the nail bed underneath. That's exactly what it does when you apply cream, oil, or any topical treatment. It blocks it.

Nail fungus (onychomycosis) lives under this barrier, in the nail bed and within the nail plate itself. Topical antifungals have a fundamental delivery problem: the molecules are too large to pass through the keratin structure in therapeutic concentrations. This is why clinical cure rates for topical treatments are consistently low in published literature, often below 20%.

Why topicals fail and light succeeds
Nail Bed (fungal colonisation) Fungal Zone Nail Plate (keratin barrier) Topical BLOCKED 470nm Light
Topical treatments can't pass through the keratin barrier. 470nm blue light penetrates the nail plate to reach the fungal cells underneath.
Dual wavelength approach

Two wavelengths. Two mechanisms. One device.

CleraVita uses two specific wavelengths, chosen based on published phototherapy research. Each serves a different function in the recovery process.

470nm
Blue light
Blue light in the 405 to 470nm range has been shown in laboratory and clinical studies to inhibit the growth of dermatophytes, the family of fungi responsible for the majority of nail infections. The mechanism involves disruption of fungal cell processes through photodynamic action, damaging fungal cell structures without affecting surrounding human tissue at therapeutic doses.
910nm
Near-infrared
Near-infrared light at 910nm penetrates deeper into tissue, reaching the nail bed and surrounding vasculature. Published research on photobiomodulation shows that near-infrared wavelengths increase local microcirculation and support cellular repair processes. In the context of nail recovery, improved blood flow delivers more immune cells and nutrients to the treatment area.
Why 7 minutes?
Treatment duration is based on the energy density (fluence) needed to achieve a therapeutic effect at the nail surface. Our LED configuration delivers the studied dose in approximately 7 minutes per nail. Longer is not better. The auto shutoff ensures consistent dosing every session.
Research foundation

What the published research says.

CleraVita's approach is grounded in peer-reviewed studies on phototherapy for onychomycosis and photobiomodulation. We didn't invent the science. We engineered a device that applies it correctly at home.

Blue light phototherapy for superficial fungal infections
Multiple in vitro and clinical studies have demonstrated that blue light in the 405 to 470nm range exhibits antifungal properties against Trichophyton rubrum and Trichophyton mentagrophytes, the most common causes of onychomycosis.
Photobiomodulation and tissue repair
Near-infrared photobiomodulation has been extensively studied for wound healing, inflammation reduction, and increased microcirculation. Published meta-analyses support its role in accelerating cellular repair processes in skin and nail tissue.
Nail plate light transmission
Studies measuring optical properties of human nail plate confirm that visible light, particularly in the blue spectrum, transmits through the keratin structure at levels sufficient to reach the nail bed. This is the fundamental advantage over topical delivery.
Topical antifungal penetration limitations
Clinical literature consistently reports low cure rates for topical onychomycosis treatments, attributed to poor nail plate penetration. Even with nail lacquer formulations designed for extended contact, drug concentrations in the nail bed remain below therapeutic thresholds in most cases.
Safety profile

No pills. No chemicals. No side effects.

One of the primary reasons people choose light therapy over oral antifungals is the safety profile. Oral medications like terbinafine require liver function monitoring through blood tests. Light therapy is non-invasive and non-systemic. Nothing enters your body.

Non-invasive
Light is applied to the surface of the nail. No needles, no incisions, no contact with open tissue.
Non-systemic
Nothing enters your bloodstream. No liver monitoring required. No drug interactions.
Painless
Most users feel nothing. Some report a mild warmth during treatment, which is normal and expected.
Not UV light
CleraVita uses visible blue light (470nm) and near-infrared (910nm). These are not ultraviolet wavelengths. No UV exposure risk.
A note on expectations

What this can and can't do.

CleraVita is a light therapy device designed to support nail recovery from fungal infection. It is not a prescription medical device and it does not claim to cure onychomycosis. Results vary by individual, severity of infection, and consistency of use.

Most of our customers begin to see clearer nail growing in at the base within 4 to 8 weeks of daily use. Complete visible nail replacement takes longer because nails grow slowly, roughly 1 to 2mm per month for toenails. Severe or long-standing infections may take 3 to 6 months of consistent daily use.

If you have diabetes, peripheral neuropathy, or a compromised immune system, we recommend consulting your doctor before beginning any at-home nail treatment.

We offer a 90 day money back guarantee because we know that real results take time and we stand behind this product. If you're not seeing improvement after 90 days of consistent use, contact us for a full refund.
